Product Description

Product Description

 

Drill bits of the "twist" variety are generally thought of as being general purpose in nature, due to their ability to bore holes in a wide variety of materials. Bits of this configuration typically feature 118-degree tips and are constructed of HSS (High-Speed Steel).

Though twist drill bits can be used on a variety of materials, they are seldom the most efficient bit for use in any specific application.

 

Concrete bits are designed to penetrate through concrete, brick, and block. Bits of this type feature a blunt Tungsten Carbide tip, which is brazed or welded in place.
Masonry drill bits are typically used in conjunction with a hammer drill, and penetrate by use of crushing power, rather than cutting.

 

A drill bit is the cutting tool that makes holes in metal. It forces bits of metal out the back and creates a hole to be able to use.Drill bits are available in both high-speed steel (HSS) and cobalt, which is the best for metal-based on how hard it is. HSS covered bits can be applied with metals that range from mild to stainless steel, while cobalt drill bits should only be used for harder materials like alloy steels or titanium.

A drill bit is a rotary cutting tool that makes holes. The point of the bit contacts the material you're drilling into, while the shank - the back end - is clamped in place by the jaws of a drill chuck.
Drill bits are primarily used for creating circular holes in materials from drywall and wood to metal and masonry. They might create a hole for an anchor or fastener, or a passage to feed wiring. Bits are sold individually and in multi-sized sets, commonly called drill indexes.
