Precision Twist Drill 010332 Hss Cobalt Jobber Drill 1/2 in

Product Description

The PRECISION TWIST DRILL 010332 is a heavy-duty, high-speed steel (HSS) cobalt jobber drill designed for cutting through hard surfaces that standard HSS bits cannot handle reliably. It features a straight shank and Type J jobber geometry, with a 1/2 inch tip diameter, a 4 inch depth of cut, and an overall length of 6 inches. The cobalt alloy construction increases heat resistance, making this drill suitable for stainless steel, cast iron, hardened alloys, and other tough materials encountered in industrial and trade applications. It is sold as a single unit.

This drill is suited for metal fabrication shops, mechanical contractors, plumbers, and electricians who need to bore through hard ferrous and non-ferrous materials on the job site or in the shop. The 1/2 inch diameter and 4 inch depth of cut make it appropriate for through-hole and deep-hole drilling in structural steel, pipe flanges, and heavy plate work where a standard jobber drill would overheat or wear prematurely.

Key Features

• HSS cobalt construction for extended tool life in hard and abrasive materials
• Type J straight-shank jobber design compatible with standard 1/2 inch drill chucks
• 4 inch depth of cut for through-hole and deep-hole applications
• 6 inch overall length provides reach in confined or deep work areas
• Heavy-duty designation for use on hard surfaces where standard HSS bits are inadequate

Compatibility

Designed as a straight-shank jobber drill compatible with any 1/2 inch keyed or keyless drill chuck used in corded drills, drill presses, and magnetic base drills.

Installation Notes

Installation of this drill bit should be performed by a qualified tradesperson familiar with metal drilling practices. Secure the shank fully in the chuck and verify chuck tightness before operation. Use appropriate cutting fluid or coolant when drilling hard alloys to reduce heat buildup and extend bit life. Always wear appropriate eye protection and secure the workpiece before drilling.
