Chicago-latrobe 44283 Jobber Drill Bit No. 13 Hss 118

Product Description

The CHICAGO-LATROBE 44283 is a jobber-length drill bit from the Series 150D line, manufactured from high speed steel with a bright, uncoated finish. Sized at wire gauge No. 13 (0.1850 inches decimal), it features a 118-degree standard point angle and a two-flute regular spiral design for efficient chip evacuation. The straight-cylindrical shank measures 0.1850 inches in diameter, and the overall length is 3.5 inches with a flute length of 2.3125 inches. The web-thinned, tapered web configuration reduces cutting resistance at entry, making it a practical choice for general-purpose drilling in production and maintenance environments.

This drill bit is suited for drilling non-ferrous metals and general-purpose materials in light manufacturing, maintenance, and fabrication applications. The right-hand cutting direction and regular spiral geometry make it compatible with standard bench drill presses, hand drills, and CNC drilling operations. It conforms to DIN 338 standards, which specify jobber-length geometry and tolerances commonly referenced in industrial tooling specifications. Licensed machinists, tool-and-die technicians, and maintenance mechanics will find this bit a straightforward drop-in for standard No. 13 wire gauge applications.

Key Features

• Wire gauge No. 13 sizing at 0.1850 inches decimal diameter
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust
• High speed steel construction rated for general-purpose and non-ferrous metal drilling
• Bright, uncoated finish — no coating to flake or chip under heavy use
• Right-hand, two-flute regular spiral for reliable chip clearing
• DIN 338 compliant jobber-length geometry
• Straight-cylindrical shank fits standard drill chucks without adaptation

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to DIN 338 standards, suitable for use in any standard drill chuck accepting a 0.1850-inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists, tool-and-die technicians, or maintenance personnel using standard drill press or hand drill equipment. Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation. Always power down and de-energize the machine before changing tooling. Ensure workpiece is properly clamped and use appropriate cutting fluid for the workpiece material when operating at higher speeds.
