Sandvik Coromant - #54, 118° Point, Solid Carbide Micro Drill Bit

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.

Uncoated tools do not feature supportive treatments on the cutting edge. They are are used at reduced speeds in general applications on non-ferrous metals.

Spiral flute reamers are used in blind and through-hole operations. They are used to bridge interrupted cuts.

Slow spiral bits have wider flutes and used in heavier feeds. They are used on concrete and nonferrous materials including aluminum, brass, copper and cast iron.

Straight shanks are used for general purpose applications. The shank is smaller than the drill bit diameter. They are used with portable drills and drill presses on ferrous and non-ferrous materials.
