Cleveland Golf 5/32 Jobber Drill Parabolic TiAlN 135 Deg

5/32 Inch Cobalt Drill Bit

The Cleveland Golf jobber drill bit is a fractional inch cutting tool sized at 5/32 inch with a decimal equivalent of .1562. It is built from cobalt steel with a TiAlN coating for high-performance drilling. The 135 degree notch point and parabolic flute design aid chip evacuation in deep holes. This right-hand cutting bit suits maintenance and production environments.

Upgrade From Standard High-Speed Steel Bits

The TiAlN coating and cobalt substrate extend tool life when drilling chilled cast iron, high-strength alloy steel, stainless steel and tool steels. The parabolic flute geometry improves chip removal compared to conventional flute designs, reducing the risk of clogging in deeper cuts. The 135 degree point angle lowers thrust requirements for harder materials. The jump is worth it when standard bits wear quickly or fail to evacuate chips in these specific alloys.

Check Material Compatibility And Machine Setup

Verify the workpiece material matches the listed alloys: chilled cast iron, high speed steel, high-strength alloy steel, stainless steel and tool steels. Ensure the machine spindle runs right-hand rotation and can accommodate a 3-1/8 inch overall length with a 2 inch flute length. Confirm the shank diameter matches the chuck or collet capacity. Coolant-through capability is not required for this non-coolant-through design.
