Guhring 9024630059400 Stub Drill Bit 0.234 in Carbide

Product Description

The GUHRING 9024630059400 is a stub-length (screw machine length) solid carbide drill bit designed for precise, repeatable hole-making in metalworking and machining applications. It carries a 0.234 inch (15/64 inch, Letter A) diameter, a 118-degree faceted point angle, and a web-thinned tip geometry that reduces thrust and improves centering at entry. The two-flute, right-hand spiral configuration evacuates chips efficiently. Built to DIN 6539 standards with a K40 carbide grade, this bit is suited for high-speed CNC and manual drilling operations where tool rigidity and dimensional accuracy are priorities.

This drill bit is rated for general-purpose use with a primary workpiece material of aluminum, though its solid carbide construction and DIN 6539 specification make it appropriate for a range of non-ferrous and light ferrous materials in production environments. The straight-cylindrical shank seats directly in standard drill chucks and collet-style toolholders. The stub-length body provides greater stiffness than jobber-length bits, reducing deflection in short-hole and spot-drilling operations. Maximum drilling depth is 0.752 inches. It is a single-piece, individually packaged bit intended for use in machine shops, production lines, and precision fabrication settings.

Key Features

• Solid carbide K40 grade construction for wear resistance and dimensional stability
• 118-degree faceted point with web thinning for reduced entry thrust and accurate self-starting
• DIN 6539 standard compliance for consistent geometry and interchangeability
• Stub-length body minimizes deflection in short-reach and high-feed applications
• Right-hand, two-flute spiral design promotes chip evacuation in aluminum and similar materials
• Straight-cylindrical shank fits standard drill chucks and ER-style collet holders

Compatibility

Designed as an OEM-style screw machine length drill bit compatible with standard straight-shank drill chucks and collet toolholding systems used in CNC machining centers, drill presses, and manual lathes.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Secure the straight-cylindrical shank fully in the chuck or collet before operation and confirm runout is within acceptable tolerance for the application. Power down and de-energize the machine spindle before changing tooling. Do not exceed the maximum drilling depth of 0.752 inches without retracting to clear chips, and use appropriate cutting fluid or coolant when required by the workpiece material.
