Guhring 9005490023500 Jobber Drill Bit 2.35mm Hss

Product Description

The GUHRING 9005490023500 is a jobber length drill bit designed for precision drilling in metalworking and light industrial applications. Built from high speed steel with a bright uncoated finish, this bit features a 2.35 mm diameter, a 130-degree drill point angle, and a parabolic flute profile that promotes efficient chip evacuation at depth. The straight-cylindrical shank seats securely in standard drill chucks. Web thinning at the point reduces entry force and heat buildup. This is a high-performance grade bit conforming to DIN 338, suited for machinists, toolroom technicians, and maintenance trades requiring consistent small-diameter hole quality.

This bit is well suited for drilling aluminum and non-ferrous materials, as indicated by its primary workpiece material classification. The parabolic flute geometry with a 5xD flute-to-diameter ratio handles chip clearance effectively in through-hole and blind-hole operations. A maximum drilling depth of 0.924 inches supports typical jobber-length applications in sheet stock, plate, and light structural sections. The overall length of 2-3/32 inches keeps the bit compact and stiff, minimizing deflection on smaller CNC machines, drill presses, and hand-held power drills.

Key Features

• 2.35 mm diameter with a diameter tolerance of -0.014 to 0.000 mm for consistent, repeatable hole size
• 130-degree point angle with web thinning for reduced entry force and clean starts
• Parabolic flute design promotes chip ejection in aluminum and similar materials
• High speed steel construction with bright uncoated finish — no coating to flake or delaminate
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Conforms to DIN 338 for dimensional consistency across interchangeable tooling setups

Compatibility

Designed as an OEM-style jobber length drill bit conforming to DIN 338, compatible with standard drill chucks and collet systems that accept a 0.0925 inch straight shank diameter.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or tool-trained technicians familiar with proper chuck-tightening procedures and feed-rate selection for small-diameter tooling. Always ensure the spindle is fully stopped and the machine is powered down before changing bits. Use appropriate cutting fluid or lubricant when drilling metals to extend tool life and maintain hole tolerance. Do not exceed the recommended maximum drilling depth of 0.924 inches without retracting to clear chips.
