Precision Twist Drill 010317 Hss Cobalt Jobber Drill 17/64 in

Product Description

The PRECISION TWIST DRILL 010317 is a heavy-duty HSS cobalt jobber drill designed for drilling into hard and abrasive materials. Built with a straight shank and conforming to Type J jobber geometry, this drill delivers consistent performance in demanding production and maintenance environments. It carries a 17/64 inch diameter tip and a 4 inch depth of cut, with an overall length of 4-1/8 inches. The cobalt-alloyed high-speed steel construction provides increased heat resistance and edge retention when working through tough alloys, stainless steel, and hardened metals. Licensed machinists, maintenance technicians, and industrial tradespeople are the primary installers and operators.

This drill is suited for use in stationary drill presses, handheld electric drills, and CNC drilling applications where hard-surface materials require a more heat-tolerant cutting tool. Typical applications include drilling through stainless steel fastener holes, hard alloy structural components, and similar ferrous metals encountered in industrial and commercial maintenance work. It is sold individually as a single-piece unit.

Key Features

• HSS cobalt construction for superior heat resistance and edge retention in hard materials
• 17/64 inch diameter tip for precision hole sizing
• 4 inch depth of cut supports through-drilling in standard stock thicknesses
• Straight shank design for broad compatibility with standard drill chucks
• Type J heavy-duty jobber length geometry for rigidity and reduced deflection
• 0.6 pound package weight — lightweight for single-piece handling and storage

Compatibility

Designed as an OEM-style heavy-duty jobber drill replacement for use in standard straight-shank drill chucks requiring a 17/64 inch diameter cutting tool.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the drill press or handheld drill is powered down and the chuck is fully secured before beginning work. Use appropriate cutting fluid or coolant when drilling hard alloys to extend tool life and reduce heat buildup. Always wear appropriate eye protection and secure the workpiece before drilling.
