Cleveland Golf 23/64 Cobalt Jobber Drill

The Cleveland Golf 23/64 Cobalt Jobber Drill is a high-performance cutting tool designed for metalworking professionals and maintenance technicians. Its cobalt steel construction resists heat and wear during repetitive drilling tasks. The fractional-inch sizing suits imperial measurement workflows. This bit targets users who need durable performance in hard materials.

135-degree notch point with parabolic flutes

The 135-degree notch point reduces thrust pressure and prevents walking on hard surfaces. Parabolic flutes evacuate chips efficiently from deep holes without clogging. Cobalt steel maintains hardness at elevated temperatures generated during extended cuts. The straw bronze finish adds lubricity and corrosion resistance for longer service life.

Straight-shank design fits standard chucks

The 23/64 inch shank diameter matches the drill diameter for direct insertion into three-jaw chucks or collets. Right-hand cutting direction works with conventional drill motors and drill presses. Non-coolant-through design requires external flood or mist cooling in deep-hole applications. Users must verify machine rigidity to prevent deflection at this diameter.

Questions about this item

How does the 135-degree point angle behave when drilling into hard steel?

The 135-degree notch point reduces walking and requires less thrust, letting the cobalt steel bite into hard materials without a centre punch.

What does the parabolic flute design change about chip removal?

Parabolic flutes have a wider, smoother helix that pulls chips out of deep holes faster than standard flutes, reducing heat build-up in the 3-1/2 inch flute length.

Will the 23/64-inch shank fit a standard three-jaw drill chuck?

Yes, the shank diameter matches the 23/64-inch drill size, so it clamps directly in any chuck that accepts up to 3/8-inch capacity.
