Cobalt Jobber Drill Bit Size C
This Chicago-Latrobe 54103 cobalt drill bit is built for professional metalworking where heat resistance and wear life matter. The split-point geometry reduces walking and starts holes cleanly in tough alloys. It suits machinists and maintenance crews who need reliable performance in stainless steel, titanium and other hard materials.
135-Degree Split Point for Hard Metals
The 135-degree split point is the specification that decides fit: it centres without a centre punch and cuts efficiently in high-tensile workpieces. Buyers drilling soft wood, plastics or thin sheet metal will not benefit from this geometry. The .2420 decimal equivalent matches letter size C for precise hole tolerances.

Questions about this item
How does the 135-degree split point affect drilling in metal?
The 135-degree split point centers itself without a pilot hole and reduces walking on hard materials such as stainless steel.
What does the .2420 decimal size mean for my drill chuck?
The .2420 inch diameter matches a standard letter-size C bit and fits any 1/4-inch or larger three-jaw chuck.
