Chicago-Latrobe 46496 Cobalt Jobber Drill Bit
The Chicago-Latrobe 46496 is a 12 mm cobalt jobber drill bit with a 135 degree split point. It is designed for drilling tough materials such as stainless steel and high-strength alloys. The straw bronze finish identifies the cobalt construction. This bit suits professional and industrial metalworking tasks.
Ideal for Hard Metals Not for Soft Materials
Machinists and maintenance technicians who drill stainless steel, titanium or hardened steel will benefit from the cobalt heat resistance and split-point accuracy. The 135 degree angle reduces walking on hard surfaces. Buyers who mainly drill wood, plastic or soft aluminium do not need this level of hardness and should choose a general-purpose bit instead.
12 mm Diameter Decides Fit
The 12 mm diameter, equivalent to .4724 inch, is the critical specification for matching the required hole size. The 151.00 mm overall length defines the reach available for the job. The bit has zero coolant holes and a non-coolant-through design. Verify the drill chuck capacity and workpiece thickness against these dimensions before purchase.

Questions about this item
How does the 135-degree split point behave once the bit is chucked in a drill?
The 135-degree split point centres itself on contact, reducing wander and the force needed to start a hole in metal.
What does the jobber-length shank imply for chuck compatibility?
The straight 12 mm shank fits any standard three-jaw chuck that accepts 12 mm or 1/2-inch capacity.
What physical clearance does the 151.00 mm overall length require?
The bit needs at least 151 mm of spindle-to-workpiece clearance plus room for the chuck body.
