Cobalt Parabolic Drill Bit
This Cleveland Golf jobber drill bit is a high-performance cutting tool made from cobalt steel with a TiAlN coating. It features a 135-degree notch point and a parabolic flute design optimised for deep-hole drilling. The fractional 1/4-inch shank and flute dimensions suit standard tool holders.
Suited for tough alloys and deep holes
Machinists drilling chilled cast iron, high-strength alloy steels, stainless steels, or tool steels will benefit from the parabolic flute geometry and wear-resistant coating. The non-coolant-through design limits use in applications requiring through-spindle coolant delivery or where internal cooling channels are mandatory for chip evacuation.
Fits standard 1/4-inch tooling setups
The right-hand cutting direction and 1/4-inch shank diameter allow direct fitment into common drill chucks and collets without adapters. The parabolic flute profile frees up chip clearance in deeper holes compared to standard twist drills, reducing the need for frequent pecking cycles during operation.

Questions about this item
What chuck size does the 1/4 in shank on this 2075TA bit require?
The bit has a 1/4 in shank diameter, so it fits any drill chuck that accepts 1/4 in straight shanks.
Will the 135° notch point on this cobalt bit start cleanly in stainless steel without a centre punch?
Yes, the 135° notch point is designed for self-centring in tough alloys such as stainless steel, reducing the need for a centre punch.
How can I confirm the TiAlN coating is intact after the first few holes?
Inspect the cutting edges; the gold-coloured TiAlN layer should show no silver cobalt steel exposed at the corners or along the flutes.
