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.

Questions about this item
What does the 135-degree point angle mean for drilling performance?
The 135-degree notch point reduces walking and starts holes cleanly in hard materials without a centre punch.
Will the 9/32-inch shank fit a standard 3/8-inch drill chuck?
Yes, the 9/32-inch shank is smaller than a 3/8-inch chuck capacity and will clamp securely.
How do I use the parabolic flute design when drilling deep holes?
The parabolic flutes pull chips upward efficiently; withdraw the bit periodically to clear chips and prevent binding.
