Straight flute drills are used for drilling holes in hardened and high strength steels over 50 HRC. The straight flute allows for deep hole drilling.

Solid carbide provides better rigidity than High Speed Steel (HSS). It is extremely heat resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.

Aluminum titanium nitride (AlTiN) is one of the most abrasive resistant and hardest of the coatings. It is commonly used for machining aircraft and aerospace materials, nickel alloys, stainless steel, titanium, cast iron and carbon steel.
