Chicago-Latrobe 44950 Jobber Drill Bit

This Chicago-Latrobe 44950 jobber drill bit is a heavy-duty cutting tool made from cobalt material with a TiAlN coating. It features a 135 degree split point designed for self-centering and reduced walking. The bit is sized to letter F with a decimal equivalent of .2570 and has no coolant holes.

For metalworkers needing a durable letter F bit

Machinists and fabricators drilling hard metals such as stainless steel or high-temperature alloys will benefit from the cobalt construction and coated finish. The split point geometry helps start holes accurately without a centre punch. Builders requiring coolant-through capability or a different letter size should look at alternative tooling.

135 degree split point for self-centering starts

The 135 degree split point angle is the critical specification determining how the bit engages the workpiece. This geometry reduces thrust and prevents the bit from wandering on hard surfaces, making it suitable for portable or machine drilling where precise hole location is required.

Questions about this item

How much heat does the 135-degree cobalt bit generate during continuous drilling?

The 135-degree split point design reduces thrust and friction, lowering heat buildup when drilling steel and tough alloys with the cobalt construction.

What chuck size is needed to hold the 0.2570-inch shank on this jobber bit?

A standard 3/8-inch or larger drill chuck accommodates the 0.2570-inch diameter shank on this F-size jobber length bit.

Will this cobalt bit work effectively in an older corded drill with lower RPM?

Yes, the heavy-duty cobalt material and 135-degree split point perform well at lower speeds typical of older corded drills when cutting hard metals.
