Guhring 9024630022600 Solid Carbide Stub Drill Bit 0.089in

Product Description

The GUHRING 9024630022600 is a stub-length, solid carbide screw machine drill bit designed for precision hole-making in tight-clearance applications. It measures 0.089 inches (Wire Size #43) in diameter and features a 118-degree faceted point angle with a web-thinned tip for improved centering and reduced thrust. The two-flute spiral configuration provides efficient chip evacuation, and the straight-cylindrical shank seats securely in standard drill chucks and CNC collets. At 1.575 inches overall length and a flute length of 0.512 inches, this bit is built for rigid setups where shorter overhang and reduced deflection matter. It is suited for machinists, tool-and-die technicians, and precision fabricators working on production or prototype drilling operations.

This drill bit is rated for general-purpose drilling with a primary workpiece material designation of aluminum, though its solid carbide construction and DIN 6539 specification make it appropriate for other non-ferrous and light ferrous materials in controlled machining environments. The stub-length body keeps vibration minimal at small diameters, making it a reliable choice for CNC machining centers, drill presses, and screw machine setups where hole location accuracy is critical. Maximum drilling depth is 0.378 inches, consistent with the 3xD flute-to-diameter ratio of the Series 2463 design.

Key Features

• Solid carbide construction, Material Grade K40, for wear resistance and dimensional stability
• 118-degree faceted point with web thinning for accurate starting and reduced feed force
• Two spiral flutes with regular helix for efficient chip removal
• Stub (screw machine) length at 1.575 inches overall for rigid, low-deflection setups
• Straight-cylindrical shank compatible with standard collets and drill chucks
• Conforms to DIN 6539 specification for consistent geometry and interchangeability

Compatibility

Designed as an OEM-specification replacement or direct-use drill bit conforming to DIN 6539, Series 2463, suitable for standard straight-shank drill chucks and collet holders accepting a 2.26 mm (approximately 0.089 inch) shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Ensure the drill chuck or collet is clean and properly torqued before use, as runout at small diameters accelerates breakage. Power down and lock out all spindle drives before changing tooling. Avoid hand-feeding at excessive rates; carbide is brittle and small-diameter bits are susceptible to breakage under side load or shock.
