13/64 Cobalt Jobber Drill Bit
The Cleveland Golf 13/64 Parabolic TiAlN drill bit is built from cobalt steel for high-performance drilling. Its 135-degree notch point and parabolic flute design improve chip evacuation in deep holes. The TiAlN coating adds wear resistance for longer tool life. Right-hand cutting suits standard drill motors and drill presses.
Parabolic flute limits chip removal depth
Parabolic flutes excel at moving chips out of holes deeper than three diameters but can clog if feed rates are too low. The 135-degree point reduces thrust but requires rigid setups to prevent walking. TiAlN coating handles heat well yet offers less lubricity than uncoated tools in soft aluminium. Non-coolant-through design restricts internal cooling for very deep cuts.
Straightforward install with common mistakes
The 13/64-inch shank fits standard three-jaw chucks and collets without adapters. Ensure the chuck grips the shank past the flute start to avoid runout. Common errors include running too slow, which work-hardens the workpiece, and skipping peck cycles in holes over two inches deep. Dull bits often signal excessive speed or insufficient feed.

Questions about this item
Which 13/64 inch drill bit version should I choose from the list?
The supplier lists a single 13/64 inch Jobber drill with TiAlN coating, parabolic flutes, 135° point and notch point geometry under list number 2075TA; there are no alternative versions or capacities shown.
What does the 135 degree point angle mean once the bit is in a machine?
A 135° point reduces thrust and improves self-centring on hard materials, so the cobalt steel bit starts cleanly and tracks straight in a drill press or hand drill.
What shank standard does the 13/64 inch shank follow and what does it cap in practice?
The straight 13/64 inch shank fits standard three-jaw chucks and collets that accept fractional-inch jobber drills, limiting use to holders sized for that diameter.
