Precision Twist Drill 010019 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 010019 is a high-speed steel (HSS) jobber-series drill bit built for cutting through hard surfaces under demanding conditions. With a 19/64-inch tip diameter and a 4-inch depth of cut, this bit is sized for a wide range of through-hole and deep-hole drilling tasks encountered in mechanical, HVAC, plumbing, and electrical trade work. The HSS construction resists heat buildup during high-feed drilling, maintaining cutting edge integrity longer than standard carbon-steel alternatives. Overall length is 4-3/8 inches. Sold as a single unit.

This jobber-length drill bit is suited for trade professionals working in sheet metal, structural steel, pipe flanges, electrical enclosures, and similar hard-surface applications. It fits standard 3/8-inch and 1/2-inch keyed or keyless drill chucks found on corded and cordless drill drivers and drill presses commonly used in residential and commercial mechanical installations.

Compatibility

Designed as an OEM-style replacement and standard jobber drill bit compatible with any 3/8-inch or 1/2-inch chuck drill driver or drill press accepting standard straight-shank HSS drill bits.

Installation Notes

A licensed or qualified tradesperson should select the correct cutting speed and feed rate for the material being drilled to avoid overheating and premature bit wear. Secure the workpiece firmly before drilling and use cutting fluid or coolant when drilling ferrous metals to extend bit life. Ensure the drill chuck is fully tightened and the bit is seated straight before beginning a cut. Follow applicable OSHA hand and power tool safety standards when operating rotating cutting equipment.
