Cle-Line C22757 118° Jobber Drill Bit 1/2 in HSS Black Oxide

Cle-Line C22757 Jobber Drill Bit

This Cle-Line C22757 is a general-purpose jobber length drill bit made from high speed steel with a black oxide finish. It features a 118 degree conventional point angle and a 1/2 inch fractional size with a decimal equivalent of .5000. The bit is designed for non-coolant through applications and has zero coolant holes. It suits professionals and DIY users needing a reliable standard drill bit.

Suits standard drilling tasks in metal and wood

This bit suits users drilling common materials where a conventional 118 degree point performs well. It is not for buyers who need coolant-through capability for deep hole drilling or high-volume production. It also does not suit applications requiring specialised point geometries such as split points or parabolic flutes for improved chip evacuation. Users needing coated or carbide tooling should look elsewhere.

Simple chuck installation with standard shank

Installation requires securing the straight shank into a compatible drill chuck or collet. Ensure the chuck is tightened evenly to prevent runout during operation. What usually goes wrong is insufficient clamping force leading to slippage or using the bit on unsuitable materials causing premature wear. Always apply appropriate cutting fluid for the workpiece material to extend tool life.
