Chicago-Latrobe 54111 Cobalt Drill Bit

This Chicago-Latrobe 54111 cobalt jobber drill bit is built for drilling metal with a 135 degree split point. The TiN coating reduces friction and extends cutting life. It suits trade and workshop users who need reliable hole-making in steel and alloys.

For machinists and maintenance teams

It suits machinists and maintenance teams drilling precise holes in ferrous materials. It is not for buyers who need coolant-through capability or larger diameters. Woodworkers and plastics fabricators should choose a different geometry.

135 degree split point with TiN coating

The 135 degree split point centres quickly and reduces walk on hard surfaces. The TiN coating adds wear resistance for longer production runs. Verify the .2900 decimal size matches your drawing before ordering.

Questions about this item

Will the 135° split point on this cobalt bit start cleanly in the existing holes I drill with standard HSS bits?

The 135° split point is self-centring and reduces walking, so it engages existing holes cleanly without a centre punch.

How can I confirm the 54111 bit is cutting correctly after chucking it in my drill press?

It should produce short, curled chips and a smooth hole wall at .2900 diameter with minimal pressure.

Does the 54111 come with a protective case or just the bare bit?

The bit has a TiN coating for wear resistance and a jobber-length flute for standard drilling depth.
