Precision Twist Drill 5996326 Jobber Drill Bit 1/8 in

Product Description

The PRECISION TWIST DRILL 5996326 is a jobber-length drill bit designed for general-purpose drilling in metal and metal-adjacent materials. Built from high speed steel with a bronze bright coating, the bit features a 135-degree split point and a web-thinned, tapered web configuration that reduces thrust and improves centering on entry. The straight-cylindrical shank measures 0.125 inches in diameter, matching the 1/8 inch drill diameter. Overall length is 2.75 inches with a flute length of 1.625 inches, making it suited for standard-depth through-hole and blind-hole work in shop and field environments.

This bit is part of the PRECISION TWIST DRILL HX10-HX15-HX18 series and is built for drilling steel, stainless steel, cast iron, superalloys, and titanium. It is a common choice for HVAC, plumbing, and mechanical contractors drilling sheet metal, structural steel, and pipe hangers. The 2-flute spiral geometry provides efficient chip evacuation during through-hole drilling. No coolant-through capability is present, so external lubrication or cutting fluid is recommended when drilling harder alloys or stainless steel to extend tool life.

Key Features

• 135-degree split point reduces walking and lowers drilling thrust
• Web-thinned, tapered web improves penetration in hard metals
• High speed steel construction handles steel, stainless steel, cast iron, superalloys, and titanium
• Bronze bright coating provides mild lubricity and corrosion resistance during storage
• 2-flute regular spiral geometry promotes clean chip evacuation
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw drill chuck or keyed chuck accepting a 1/8 inch straight shank. Meets ANSI specification standards. Part of the HX10-HX15-HX18 series.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade contractors using corded or cordless drills and drill presses. Secure the shank fully in the chuck and verify concentricity before drilling. When working with stainless steel, superalloys, or titanium, apply cutting fluid to reduce heat buildup and extend bit life. Follow applicable shop safety practices including eye protection and workpiece fixturing.
