Chicago-Latrobe 44922 Cobalt Drill Bit
This Chicago-Latrobe 44922 jobber-length drill bit measures 11/32 inch with a decimal equivalent of .3438. It is manufactured from cobalt high-speed steel and features a 135-degree split point for self-centering. A TiAlN coating increases surface hardness and wear resistance. The bit is designed for non-coolant-through applications.
Machinists drilling hard metals
The cobalt construction and 135-degree split point suit machinists drilling stainless steel, titanium and other tough alloys where standard high-speed steel wears quickly. The TiAlN coating extends tool life in high-temperature cutting. Buyers who need coolant-through capability or a different diameter should look at other tooling.
11/32 inch diameter with 135-degree split point
The 11/32 inch diameter determines the hole size this bit produces. The 135-degree split point geometry reduces walking and lowers thrust requirements compared to conventional points. Verify that your chuck capacity and workpiece material match these specifications before purchase.

Questions about this item
What does the 135 degree split point do when the bit is in the chuck?
The 135 degree split point reduces walking and starts the hole faster on hard materials without a centre punch.
How does the TiAlN coating on this cobalt bit affect drilling speed and heat?
The TiAlN coating increases surface hardness and heat resistance, allowing higher cutting speeds and longer life in steel and stainless steel.
What chuck capacity is needed for the 11/32 inch shank on this jobber bit?
A chuck that opens to at least 11/32 inch (0.3438 in) is required to hold the straight shank securely.
