Guhring 9005490033500 Jobber Drill Bit 3.35mm Hss

Product Description

The GUHRING 9005490033500 is a jobber length drill bit designed for precision drilling in metalworking and general industrial applications. Built from high speed steel with a bright uncoated finish, this bit features a 3.35 mm (0.1319 inch) diameter and a 130-degree split point with web thinning for improved penetration and reduced thrust. The parabolic flute geometry promotes efficient chip evacuation, making it well suited for production drilling where consistent hole quality is required. Overall length is 65 mm (approximately 2-9/16 inches) with a straight-cylindrical shank of matching 3.35 mm diameter. Licensed machinists, maintenance technicians, and tool-room professionals are the primary installers of this bit.

This drill bit is rated as a high performance grade tool optimized for use in aluminum and non-ferrous materials, as indicated by its K, N, and P workpiece material codes. The parabolic flute design with a 5xD flute-to-diameter ratio and a maximum drilling depth of approximately 30.98 mm (1.22 inches) makes it appropriate for through-hole and blind-hole work on CNC machining centers, drill presses, and hand-held industrial drilling equipment. It conforms to DIN 338 standards and is produced under GUHRING Series 549.

Key Features

• 3.35 mm diameter with a tight tolerance of -0.018 to 0.000 mm for consistent hole sizing
• 130-degree standard point with web thinning reduces entry force and improves centering
• Parabolic flute geometry with 5xD ratio supports fast chip evacuation in deep holes
• Bright uncoated high speed steel construction for use across a broad range of materials
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Manufactured to DIN 338 specification for dimensional consistency

Compatibility

Designed as a DIN 338-compliant jobber length drill bit suitable for use in standard drill chucks and collet systems accepting a 3.35 mm straight-cylindrical shank. Optimized for aluminum and non-ferrous workpiece materials per primary workpiece material codes K, N, and P.

Installation Notes

This bit is installed by machinists or maintenance technicians using standard drill chuck or collet toolholding systems; confirm runout and chuck concentricity before use to preserve diameter tolerance. Secure the workpiece firmly before drilling and apply appropriate cutting fluid for the workpiece material to extend tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.
