Drill Bit Material Chart

Titanium coating makes these bits harder and last longer than the common hss bits.

Drill bit material chart. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill which powers them to cut through the workpiece typically by rotation. Drill bits are cutting tools used to remove material to create holes almost always of circular cross section. Bit for metal bits for metal cuts through steel are designed for heavy duty work and the most expensive of the drill bits.

Cobalt hsco is considered an upgrade from hss because it includes 5 8 cobalt blended into the base material. Style a charts provide decimal equivalents of fractions wire gauge drill sizes letter drill sizes and metric sizes. If you are having problems with excessive heat build up or dulling of hss tooling you can try this type if drill to solve the problem. Flatter points such as those with 135 degree angles are suited for drilling into harder material.

Style b charts provide a pipe tap drill chart as well as decimal equivalents of tap drill sizes fractions wire gauge drill sizes letter drill sizes and metric sizes. That is because the coating is a hard ceramic material. Bits with steeper points such as those with 118 degree angles are. Also known as a core drill bit the annular cutter is used to cut a hole in such a way that the core of the material is left intact and then to retrieve the core from the material.

For a typical drill bit the angle of the point helps determine what type of material the bit can drill. Titanium coated drill bits tin tian ticn more. This is a great option for drilling into harder steel as well as stainless steel grades.
