Guhring 9003290015100 Drill Bit Size 53 Cobalt

Product Description

The GUHRING 9003290015100 is a stub-length (screw machine length) cobalt drill bit in wire gauge size 53, with a decimal diameter of 0.0595 inches. Built to DIN 1897 standards, it features a 130-degree split point and web-thinned geometry that reduces walking and cutting resistance at entry. The overall length is 34 millimeters (1.3386 inches), keeping the tool rigid in short-reach drilling applications. Two spiral flutes channel chips efficiently, and the bright uncoated finish suits cobalt alloy construction without adding coating thickness that could affect tolerance. Licensed machinists and tool-and-die professionals are the primary users of this bit.

This bit is designed for drilling titanium alloy and other tough materials where a standard high-speed steel bit would wear prematurely. The stub-length body reduces deflection in CNC machining centers, drill presses, and manual machines where a shorter stick-out is required. The straight-cylindrical shank diameter of 0.0594 inches fits standard collets and drill chucks. Maximum drilling depth is 7.74 millimeters (0.305 inches), consistent with the 3xD flute-to-diameter ratio. Series 329 identifies the Guhring product line this bit belongs to.

Key Features

• Cobalt construction for heat resistance in titanium alloy and hard material drilling
• 130-degree point angle with web thinning reduces thrust force and prevents walking
• Stub-length body (34 millimeters OAL) minimizes deflection in tight-reach setups
• DIN 1897 specification ensures dimensional consistency and interchangeability
• Bright uncoated finish preserves diameter tolerance of +0.000 to -0.014 millimeters
• Right-hand cutting, 2-flute spiral design for efficient chip evacuation

Compatibility

Designed as an OEM-specification stub-length drill bit compatible with standard straight-shank collets and drill chucks accepting a 0.0594-inch shank diameter, conforming to DIN 1897 for screw machine length tooling.

Installation Notes

Installation and use of this bit should be performed by qualified machinists familiar with drill press, CNC machining center, or manual lathe operations. Secure the straight-cylindrical shank fully in the collet or chuck before operation and verify runout is within acceptable limits for the application. When drilling titanium alloy, use appropriate cutting fluid to manage heat and extend tool life. Inspect the cutting edges for wear before each use and replace the bit when point geometry is degraded.
