Guhring 9005490046200 Jobber Drill Bit No.14 Hss

Product Description

The GUHRING 9005490046200 is a jobber-length drill bit designed for high-performance drilling in metalworking and fabrication applications. Built from high speed steel with a bright uncoated finish, this bit features a 130-degree split point and a parabolic flute geometry that improves chip evacuation and reduces heat buildup during drilling. It measures 3-5/32 inches overall length with a 1-27/32 inch flute length and a straight-cylindrical shank diameter of 0.1819 inches. Conforming to DIN 338 standards, it is suited for use in hand-held drills, drill presses, and CNC machining centers where wire gauge No. 14 sizing is required. Installation is performed by machinists, fabricators, and maintenance mechanics.

This drill bit is engineered primarily for aluminum and similar non-ferrous and low-alloy workpiece materials, as indicated by the K, N, and P material codes per DIN classification. The parabolic flute profile with a 5xD flute-to-diameter ratio provides efficient swarf removal during through-hole and blind-hole operations. The web-thinned, tapered web configuration reduces thrust force at the cutting tip, making it well suited for production drilling where feed rates and cycle times matter. It ships individually and is available as a single unit, making it practical for service replacement or toolcrib restocking.

Key Features

• No. 14 wire gauge size, 0.1819 inch decimal diameter with a tolerance of -0.018 to 0.000 mm
• 130-degree standard point angle with web thinning for reduced thrust and accurate self-starting
• Parabolic flute geometry with 5xD ratio promotes fast, clean chip evacuation
• High speed steel construction with bright uncoated finish — suitable for aluminum, plastics, and mild steel
• Straight-cylindrical shank fits standard drill chucks without adapters
• Conforms to DIN 338 specification for consistent dimensional accuracy

Compatibility

Designed as a DIN 338-compliant jobber-length drill bit for use in standard 3-jaw drill chucks on hand drills, drill presses, and CNC machining centers. Primary workpiece material codes K, N, and P indicate suitability for aluminum, non-ferrous metals, and non-hardened steels.

Installation Notes

This bit is installed by machinists, tool-and-die technicians, and maintenance mechanics using standard drill chucks. Ensure the chuck jaws are clean and the shank is fully seated before tightening to prevent runout. Always power down and de-energize the machine spindle before changing tooling. Use appropriate cutting fluid or lubricant when drilling to extend tool life and maintain hole tolerance.
