12 mm Cobalt Jobber Drill

The Chicago-Latrobe 48014 is a 12.00 mm jobber-length drill bit made from cobalt high-speed steel with a titanium nitride coating. Its 135-degree split point allows accurate starts on hard materials without a pilot hole. The metric sizing and decimal equivalent of .4724 match standard drill charts for precise work.

Suited for metalworkers and maintenance teams

This bit is built for drilling stainless steel, titanium and other tough alloys where cobalt hardness and heat resistance matter. Users who need coolant-through capability or a different point angle for specialised applications should look at other tooling options.

Questions about this item

What does the 135-degree split point do when the bit enters the workpiece?

The 135-degree split point centres the bit without a pilot hole and reduces walking on hard materials.

How does the straight shank limit use in different chucks?

The straight shank fits standard three-jaw chucks but cannot be used in SDS or hex quick-change systems.
