Guhring 9005490146800 Jobber Drill Bit 37/64 in Hss

Product Description

The GUHRING 9005490146800 is a jobber length drill bit designed for high-performance metal cutting in professional machining and fabrication applications. Built from high speed steel with a bright uncoated finish, this bit features a parabolic flute geometry that improves chip evacuation and reduces heat buildup during drilling. The 130-degree point angle and web-thinned tip provide clean entry and reduced thrust force. With an overall length of 6-5/8 inches and a flute length of 4-1/2 inches, it handles drilling depths up to 3.621 inches. Right-hand cut geometry and a straight-cylindrical shank make it compatible with standard drill chucks and CNC spindles alike.

This drill bit is intended for use in machine shops, fabrication facilities, and job sites where consistent, accurate hole production is required. It is rated as a high-performance tool primarily suited for aluminum and non-ferrous materials, as indicated by its K, N, and P workpiece material codes per DIN 338 classification. The Series 549 designation and 5xD flute-to-diameter ratio make it well suited for general-purpose jobber drilling on both manual and CNC equipment. Machinists, tool-and-die technicians, and production operators will find this bit appropriate for medium to high-volume drilling operations.

Key Features

• Parabolic flute design improves chip removal and reduces heat in the cut zone
• 130-degree point angle with web thinning reduces entry thrust and improves centering
• High speed steel construction provides durability across a range of non-ferrous and soft ferrous materials
• Bright uncoated finish allows for easy visual wear inspection
• Straight-cylindrical shank fits standard three-jaw drill chucks and CNC collets
• Manufactured to DIN 338 specification for consistent dimensional tolerancing

Compatibility

Conforms to DIN 338 standards and is classified under Series 549 with a primary workpiece material designation of K, N, and P, covering aluminum, non-ferrous metals, and long-chipping materials. Designed for use in standard drill chucks and CNC spindles accepting a 37/64 inch straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with proper speeds and feeds for high speed steel tooling. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Do not exceed the recommended maximum drilling depth of 3.621 inches without retracting to clear chips. Coolant-through is not supported on this bit; apply external cutting fluid appropriate for the workpiece material when required.
