Cobalt – Cobalt bits are a special formulation of high speed steel with cobalt added in to withstand very high drilling temperatures. Cobalt bits are specifically designed for drilling very hard, abrasive materials such as treated stainless steel, titanium and cast iron. Cobalt bits are not designed for general purpose use.  Vermont American cobalt drill bits feature the following: (1) grip tight shank for positive chuck hold, (2) cobalt withstands high drilling heat for longer bit life and includes thick web for increased durability and (3) 135 degree split point starts fast and reduces drill walking.  Click here to see available sizes.

Whether your late night is 8 PM, 11 PM or 3 in the morning, we've got you covered with your flame-grilled faves when you need them most.

118° Point – Designed primarily for drilling into wood or plastic. Center punch is required for drilling into metal, otherwise bit will “walk” or “skate”.

Titanium – High speed steel bits which have been coated with titanium nitride. This special coating gives the bits a very high surface hardness to help penetrate tough materials, makes the bits highly corrosion resistant and significantly reduces friction between bit and workpiece. Titanium coated bits last up to 6X longer than standard high speed steel bits.  Vermont American titanium drill bits feature the following:  (1) grip tight shank for positive chuck hold, (2) titanium coating hardens bit surface or improved durability in tough, repetitive applications and acts as lubricant, requiring less torque and less heat build-up for longer bit life, (3) speed helix augers dust away from tip more quickly, reducing heat for long life and (4) 135 degree split point starts fast and reduces drill walking.  Click here to see available sizes.

High Speed Steel (HSS) – Standard general purpose bits with a polished finish with silver appearance.  Click here to see available sizes.
