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.titanium drill bits for metal

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.
