10.20 mm Cobalt Jobber Drill Bit
This Chicago-Latrobe jobber drill bit measures 10.20 mm in diameter and is manufactured from cobalt steel for extended wear resistance. It suits machinists and maintenance technicians drilling into tough alloys or stainless steel. The split-point geometry reduces walking at the start of the cut.
135-degree split point with .4016 decimal equivalent
The 135-degree split point centres quickly without a centre punch and the .4016 decimal equivalent simplifies imperial-tool selection. It is not designed for coolant-through applications or for materials requiring specialised coating technologies. Buyers needing internal coolant feed or alternative substrate grades should consider other options.
