Jobber Drill for Alloy and Stainless Steel

This Cleveland Golf jobber drill handles alloy, carbon, stainless and tool steel with a 15/32 inch cobalt steel body. The 135 degree split point reduces walking and starts holes cleanly in hard metals. Heavy duty grade construction supports production and maintenance drilling tasks.

Straight Shank Fits Standard Chucks Directly

The 15/32 inch shank diameter matches the flute size so the bit seats securely in any three jaw chuck without a reduced shank adapter. Right hand spiral flutes evacuate chips efficiently when the feed rate matches the 4xD depth to diameter ratio. Black oxide finish resists galling and extends edge life in abrasive alloys.

Cobalt Holds Hardness During Extended Drilling

Cobalt steel retains cutting hardness at the temperatures reached in sustained drilling cycles where high speed steel would soften. The split point geometry maintains centering through deep holes up to the 4xD limit without wandering. Black oxide surface treatment reduces friction and heat buildup during long production runs.

Questions about this item

How do I verify the drill bit is cutting correctly after setup?

A properly sharpened 135-degree split point should start on contact without walking and produce short, curled chips in alloy, carbon, stainless or tool steel.

What comes in the package and what must I supply?

The box contains the single 15/32-inch cobalt jobber drill with black-oxide finish; you provide the drill motor, work-holding and cutting fluid if desired.

Which version should I choose for a 4×D hole in stainless steel?

Select the 15/32-inch cobalt drill (List 3780) — its heavy-duty grade, 135-degree split point and black-oxide coating are rated for alloy, carbon, stainless and tool steel at a 4×D depth-to-diameter ratio.
