Guhring 9007300015900 Screw Machine Drill Bit 0.0626 in

Product Description

The GUHRING 9007300015900 is a stub-length, solid carbide screw machine drill bit designed for precision drilling in high-demand production environments. At 0.0626 inches (1/16 inch) in diameter with a 118-degree faceted point angle, it delivers clean entry and controlled chip evacuation through its two-flute spiral design. Built to DIN 6539 standards from micrograin carbide stock, this bit holds an h8 diameter tolerance and features a web-thinned point for reduced thrust. Machinists and tooling technicians working in production shops, CNC setups, and maintenance applications are the primary installers of this tool.

This drill bit is rated for general-purpose use with aluminum as the primary workpiece material, though its solid carbide construction suits a range of non-ferrous and ferrous applications within the Series 730 product family. The stub or screw machine length format provides added rigidity over jobber-length bits, making it well-suited for close-tolerance work in drill presses, CNC machining centers, and manual milling operations where runout control matters. The straight-cylindrical shank is compatible with standard collets and drill chucks sized for 1.59 mm shank diameter.

Key Features

• Solid micrograin carbide construction for extended tool life in production drilling
• 118-degree faceted point angle with web thinning for reduced entry thrust
• Two-flute regular spiral design for efficient chip evacuation
• Stub length format provides increased rigidity versus jobber-length bits
• h8 diameter tolerance meets DIN 6539 specification for consistent hole sizing
• Bright/uncoated finish — no coating variability affecting dimensional accuracy

Compatibility

Designed as an OEM-style general-purpose stub drill for use in standard collet chucks and drill chucks accepting a straight-cylindrical shank; suited for machining centers, CNC drilling, and manual drill press operations targeting aluminum and similar materials.

Installation Notes

Installation of small-diameter carbide drill bits should be performed by qualified machinists or tooling technicians familiar with runout tolerances and proper collet torque procedures. Ensure the spindle and workholding are fully secured and the machine is at a complete stop before changing tooling. Carbide is brittle — avoid side-loading, impact, or over-clamping the shank. Confirm chuck or collet bore matches the 1.59 mm shank diameter before use to prevent premature tool breakage.
