Precision Twist Drill 010314 Hss Cobalt Jobber Drill

Product Description

The PRECISION TWIST DRILL 010314 is a heavy-duty HSS cobalt jobber drill designed for cutting through hard and abrasive surfaces where standard high-speed steel bits fall short. The cobalt alloy composition improves heat resistance and extends tool life when drilling into stainless steel, cast iron, hardened alloys, and similar tough materials. This type J straight-shank drill features a 7/32 inch diameter tip and delivers a depth of cut of 4 inches, making it well suited for through-hole and deep-hole applications in demanding shop and field environments. Licensed tradespeople and machinists rely on this drill for consistent, accurate results on materials that would prematurely wear conventional bits.

This drill is appropriate for use in metalworking, fabrication, HVAC, plumbing rough-in, and electrical trade applications where hard-surface penetration is required. The straight shank accommodates standard three-jaw chucks on corded drills, drill presses, and magnetic base drills. It is packaged as a single unit, making it a practical replacement or addition to a professional tool kit without requiring a full set purchase.

Installation Notes

Installation of this drill bit should be performed by a qualified tradesperson or machinist familiar with drill press and handheld drill safety practices. Secure the shank fully in the chuck and verify tightness before operation to prevent slippage. When drilling hard surfaces, use appropriate cutting fluid or coolant to reduce heat buildup and extend bit life. Always wear eye protection and follow applicable shop safety standards during use.
