Guhring 9005490026400 Jobber Drill Bit No.37 Hss

Product Description

The GUHRING 9005490026400 is a wire gauge No. 37 jobber length drill bit manufactured to DIN 338 standards from high speed steel with a bright uncoated finish. The bit measures 0.1039 inches in diameter and carries an overall length of 2.25 inches, with a parabolic flute length of 1.1875 inches. The 130-degree split point with web thinning reduces entry thrust and improves chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. This is a high-performance grade bit suited to production and maintenance drilling in metal fabrication, mechanical contracting, and general trade applications.

The 9005490026400 is optimized for primary workpiece materials classified under DIN material codes K, N, and P, which cover aluminum alloys, non-ferrous metals, and general-purpose steels. The parabolic flute geometry with a 5xD flute-to-diameter ratio promotes efficient chip removal in through-hole and blind-hole drilling. Maximum drilling depth is 1.025 inches (26.04 mm). The right-hand cutting direction is standard for conventional drill press, hand drill, and CNC spindle use. Licensed trades including machinists, HVAC installers, plumbers, and electricians use jobber bits of this type for sheet metal, structural, and equipment-mounting hole work.

Key Features

• Wire gauge No. 37 diameter: 0.1039 inches, conforming to DIN 338
• 130-degree standard point angle with web thinning for reduced entry force
• Parabolic flute geometry at 5xD ratio for efficient chip clearance
• High-performance grade high speed steel with bright uncoated finish
• Straight-cylindrical shank compatible with standard chuck sizes
• Right-hand cut, two-flute design for general-purpose drilling

Compatibility

Designed as an OEM-style jobber length drill bit for use in standard three-jaw drill chucks, keyless chucks, and CNC tool holders accepting a 0.1039-inch straight-cylindrical shank.

Installation Notes

Install and remove drill bits only when the drill press, hand drill, or CNC spindle is fully de-energized and at rest. Secure the shank fully in the chuck and verify runout before drilling. Eye protection and appropriate work-holding are required per standard shop safety practice. Do not exceed the rated maximum drilling depth of 1.025 inches without retracting to clear chips.
