Chicago-Latrobe #50 Cobalt Jobber Drill

This new Chicago-Latrobe drill bit is a #50 wire-gauge jobber length tool made from cobalt steel. It is built for precise drilling in hard metals such as stainless steel and high-strength alloys where standard high-speed steel wears quickly.

Suited for hard-metal drilling; not for large holes

Machinists and maintenance technicians who need a 0.0700 inch split-point bit for accurate starting in tough materials will find this drill suitable. It is not intended for buyers who require larger diameters, coolant-fed operation, or high-volume production tooling.

135 degree split point for self-centering

The 135 degree split-point geometry allows the bit to center itself without a centre punch, reducing walk on hard surfaces. This single specification determines whether the drill matches the application.
