15-piece tin-coated jobber drill set

This 15-piece tin-coated jobber drill bit set from Drill America is built for machinists and maintenance technicians who regularly drill hard metals and work-hardened stainless steel. The titanium nitride surface treatment extends drill life and improves chip ejection during repetitive operations.

Jobber-length bits for standard chucks

The jobber-length design fits common drill chucks without special adapters, freeing the user from sourcing reduced-shank or stub-length alternatives. Tin coating lowers the horsepower needed at the spindle, so the set works on lighter bench-top presses as well as larger floor models.

Tin coating reduces wear and power draw

The titanium nitride layer cuts friction, which decreases horsepower requirements and helps maintain sharpness in abrasive alloys. A California Proposition 65 notice applies because the product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.
