Cleveland Golf Jobber Drill 5/16 TiAlN 135 Deg Parabolic

Cleveland Golf Jobber Drill 5/16

This Cleveland Golf jobber drill bit is a high-performance cutting tool made from cobalt steel with a TiAlN finish. It features a 135-degree notch point and parabolic flute design for efficient chip evacuation. The fractional size is 5/16 inch with a decimal equivalent of .3125. List number 2075TA identifies this specific model.

Suited for right-hand cutting in metal

This drill suits machinists and maintenance technicians who need a durable bit for general-purpose drilling in ferrous materials. The cobalt construction and TiAlN coating resist heat and wear during repetitive use. Buyers who require coolant-through capability or a different shank diameter should look at other tooling options.

Standard jobber shank fits common chucks

Installation is straightforward: secure the 5/16 inch shank in a matching drill chuck or collet. The right-hand cutting direction matches conventional drill presses and hand drills. The most common issue is premature wear if the workpiece material exceeds the bit's hardness range or if cutting speeds are incorrect.
