Cleveland Cobalt Jobber Drill Bit
The Cleveland Cobalt Jobber Drill Bit is a 15/64 inch fractional drill bit built from cobalt steel with a TiAlN coating. It features a 135 degree notch point and parabolic flutes for efficient chip evacuation. Right hand cutting direction suits standard drilling operations. List number 2075TA identifies this high performance tool.
Suited for precise metal drilling
Machinists and fabricators drilling hard metals such as stainless steel or titanium will benefit from the cobalt substrate and heat resistant coating. The parabolic flute design supports deeper holes up to 2-5/8 inch flute length. Users needing coolant through capability or left hand cutting should look at alternative tooling.
135 degree notch point geometry
The 135 degree notch point reduces walking and lowers thrust required at drill entry. This point angle is the primary factor determining suitability for tough alloys versus softer materials. Verify the 0.2344 decimal equivalent matches your hole size requirement before purchase.

Questions about this item
Does the 135-degree notch point on the 15/64 cobalt drill bit run cooler during extended drilling?
The 135-degree notch point reduces thrust and heat buildup, while the parabolic flutes clear chips efficiently so the bit stays cooler during long drilling sessions.
Will the 15/64 shank fit my standard drill chuck without an adapter?
Yes, the shank diameter is 15/64 inch, matching the drill bit size, so it fits directly into any chuck that accepts that diameter.
Can the TiAlN-coated 15/64 cobalt bit be used in older drill presses with lower RPM ranges?
The 135-degree point and TiAlN coating perform well at moderate speeds; reduce feed pressure on older machines to avoid excessive wear.
