Do you know how to use a drill properly? Not everyone knows how to use a drill. Only a few is familiar with a drill and knows how to use them. Some stereotype and interchange hand drills to be the power drills that they are using nowadays. Well, there is a difference.
A drill is one type of tool that is used to create holes and drives screws in different materials like metal and wood. For the drill to be completely functional, drill bits are attached to it. Drill bits vary with the type of material it will be used for like drill bits for metals. These convert and amplify the circular motion of the drill chuck. With fast-paced technology, hand drills were already replaced by power drills. Nonetheless, many woodworkers still uses the basic hand drills since it is very portable and there is no limit to where holes can be made in materials.
When using a drill, make sure that it is held vertically. Turn the handles in a clockwise manner. If you turn it on a counterclockwise direction, it will be impossible to drill even small holes. One more thing, so as not to damage the work bench by the bit, put a scrap material (preferable wood) underneath the material to be drilled. Wear goggles if you feel necessary.
With improper use, drills may be damaged. This actually requires little maintenance. Just don’t use the wrong bits or adding excessive pressure on the drill. Place a drop of light oil on the crank pinions and chuck gears to use it in the best shape ever. This also prevents rust formation.
How To Use A Drill
Remember, that safety is a must no matter how basic the tool used. To start operating the drill, loosen first the chuck. Then insert the drill bit of choice, for example metal bits. The chuck should be tightened. There is a special tool to firmly tighten the chuck. Properly place the bit on the desired location and angle where you want the hole to be. The next step is to rotate the cranking handle in order to set these in motion. Holes can now be created by the drill. Applying excessive pressure may break or bend the bits. For a quality output, don’t drill fast. Always take your time. With these instructions, you now know how to use a drill.
Tie back long hair and secure any loose clothing or jewelries
Drill bits that are bent, dull or damaged must not be used
When inserting bits, make sure that they will not cover the fluted portion of the bit
If you are drilling metals, use a clamp to prevent the metal from spinning.
Use gloves when handling metals.
Be aware on where you place your fingers. You might drill a hole on it.
Start drilling when the drill is in contact with the work piece
For stalled power drills, never turn the drill on or off in an attempt to start the stalled drill because this will damage the drill.
Once done, clean up the work area and return drilling tool in proper places.
Basic things are the foundation of complex once. It will always be an added knowledge to know how to use a drill. Know more about it and explore further. You just don’t know one safety benefit this can provide you.
Nowadays, fixing things like putting up shelves and electrical boxes can be done by oneself. Hence, drilling tools are always present at homes. The drilling tools are specific to particular materials. Drill bits for metals are attached to a drill to create holes only for metal surfaces or materials. The same goes for wood drill bits or glass drill bits. Know more about these types of drilling tools and you might just improve the precision and outcome of your work.
A drill is used for drilling holes in a variety of materials or binding different kinds of materials. It is fitted with a cutting tool, usually a drill bit or a driving tool, using a driver bit. This is one of the types of drilling tools that are commonly used in construction, metal and woodworking. For those who wanted to save money, the hand drill can be used for do-it-yourself projects. There are certain types that are used in the medical field too. Drills may be powered manually or by compressed air (pneumatic drill), by electricity (electric drill) or by combustion engine (drilling augers).
This type of drilling tool is powered manually. Here are few examples:
The pistol-grip drill is the most commonly used tool today and already has several subtypes. There are subtypes that are used by plumbers and electricians.
A hammer drill uses a percussive action hence; it is suitable to be used on hard materials like bricks, concrete, stone (masonry) and rocks. This is typically used for installing shelves in concrete or electrical boxes.
These types are usually applied in boring holes or installing lead anchors in concrete like for benches or handrails. One distinguishing feature of this drill is that it can be used as drill only or hammer only.
The cordless drill uses rechargeable batteries. So make sure that you have an extra pack of batteries for continuous work!
These drilling tools are either mounted on stand or bolted on the floor and can work their way on steels. They are mostly used for woodworks but can also be used for honing, polishing and sanding.
Drill bits are tools that are attached to a drill. They make cylindrical holes and they come in standard sizes.
Universal bits can be used in most materials like wood, metal and plastic. Examples are as follows:
This section provides examples of drill bits for metals This type of drill bit is used for drilling holes on metal surfaces or materials. Examples are:
The wood drill bit enhances your wood working output. These types include:
Wood spade bits
Lip and spur bits
Spade bits – used for rough wood boring
Forstner bits – bore precise, flat-bottomed wood holes
Center bits – very compatible with drilling wood with a hand brace
Auger bits – effective for chip removal
Diamond core bits
This drill bit has a diamond embedded in its metal segments that are attached to the cutting edge. It can drill holes in glasses or on printed circuit boards (PCBs).
Masonry bits are attached to a hammer drill. These are used on rocks, stones, bricks and concrete.
Glass bits on the other hand have a carbide point that are spade-shaped and generates high temperature. The disadvantage of these drill bits are their short life cycle.
Holes in printed circuit boards (PCBs) are created by this type. These PCBs are mostly made of abrasive fiberglass making it unusable for steel bits.
There’s a wide array of appropriate manufacture for your drilling tools. Some may speak falsely on the quality of what they can offer. For convenience, here are the lists of the top brands of drills and drill bits. They are DeWalt, Craftsman, Hitachi, Makita, Bosch and Black and Decker. Now who have never heard of these brands? I bet you have one in your home right now.
For drill bits, Komet, Mikron, Seco, Alfra had made their names and has proven their worth and the quality of drill bits they produce.
Choosing The Right Type Of Drilling Tools
Always remember this golden rule when it comes to drilling tools: Make sure that you chose the right types of drilling tools for the right job. If you are a do-it-yourself person, you can buy an electric drill since it is easy to use and versatile.
Depending on your preference, you can either get an electric drill (corded) or go for a rechargeable drill (cordless). If you choose a rechargeable drill, make sure to ask for the price of rechargeable batteries before buying. They are costly at times. Rechargeable batteries have a limited life span so make sure you have spare battery packs ready. Since drill’s power is measured in Amperes, make sure to check how much ampere your drills have. The higher the Ampere, the more power your drill produces!
For all the drilling tools and supplies that you need, make sure that you know their respective uses and the amount of power they produce. Do not sacrifice the quality and capacity of your drilling tools. It pays to spend significant amount of money on an investment that would last several years than to waste money on low quality products that requires replacements every two to three months.
A glass drill bit just like any other drilling bit is used for cutting purposes. However, the glass drill bit is used primarily in the cutting of glass. The bits are fitted into a drill which rotates at a very high speed resulting in the smooth boring of cylindrical holes of varying sizes in glass. The terms drill bit and drill usually cause confusion as they are sometimes used to describe both the cutter which is the drill bit and the holder of the cutter which is the drill.
The glass drill bit is used together with the electric powered drill to drill holes through glass and other glasslike materials such as tiles and ceramics. A glass cutting drill bit usually has its tip coated with pieces of industrial diamond which help in the drilling process. The diamond pieces rub their way through the glass in an action that can only be described as similar to that of sandpaper. This minimizes the risk of breakages and cracks. The finesse of the rubbing action of a diamond drill bit for glass depends on its texture which might range from very fine to rough. This ensures that the diamond coating found in different glass drill bits matches to their intended task.
Difference Between A Glass Cutting Drill Bit And Other Drilling Bits
Metal and wood drill bits usually have their design based on the ever popular traditional twist architecture. The resulting flutes in metal and wood drill bits are used to bore into the material as well as in guiding waste material out of the hole. The diamond drill bit for glass on the other hand is straight, smooth—devoid of the flutes common in metal and wood drill bits and has a texture that can be aptly categorized as rough. When glass is being drilled, the ensuing waste material is a fine dust which does not need to be removed like is the case with wooden and metal shavings.
It is possible to sharpen drill bits for metal and wood once their cutting edges start being blunt. However, a glass drill bit is rendered useless once its diamond coating wears off. The longevity of the glass drill bit depends on several factors.
Factors Affecting Longevity Of Glass Drill Bit
The diamond coating of the drill bit for glass can last for years or it can last only for the duration it takes to drill a single hole. The drill should be continuously monitored so as to avoid sudden breakages and cracking which might be dangerous.
The glass cutting drill bit should be used in a well lubricated environment for optimum results. Lubrication of a glass drill bit can easily be done using water which is directed over to the drilling point. However, utmost care should be observed especially when working with electric drills. Should the drill get in contact with water, serious harm to both the machine and operator may arise. The glass drill bit should always be used with moderate to light pressure and should ideally be left to drill the glass at its own natural speed.
Diamond drill bits are great and ideal for both large scale industrial applications and for home use. Diamond tipped drill bit are used while working on wood, metal or any other material. Diamond is one of the most-sought after constituent component in drills bit. This is due to its remarkable physical and molecular properties that place it as the hardest substance known to man. This hardness makes it invaluable when it comes to resisting wear and tear. This happens to be the most obvious concern when it comes to the maintenance of the drill bits when used repeatedly on various surfaces. Diamond tip drill bit solves this problem.
Materials Used In Making Diamond Drill Bits
It is widely held that the more a diamond drill bit costs the more resistant it ought to be. Judging from the sales figures collected from some of the leading hardware equipments retailers the twist drill with its deep, spiral grooves is by far the most popular tool sold. The twist drills are drill bits for metal that belongs to a larger group of tools referred to as High Speed Steel or simply abbreviated as HSS. They have remarkable abilities of being able to resist extreme temperatures and are generally more resistant to wear and tear as opposed to their predecessors; the high carbon steel.
So besides Diamonds, what other alloys are used in Diamond drill bits? This enhanced degree of resistance is attributed to fusing the bits with vanadium. Other alloys fused to make the diamond drill bit apt for all materials which include chromium, tungsten and molybdenum. For easy maintenance and cleaning, most of HSS are finished off with a coating of Titanium nitride which also serves to lengthen the life span of the tool. The material for the diamond drill bit influences the surface they will be able to function in. Apart from HSS other materials you will find in other tools are both high and low carbon steel and the cobalt steel alloys.
Other Factors To Consider When Buying A Diamond Drill Bit
- The shape of the drill bit also determines other factors like the type of hole it is going to drill. For instance the screwdriver with its hexagonal shaped head is ideal for boring small pilot holes before a larger tipped drill comes into action to make larger ones.
- The shape of the bits also plays a pivotal role in how your material will behave after making a hole. Some materials like glass or softwood have a tendency to crack and split if you make a whole with the wrong tool. This is where a diamond core drill bit becomes handy. It is specially designed for drilling thru super hard materials and at the same time creating slightly bigger holes.
Always be reminded that when working with various drills on varied materials to consult with professionals lest you risk spoiling both the materials and the tools as well. This is the only place you can learn the subtle differences between a masonry bit meant for working with stones, concrete and bricks from the costlier diamond drill bit which is utilized for drilling metals.
Drill bits for metal are the replaceable accessories or parts of mechanical drills. Just like knives, blades, and razors, the drill bits should always be sharp and pointed to fulfill its tasks of drilling holes or breaking through material surfaces. The use of drill is a known engineering or building necessity. They are needed in construction, home building or improvement, heavy industries, or even in simple crafts and projects. The good thing about mechanical drills of today is that the bits could already be replaced when the tips or points worn out or when a particular bit is required for a certain material or drilling requirement.
Types of Drill Bits for Metal
If you would try to consult an expert, you will eventually learn that there are hundreds of types, kinds, and styles of drill bits available on the market. They are generally distinguished according to their make, the type of holes they make, the materials they are intended for use, their point or sharpness, and few other determinants. Nonetheless, the following are the most common types or kinds of metal drill bits.
The High Speed Steel Bits. These bits are commonly termed as the HSS drill bits. They are the most common bits installed on mechanical drills for an all-purpose use. They bore on wood, plastic, and serve as good long drill bits for metal.
The Titanium and Cobalt HSS Bits. The Titanium and the Cobalt drill bits for metal are improved versions of the HSS drill bits. As their name suggests, these bits are plated with Titanium and Cobalt. Titanium nitrate according to experts extends the cutting or boring sharpness of the bits while the Cobalt coated ones are resistant to weathering intense temperature changes or pressures, abrasion, etc.
Multi-Purpose Bits. Another innovation with the HSS drill bits is the multi-purpose bits. These bits features a diamond ground tungsten tip that is ideal for use to almost all types of materials like wood, concrete, plastic, ceramic, and also serves as drill bits for metal.
Masonry bits. The masonry bits are used for boring holes in stone, brick, cement, or concrete.
Spear Point Bits. This kind of bit features a spear-like tip and is designed to cut through the fragile tiles and glass surfaces.
Reduces Shank HSS Bits. The reduced shanks are shorter bits but larger in diameter and are used to drill larger holes of up to 16 millimeters.
Rivet Bits. The rivet drill bits are used to create holes on metals, aluminum, and other materials where rivets are intended to be placed.
Spade bits. The tips of these bits are shaped like the common spade’s contour or appearance. These bits are also used for boring larger holes specifically for wood.
Step Drill bits. The step drill bits take the shape of a cone or staircase. They are primarily used for enlarging existing holes or perhaps, for light deburring.
As mentioned above, there are hundreds of kinds or types of drill bits for metal available that would still go next unto the above list. But the foregoing ones are among the most common and widely used.
Few Buying Tips for Metal Drill Bits
Determine the type of material or metal the drill bits are to be used. This would save time in making comparisons when shopping.
The size or diameter of the hole created is another important consideration. Your building or construction project certainly requires a specific size or diameter including the depth of the hole created.
For the best drill bits for metal, you should rather go for the cobalt or titanium plated ones for a longer lasting drilling performance.
Functions of Metal Drill Bits
With the numerous kinds and styles of drill bits for metal, they usually have the same functions or uses, mainly to drill or create a hole in almost all types of building and crafting materials like wood, metal, plastic, ceramic, glass, aluminum, etc. Among the secondary or accessory purpose is to create initial holes or fits for screws, nails, securing bars, rivets, and others.
