Guhring 9005490016500 Jobber Drill Bit 1.65mm Hss

Product Description

The GUHRING 9005490016500 is a jobber-length twist drill bit engineered for precision hole-making in light-alloy and non-ferrous applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a parabolic flute geometry that promotes efficient chip evacuation and reduces heat buildup during cutting. The 130-degree split point with web thinning allows for self-centering entry and reduces the thrust force needed to start the hole. With an overall length of 43.00 mm (approximately 1-11/16 inches) and a flute length of 20.00 mm (25/32 inches), the 9005490016500 is sized for standard jobber-length drilling tasks. Licensed machinists, maintenance technicians, and metalworking professionals reach for this bit when accuracy and chip control in aluminum and similar materials are the priority.

This drill bit is optimized for primary workpiece materials classified under DIN material codes K, N, and P, which cover aluminum alloys, non-ferrous metals, and some plastics. The 1.65 mm (0.0650 inch) diameter makes it well suited for small-diameter precision holes in sheet stock, castings, and machined components. The straight-cylindrical shank fits standard drill chucks and collet-style toolholders. It conforms to DIN 338 standards, making it a direct fit for applications where DIN-spec tooling is specified. Maximum drilling depth is 17.53 mm (0.6900 inches) based on the 5xD flute-to-diameter ratio of Series 549.

Key Features

• Parabolic flute design for fast chip removal and reduced clogging in aluminum and non-ferrous materials
• 130-degree point angle with web thinning for self-centering starts and lower thrust requirements
• High-speed steel construction with bright uncoated finish, suitable for light-to-moderate duty applications
• Tapered web configuration adds rigidity and reduces bit deflection in small-diameter drilling
• Conforms to DIN 338 specification for consistent interchangeability across DIN-compliant tooling setups
• Right-hand cut, straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a DIN 338-compliant jobber-length drill bit suitable for use in drill presses, CNC machining centers, and hand-held drills where a straight-cylindrical shank is accepted. Primary material compatibility includes aluminum alloys, non-ferrous metals, and plastics per DIN material codes K, N, and P.

Installation Notes

This bit should be installed by qualified machinists or metalworking technicians familiar with cutting tool setup. Secure the shank fully in the chuck or collet before starting the spindle, and verify runout is within acceptable limits for the application. Do not exceed the maximum drilling depth of 17.53 mm in a single pass without retracting to clear chips. Use appropriate cutting fluid or air blast as required by the workpiece material to extend tool life and maintain hole quality.
