Suits Left Hand Helix Applications

Machinists needing a left hand helix for reverse rotation tasks will find this bit appropriate. The conventional point works in standard drilling operations without coolant through holes. Buyers requiring coolant fed drilling or coated bits for extended wear should look at other designs. The fractional inch sizing fits imperial tooling systems.

High Speed Steel Capacity

The high speed steel construction handles general purpose drilling in metal, wood and plastic. The 118 degree point provides reliable centering in softer materials. The bright finish offers no thermal barrier so heat builds faster in hard alloys or deep holes. The jobber length gives standard reach for typical workshop tasks.
