Guhring 9006590024400 Cobalt Stub Drill Bit 0.096 in

Product Description

The GUHRING 9006590024400 is a cobalt screw machine length stub drill bit engineered for demanding metalworking applications. Built to DIN 1897 standards, it carries a 0.096 inch (Wire Size 41) diameter with a 130-degree split point and a parabolic flute geometry. The two-flute parabolic design promotes faster chip evacuation and reduced heat buildup. Web thinning lowers entry resistance and helps maintain accuracy in harder workpiece materials. Overall length is 43 mm with a flute length of 14 mm. This bit is intended for use by machinists, tool-and-die professionals, and precision fabricators working in production environments where tight tolerances are critical.

This stub drill bit is rated for cutting titanium alloy as its primary workpiece material, making it suitable for aerospace, medical device, and precision manufacturing applications where high-strength alloys are common. The right-hand cut and straight-cylindrical shank make it compatible with standard drill chucks, CNC machining centers, and drill press setups. Its stub length format provides added rigidity compared to jobber-length bits, reducing deflection in shallow-hole operations. Maximum drilling depth is 0.407 inches (10.34 mm), and the flute-to-diameter ratio is 3xD.

Key Features

• Cobalt construction for heat and wear resistance in hard and abrasive alloys
• 130-degree point angle with web thinning for reduced thrust and cleaner entry
• Parabolic flute profile improves chip flow and lowers cutting torque
• DIN 1897 stub length format increases rigidity and reduces deflection
• Diameter tolerance held to +0.000 to -0.014 mm for precise hole sizing
• Right-hand cut with straight-cylindrical shank fits standard chucks and collets

Compatibility

Designed as a DIN 1897 stub-length drill bit with a straight-cylindrical shank, this bit fits standard drill chucks, ER collets, and CNC tool holders accepting a 0.096 inch shank. Primary workpiece material rating is titanium alloy; the cobalt grade also handles stainless steel and other high-strength materials in general machining practice.

Installation Notes

Installation and use should be performed by qualified machinists following shop safety protocols. Secure the shank fully in the chuck or collet and verify runout before drilling. Power down the machine and lock out energy sources before changing tooling. Do not exceed the rated maximum drilling depth of 0.407 inches per pass without retracting to clear chips.
