Cleveland Golf Jobber Drill 25/64

This cobalt steel jobber drill bit features a 135 degree split point and a black oxide finish. It measures 5-1/8 inches overall with a flute length of 1-7/8 inches. The heavy duty grade tool is designed for drilling alloy, carbon, stainless and tool steel. Its right hand cutting direction suits standard drilling operations.

The split point geometry reduces walking on tough alloys and stainless steels. Cobalt construction resists heat during extended cuts in tool steel. Builders needing coolant-through capability or left hand cutting should look elsewhere. The fractional 25/64 inch shank fits matching collets or chucks only.

The split point starts on contact without a centre punch in most materials. Black oxide finish helps retain lubricant during deep hole drilling. Overheating cobalt shortens edge life if feed and speed are not matched to the workpiece. Ensure the shank seats fully to prevent runout at the 135 degree point.

Questions about this item

What drill chuck size do I need to hold the 25/64 inch shank?

Use a chuck that opens to at least 25/64 inch (0.3906 in.) to grip the shank securely.

Can I run this cobalt bit in a standard portable drill motor?

Yes, the 135-degree split point and right-hand spiral flutes work in any standard drill with sufficient torque for heavy-duty steel.

How do I confirm the bit is cutting correctly after I start drilling?

Look for clean, continuous chips and a centred hole start; the split point should prevent walking on alloy, carbon, stainless or tool steel.
