Precision Twist Drill 5996356 Jobber Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5996356 is a jobber length drill bit designed for precision drilling in demanding trade applications. Manufactured from M2 high speed steel with a purple/bronze coating, this bit measures 11/32 inch (0.3438 inch) in diameter with a 4-3/4 inch overall length. The 135-degree split point reduces walking and cutting pressure at the tip, making it well suited for production drilling in harder materials. A web-thinned, tapered web configuration further reduces thrust force during entry. This bit is installed by machinists, maintenance technicians, and fabricators working across industrial and field environments.

The 5996356 is intended for drilling into steel, stainless steel, cast iron, superalloys, and titanium. It performs in both handheld drill applications and drill press setups where consistent hole quality is required. With a 10xD flute-to-diameter ratio and a 3-7/16 inch flute length, it provides adequate chip evacuation across typical material thicknesses encountered in metal fabrication, HVAC equipment assembly, and mechanical service work. The straight cylindrical shank fits standard drill chucks without modification.

Key Features

• M2 high speed steel construction for durability in ferrous and hard alloy materials
• 135-degree split point reduces bit walking and lowers entry thrust
• Purple/bronze coating provides lubricity and surface hardness for extended tool life
• Web-thinned tapered web reduces cutting resistance and heat buildup
• Right-hand cut with regular spiral flutes for efficient chip removal
• Meets ANSI standards for jobber length drill bit geometry

Compatibility

Part of the Series HX10-HX15-HX18 line. Designed as a general-purpose jobber length drill bit compatible with any standard drill chuck accepting an 11/32 inch straight cylindrical shank. Suitable for drilling steel, stainless steel, cast iron, superalloys, and titanium as noted by Primary Workpiece Material Codes P, M, K, and S.

Installation Notes

This drill bit is installed by machinists, HVAC technicians, plumbers, and general maintenance trades using a handheld drill or drill press. Always secure the workpiece before drilling and use appropriate cutting fluid when drilling stainless steel, cast iron, or titanium to manage heat. Inspect the cutting edge for wear before each use and replace if chipping or dulling is observed. Follow applicable shop safety and PPE requirements when operating rotary cutting tools.
