Guhring 9007300037300 Carbide Drill Bit 0.147in Wire 26

Product Description

The GUHRING 9007300037300 is a solid carbide, screw machine length (stub) drill bit designed for precision drilling in demanding production environments. Built to DIN 6539 standards, it features a micrograin carbide construction that provides edge retention and dimensional accuracy across extended use cycles. The 118-degree faceted point with web thinning reduces entry thrust, and the two-flute spiral design promotes efficient chip evacuation. At 0.147 inches in diameter (Wire Size 26), this bit is sized for close-tolerance work in light metals and is installed by machinists, tool-and-die technicians, and maintenance professionals running CNC or manual drilling operations.

This stub-length drill bit is suited for short-reach drilling applications where rigidity and runout control are critical. Its straight-cylindrical shank seats directly into standard drill chucks and collet holders without adapters. The bright, uncoated finish makes it a reliable choice for aluminum and other non-ferrous materials where coated tools may cause material adhesion. It is appropriate for general-purpose production drilling in both shop and field maintenance settings where a compact, stiff drill profile is preferred over jobber-length alternatives.

Key Features

• Solid micrograin carbide construction for superior wear resistance and edge stability
• 118-degree faceted drill point with web thinning for reduced entry force
• Two-flute regular spiral flute geometry promotes consistent chip removal
• Bright/uncoated finish optimized for aluminum and non-ferrous workpiece materials
• Stub (screw machine) length provides increased rigidity and reduced deflection
• Manufactured to DIN 6539 specification with h8 diameter tolerance for close-fit work

Compatibility

Designed as a general-purpose stub-length drill bit for use in standard drill chucks and collet systems accepting a 3.73 mm straight-cylindrical shank. Primary workpiece material designation is aluminum; suitable for general-purpose non-ferrous drilling applications per Series 730 specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Ensure the drilling machine spindle is fully stopped and de-energized before changing tooling. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet to the manufacturer-recommended clamping method to prevent pullout. Do not exceed the recommended maximum drilling depth of 0.567 inches for this stub-length geometry.
