Jobber Length Drill Bit 1/2 inch
This Cle-Line C23153 is a jobber length drill bit made from high speed steel with a black oxide finish. It features a 135-degree split point designed for self-centering and reduced thrust. The bit is intended for general-purpose drilling in metal, wood, and plastic.
Suited for 135-degree split point applications
This drill bit suits users who need a 135-degree split point for harder materials and improved accuracy without a centre punch. Buyers who require a coolant-through design for deep hole drilling or a different point geometry for specialised materials should look elsewhere.
135-degree split point geometry
The 135-degree split point is the key specification that determines suitability for harder materials and self-centering starts. This angle reduces walking and lowers the force required compared to standard points. Verify that your application calls for this specific point angle before purchase.

Questions about this item
Which diameter should I select for a 1/2 inch hole?
The decimal equivalent is 0.5000 inch, matching a 1/2 inch fractional size for standard jobber length drilling.
What does the 135 degree point angle do in steel?
The 135 degree split point centres the bit quickly and reduces walking on hard materials such as high speed steel workpieces.
How does the straight shank fit my drill chuck?
The jobber length bit uses a plain straight shank that clamps in any standard three jaw chuck up to 1/2 inch capacity.
