Guhring 9003010007600 Micro Drill Bit 0.0299 in Cobalt

Product Description

The GUHRING 9003010007600 is a cobalt micro drill bit engineered for precision drilling in small-diameter applications. It measures 0.0299 inches in diameter with an overall length of 0.984 inches and a maximum drilling depth of 0.164 inches. The 118-degree faceted point with web thinning and tapered web configuration reduces thrust and improves centering on entry. The bright uncoated cobalt construction provides heat resistance suitable for demanding materials. A right-hand spiral flute evacuates chips efficiently during operation. This bit is used by machinists, tool-and-die technicians, and precision fabricators requiring tight dimensional control in micro-diameter work.

This drill bit is suited for production and prototype drilling in aluminum and titanium alloy workpieces, covering material codes K, M, N, P, and S. Its 5xD flute-to-diameter ratio supports controlled chip evacuation in shallow-hole micro drilling operations. The straight-cylindrical shank with a 1.00 mm shank diameter seats directly in standard precision collet chucks or micro drill presses. Series 301 construction conforms to DIN 1899 specification, making it a standard-compliant choice for aerospace, medical device, and precision mechanical applications where consistent hole geometry is critical.

Key Features

• 0.0299-inch diameter cobalt construction for micro-scale drilling applications
• 118-degree faceted drill point with web thinning for reduced entry thrust
• Tapered web configuration improves rigidity at small diameters
• Right-hand spiral flute with regular helix promotes chip clearance
• Diameter tolerance of +0.000 to -0.004 mm supports tight-tolerance hole requirements
• Conforms to DIN 1899 specification, Series 301

Compatibility

Designed for drilling aluminum (K, M, N, P material codes) as the primary workpiece material and titanium alloy (S material code) as the secondary workpiece material. Compatible with standard precision collet chucks and micro drill presses accepting a 1.00 mm straight-cylindrical shank.

Installation Notes

Secure the shank in a precision collet chuck rated for micro-diameter tooling and verify runout before drilling. Ensure the spindle and workpiece are properly fixtured to prevent deflection, which can cause bit breakage at this diameter. Coolant-through is not supported on this bit, so apply external cutting fluid appropriate for the workpiece material when required. Handle micro drill bits carefully to avoid tip damage during storage and changeover.
