Cleveland Cobalt Jobber Drill Bit 11/32
This 11/32 inch cobalt steel drill bit is built for heavy duty drilling in alloy, carbon, stainless and tool steel. The 135 degree split point design provides accurate self centering starts without a centre punch. Black oxide finish adds lubricity and corrosion resistance for longer tool life.
Suited for machinists drilling tough metals
The straight shank matches the drill diameter of 11/32 inch and fits standard three jaw chucks. It is not for use with coolant through systems or left hand rotation spindles. Buyers needing reduced shank diameters for smaller chucks or coolant fed drilling should look at other tooling.
135 degree split point angle
This single specification determines how the bit starts and cuts in hard materials. The aggressive point geometry centres itself instantly in stainless and tool steel where standard points would walk. If your application requires a different point angle for specific chip formation or hole finish, this bit will not meet that requirement.

Questions about this item
How does the 135-degree split point behave when the bit first contacts the workpiece?
The 135-degree split point centres itself on alloy, carbon, stainless or tool steel without a centre punch, reducing walk and cutting the chip immediately.
What does the straight 11/32-inch shank limit in a drill chuck?
The straight 11/32-inch shank fits only chucks that open to at least 11/32 inch; it cannot be used in smaller-capacity chucks or reduced-shank adapters.
Will the 4-3/4-inch overall length clear a 3-7/16-inch deep hole in one pass?
Yes — the 3-7/16-inch flute length matches the 4xD depth-to-diameter ratio, so the flutes evacuate chips from a full-depth hole without pecking.
