Guhring 9003290054100 Cobalt Drill Bit 0.2130 in 130 Deg

Product Description

The GUHRING 9003290054100 is a cobalt screw machine length (stub length) drill bit designed for high-performance drilling in tough materials. Built to DIN 1897 standards, this Series 329 bit features a 0.2130 inch (wire size No. 3) diameter with a 130-degree split point for aggressive penetration and reduced walking on hard surfaces. The web-thinned, parallel-web construction lowers thrust requirements and extends tool life. With an overall length of 2.5984 inches and a flute length of approximately 1.102 inches, this compact geometry suits short-reach drilling applications in machine shop and production environments. Machinists and tooling professionals install this bit in drill presses, CNC machining centers, and hand-held production tooling.

This stub-length cobalt drill bit is suited for drilling titanium alloy and other high-strength, work-hardening materials where standard high-speed steel bits underperform. The 130-degree point angle and web thinning are specifically matched to harder workpiece materials. Its straight cylindrical shank fits standard drill chucks without modification. The short flute-to-diameter ratio of 3xD and maximum drilling depth of 0.7830 inches make it a reliable choice for through-hole and blind-hole operations in production machining setups where rigidity and repeatability matter.

Key Features

• Cobalt tool material for heat resistance and durability in hard and abrasive workpiece materials
• 130-degree split point reduces thrust and minimizes bit walk on entry
• Web-thinned parallel-web construction lowers cutting force requirements
• Stub length (screw machine length) geometry increases rigidity and reduces deflection
• Right-hand cut with regular spiral flute for consistent chip evacuation
• Manufactured to DIN 1897 specification for dimensional consistency

Compatibility

Designed as an OEM-style production drill bit for use in standard drill chucks accepting straight cylindrical shanks. Primary workpiece material designation is titanium alloy; cobalt construction is also appropriate for stainless steel, hardened steel, and similar high-strength materials in machining applications.

Installation Notes

Installation is performed by machining professionals in machine shop or production environments. Secure the straight shank fully in the drill chuck and verify concentricity before use. Apply appropriate cutting fluid or coolant at the workpiece when drilling titanium alloy or other work-hardening materials to manage heat buildup. Follow facility safety protocols and machine manufacturer guidelines for spindle speeds and feed rates appropriate to this diameter and workpiece material.
