Cleveland Golf 2075TA 1/4 in Cobalt Parabolic Drill Bit 135° TiAlN

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.
