Cleveland Golf Jobber Drill 1/2 In Parabolic Cobalt
This Cleveland Golf jobber drill is a high-performance cutting tool built for professional metalworking tasks. It targets machinists and maintenance technicians who require reliable hole-making in tough alloys. The cobalt steel construction supports extended tool life under demanding conditions.
Upgrade from standard high-speed steel bits
The cobalt steel material and parabolic flute design replace conventional bits that wear quickly in hard materials. The jump is worth it when drilling stainless steel or high-tensile alloys where heat resistance and chip evacuation are critical for success. The 135 degree notch point reduces walking at the start of the cut.
Fits standard 1/2 inch chucks for right-hand cutting
The straight shank matches the 1/2 inch drill diameter for secure clamping in common drill presses and handheld units. Right-hand cutting direction suits standard machine operation. The parabolic flute geometry frees up chip removal in deep holes up to 4-1/2 inches without pecking cycles.

Questions about this item
Will a 1/2 inch shank fit my drill chuck?
The shank diameter is 1/2 in., so it requires a chuck that opens to at least that size.
How do I start the hole with the 135 degree notch point?
The 135-degree notch point is self-centering; apply steady pressure without a centre punch to avoid wandering.
When should I replace this cobalt parabolic drill bit?
Replace it when the cutting lips become rounded or the straw/bronze finish wears away, indicating lost hardness.
