Chicago-Latrobe 54112 Cobalt Drill Bit
The Chicago-Latrobe 54112 is a jobber length drill bit manufactured from cobalt steel with a titanium nitride coating. It is designed for professional mechanics and metalworkers who require a durable cutting tool for drilling hard materials such as stainless steel and high-strength alloys. The split point geometry allows for accurate starting without a centre punch.
135 Degree Split Point Performance
The 135 degree split point reduces walking and lowers the thrust required to penetrate tough workpieces. Cobalt construction maintains hardness at elevated temperatures generated during sustained drilling operations. The TiN coating reduces friction and wear, extending the service life of the bit during repetitive production tasks.
M Size .2950 Decimal Equivalent
Verify that your drill chuck accommodates the straight shank of this jobber length bit. Confirm that the .2950 inch diameter matches the hole specification for your application, as this size corresponds to the letter M gauge. Ensure your workpiece material and machine rigidity are suitable for cobalt tooling without coolant through holes.

Questions about this item
Does the 135° split point on the 54112 cobalt bit run cooler during extended drilling?
The 135° split point reduces thrust and walking, which lowers friction and heat build-up during long drilling sessions.
What shank style does the 54112 bit need so it fits my drill?
The 54112 has a standard jobber-length round shank that fits any three-jaw chuck or collet sized for .2950 in.
Can the 54112 cobalt bit handle the mild steel and aluminium I already work with?
Cobalt construction with TiN coating gives the 54112 the hardness and wear resistance needed for mild steel, aluminium and similar materials.
