Cleveland Golf
Cleveland Golf Jobber Drill Parabolic #10 Cobalt 135°
Cobalt steel jobber drill with 135° parabolic flute and notched point for stainless and hardened alloys
- #10 wire size for precise 0.1935 in. holes
- 135° parabolic point cuts chilled cast iron and stainless
- Cobalt steel resists heat in high-strength alloys
- Parabolic flute design clears chips and improves coolant flow
- Notched point reduces work hardening and boosts stability
Cleveland Golf Jobber Drill #10
This Cleveland Golf jobber drill is a single high-performance cobalt steel cutting tool built for precision metalworking. Its parabolic flute design and 135-degree notched point target professionals drilling difficult alloys.
Suited for tough alloy and stainless jobs
Machinists working with chilled cast iron, high-strength alloy steel, stainless steel or tool steels gain closer tolerances and better chip control. Buyers needing multiple sizes or a full drill set should look elsewhere.
Parabolic flute manages heat in deep cuts
Wider flute spacing and TiAlN coating resist oxidation while improving coolant flow during sustained drilling. The modified notch point reduces work hardening so the bit stays stable through extended production runs.

Questions about this item
What chuck size do I need to hold the .1935 inch shank on this drill?
A standard three-jaw chuck that closes fully to .1935 inch will grip the shank securely; most 3/8 inch or 1/2 inch capacity drill chucks handle this size without an adapter.
Will the 135 degree notched point cut cleanly in the chilled cast iron and stainless steel I already machine?
Yes, the 135 degree parabolic flute and modified notch point are designed for chilled cast iron, high-speed steel, high-strength alloy steel, stainless steel and tool steels, reducing work hardening and improving chip flow in those materials.
How can I confirm the TiAlN coating is performing after I start drilling?
Look for consistent gold-coloured wear on the cutting edges, tight chip formation exiting the wider flutes, and hole diameters staying within tolerance without excessive heat discoloration on the workpiece.
