Precision Twist Drill 5998116 Jobber Drill Bit 33 Hss

Product Description

The PRECISION TWIST DRILL 5998116 is a jobber-length drill bit in wire gauge size 33, with a decimal diameter of 0.113 inches. Manufactured from high speed steel with a bright uncoated finish, it features a standard 118-degree split point and a regular spiral flute for consistent chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. With an overall length of 2.625 inches and a flute length of 1.5 inches, this bit is designed for general-purpose drilling in ferrous and non-ferrous materials. It is sized and built for everyday production use by machinists, pipefitters, and sheet metal tradespeople.

This drill bit is suited for drilling through steel, cast iron, non-ferrous metals, superalloys, and titanium in light to medium-duty applications. The 13xD flute-to-diameter ratio and tapered web with web thinning reduce thrust requirements and help maintain hole accuracy on manual drill presses, drill motors, and CNC lathes where a right-hand cutting direction is required. The ANSI-standard geometry makes it a direct fit in any shop or field kit stocking wire-gauge tooling in the 0.100 to 0.150 inch range.

Key Features

• Wire gauge size 33 with 0.113 inch decimal diameter for precise hole sizing
• 118-degree standard point angle with web thinning to reduce entry thrust
• High speed steel construction for durability across ferrous and non-ferrous workpieces
• Bright uncoated finish compatible with cutting fluids and standard HSS re-sharpening practices
• Regular spiral, 2-flute design for efficient chip evacuation in through-hole drilling
• ANSI-standard geometry for consistent fitment with standard drill chucks and holders

Compatibility

Designed as a general-purpose jobber-length replacement in wire gauge drill sets covering the 0.100 to 0.150 inch decimal range. Compatible with primary workpiece materials coded P (steel), K (cast iron), N (non-ferrous metal), and S (superalloys and titanium) per ISO material classification.

Installation Notes

Installation is performed by machinists, maintenance technicians, or sheet metal tradespeople using a standard drill press, hand drill, or CNC spindle. Ensure the straight shank is fully seated and the chuck is tightened securely before operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Inspect the drill point for wear or chipping before each use and re-sharpen or replace as needed.
