Things To Consider When Buying Drill Bits

When it comes to buying drill bits, there are few important things you need to keep in mind. Here is a buyer’s guide to help you out.

Material type

The first important thing to consider is the type of material the drill bit is made of. Most of them are made of cobalt, carbide, or high-speed steel. The material of the drill bit can influence how effective it is at drilling. For instance, high-speed steel is suitable for drilling non-ferrous and ferrous metals. Carbide is best for drilling non-ferrous metals, while cobalt is good for ferrous metals.

Shank design

By shank, we mean the non-drilling part of the drill bit. It is the end that you plug into the drill. The size of the bit should match the chuck size of your drill. There are two types of shanks, one is a non-spin shank, which has a fluted shank. The second is a hex shank which looks similar to a screwdriver.

Coating

Even the coating of the drill bit is an important factor. Most metal drill bits are coated with black oxide or titanium. This helps reduce friction which ultimately prevents the bit from heating up and breaking. Not just that, but it also increases the speed.
