Chicago-Latrobe 44962 Cobalt Jobber Drill Bit

This Chicago-Latrobe 44962 is a heavy-duty jobber length drill bit made from cobalt with a TiAlN coating. It features a 135 degree split point designed for self-centering and reduced thrust. The bit is built for drilling tough materials in professional and industrial settings.

Suited for metalworkers drilling hard alloys

The split point geometry and cobalt construction serve machinists and maintenance technicians who need accurate holes in stainless steel or high-tensile materials. Buyers who require coolant-through tooling for deep-hole drilling or high-volume production runs should look at alternative designs.

135 degree split point with TiAlN coating

The 135 degree split point allows the bit to start on contact without a centre punch, while the TiAlN coating increases surface hardness and heat resistance. Together they extend tool life and improve chip evacuation when drilling at the .3390 inch decimal equivalent size.

Questions about this item

How do I confirm the 135-degree split point is cutting correctly after I start drilling?

The split point should self-centre and produce short, curled chips in steel without wandering or excessive heat buildup.

What comes in the box and what must I supply separately?

The box contains the single cobalt jobber drill bit; a compatible drill chuck and cutting fluid are not included.

When should I choose the .3390-inch size over another letter size?

Select the .3390-inch letter-R bit when the hole diameter must match that exact decimal equivalent.
