Heavy-Duty Drill Bit for Precision Work
This Chicago-Latrobe jobber-length drill bit is built for demanding drilling tasks. Its high-speed steel construction with TiCN coating resists wear in tough materials. The 135-degree split point starts cleanly without walking. It suits machinists and maintenance technicians who need reliable performance.
Suited for Hard Materials and Accurate Starts
The split-point geometry and hard coating make this bit effective in stainless steel and other hard alloys. It is not designed for coolant-through applications because it has zero coolant holes. Buyers who require internal coolant delivery should look at a different drill design.
135-Degree Split Point Controls Accuracy
The 135-degree point angle combined with a split-point tip reduces thrust and prevents the bit from wandering on contact. This single feature determines whether the bit matches the precision requirements of the job.

Questions about this item
What does the 135-degree point angle do for drilling performance?
The 135-degree split point reduces walking and starts holes cleanly in harder materials without a centre punch.
How does the TiCN coating affect the bit's working life?
TiCN coating increases surface hardness and heat resistance so the bit stays sharp longer in steel and stainless steel.
What chuck size is needed to hold the .3680-inch shank?
A standard 3/8-inch or larger drill chuck will grip the .3680-inch diameter shank securely.
