7/64 Cobalt Jobber Bit
This 7/64 inch cobalt jobber drill bit is designed for drilling hard metals such as stainless steel and titanium alloys. The 135 degree split point reduces walking and starts holes accurately without a centre punch. It suits maintenance technicians and metal fabrication shops that need reliable performance in tough materials.
Split point eases installation
The split point geometry allows the bit to self-centre in a standard drill chuck, so no pilot hole or special holder is required. The main issue arises when the bit is run at excessive speed or without cutting fluid, which can overheat the cobalt substrate and dull the cutting edges prematurely.
Verify chuck capacity and material
Confirm that your drill chuck accepts a 7/64 inch shank and that the workpiece material matches the bit's intended range of hard steels and alloys. The bit is not coolant-through, so external lubrication must be supplied for deep holes. Check that the 135 degree point angle suits your hole quality requirements.
