Chicago-Latrobe 44945 Cobalt Drill Bit
The Chicago-Latrobe 44945 is a jobber-length drill bit made from cobalt alloy with a TiAlN coating for hardness and heat resistance. Its 135-degree split point reduces walking and starts holes cleanly in tough materials. Decimal size .2340 suits letter-gauge drilling tasks. It is built for machinists and maintenance crews who need repeatable accuracy in steel and alloys.
Thermals, Noise and Power Draw in Normal Use
The bit runs cooler than standard high-speed steel because the cobalt substrate and TiAlN coating dissipate cutting heat efficiently. No coolant-through design means external lubrication manages temperature during deep cuts. Power draw depends entirely on the drill motor and feed rate used by the operator. Operation is quiet apart from the host tool and material contact.

Questions about this item
How do I install the 135 degree split-point bit and what step do users often miss?
Clamp the bit in a drill chuck, centre the split point on the mark, and apply steady pressure; the step often missed is clearing chips frequently to prevent the cobalt flutes from binding.
What maintenance or replacement will the cobalt jobber bit need later?
Resharpen the 135 degree split point when it dulls, and replace the bit once the .2340 diameter wears undersize or the TiAlN coating is gone.
