Cleveland Golf Jobber Drill 9/32 Cobalt Parabolic 135° 2075

Cleveland Golf Jobber Drill 9/32

The Cleveland Golf Jobber Drill 9/32 Cobalt Parabolic 135° 2075 is a fractional-inch cutting tool built for precision metalworking. Its 9/32 inch diameter and .2812 decimal equivalent suit machinists and maintenance technicians who need accurate hole sizing in tough alloys. The 135-degree notch point reduces walking and lowers thrust requirements during operation.

Cobalt steel construction with parabolic flutes

Cobalt steel construction delivers high heat resistance and extended edge life when drilling stainless steel or high-strength materials. Parabolic flute geometry promotes efficient chip evacuation in deep-hole applications, reducing clogging and heat buildup. The straw-bronze finish adds surface lubricity while the straight shank fits standard 9/32 inch chucks and collets without adapters.

Upgrades standard high-speed steel bits

This drill replaces general-purpose high-speed steel bits where work-hardening materials cause rapid wear or breakage. The cobalt substrate and parabolic profile justify the step up for production runs or difficult alloys that demand consistent hole quality. Shops drilling shallow holes in mild steel or aluminium will not see a proportional benefit over conventional tooling.
