Guhring 9005490055600 Jobber Drill Bit 7/32 in Hss

Product Description

The GUHRING 9005490055600 is a jobber length drill bit engineered for high-performance drilling in a wide range of materials. Built from high speed steel with a bright uncoated finish, this bit measures 7/32 inch (0.2188 inch decimal) in diameter with an overall length of 3-21/32 inches and a flute length of 2-1/4 inches. The 130-degree split point and parabolic flute geometry work together to reduce walking, improve chip evacuation, and maintain cutting efficiency through the full depth of the hole. A web-thinned, tapered web configuration lowers the thrust required at entry. This bit is suited for machinists, tool and die tradespeople, and HVAC or fabrication professionals who need consistent, repeatable results in production or service environments.

The 9005490055600 is rated for primary use in aluminum and non-ferrous materials, as well as plastics and some ferrous stock, corresponding to workpiece material codes K, N, and P. The straight-cylindrical shank fits standard 3-jaw chucks and drill presses without adapters. With a maximum drilling depth of 1.916 inches and a flute-to-diameter ratio of 5xD, this bit handles typical through-hole and spot-drilling tasks on sheet metal, extrusion stock, and structural profiles. It is sold individually and is appropriate for both bench drilling and handheld drill applications in shop or field settings.

Key Features

• High speed steel construction with bright uncoated finish for general-purpose cutting
• 130-degree drill point angle reduces walking and improves entry accuracy
• Parabolic flute geometry promotes fast, efficient chip evacuation
• Web-thinned tapered web lowers thrust requirements at drill entry
• Right-hand cut with straight-cylindrical shank for universal chuck compatibility
• Conforms to DIN 338 standard for consistent dimensional tolerances

Compatibility

Designed as a DIN 338-compliant jobber length drill bit for use in standard 3-jaw chucks, drill presses, and CNC machining centers. Primary workpiece materials are aluminum, non-ferrous metals, and plastics (material codes K, N, P).

Installation Notes

Installation is performed by machinists or trade professionals using standard drill press, hand drill, or CNC equipment. Secure the straight-cylindrical shank fully in the chuck before operation and verify chuck key removal before starting the spindle. Drilling depth should not exceed the rated maximum of 1.916 inches without retracting to clear chips. Always wear appropriate eye protection and secure the workpiece before drilling.
