Precision Twist Drill 5997024 Jobber Drill Bit Wire 6

Product Description

The PRECISION TWIST DRILL 5997024 is a jobber-length drill bit sized to wire gauge number 6, with a decimal diameter of 0.2040 inches. Built from high-speed steel with a bright uncoated finish, it features a 135-degree split point for self-centering starts and reduced walking on hard surfaces. The parabolic spiral flute geometry promotes efficient chip evacuation during drilling. With an overall length of 3.75 inches and a flute length of 2.5 inches, this bit suits general-purpose drilling tasks in metal fabrication, maintenance, and repair environments. It is installed by machinists, millwrights, and general tradespeople working with ferrous and non-ferrous materials.

This drill bit is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is appropriate for use in hand drills, drill presses, and CNC drilling applications where a straight-cylindrical shank is acceptable. The QC21P series is rated as heavy-duty and general-purpose, making it suitable for both production environments and field repair work. Maximum drilling depth is 2.5 inches, consistent with the full flute length. No coolant-through capability is provided.

Key Features

• Wire gauge number 6 size, 0.2040 inch decimal diameter, for precise hole sizing
• 135-degree split point reduces thrust and self-centers on the workpiece
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Parabolic spiral flute with web-thinned, tapered web for improved chip clearance
• Straight-cylindrical shank, 0.2040 inch diameter, compatible with standard chucks
• Meets ANSI standards; heavy-duty grade rating

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill press, hand drill, or CNC spindle accepting a straight-cylindrical shank. Suitable for workpieces classified under material codes P, M, K, N, and S, covering steel, stainless steel, cast iron, non-ferrous metal, and superalloys.

Installation Notes

Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Use cutting fluid or coolant on the workpiece surface when drilling hardened steels or stainless steel to extend bit life, as this bit does not provide internal coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace if the point is damaged to maintain hole quality and prevent workpiece damage.
