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.

Questions about this item
What size drill chuck do I need for the 1/2 inch shank on this bit?
A chuck that opens to at least 1/2 inch is required to hold the shank securely.
Will the 118 degree point angle cut effectively in the mild steel I usually drill?
Yes, the 118 degree conventional point is designed for general purpose drilling in materials like mild steel.
How can I confirm the bit is cutting correctly once I start drilling?
Steady, curled chips and a clean hole at the 0.5000 inch diameter show the bit is working as intended.
