Guhring 9006090061000 Carbide Drill Bit 6.1 Mm

Product Description

The GUHRING 9006090061000 is a solid carbide jobber-length drill bit engineered for precision drilling in demanding production environments. Built to DIN 6539 standards, it features a 6.1 mm (0.2402 inch) diameter, a 150-degree drill point angle, and a titanium nitride (TiN) coating that extends tool life by reducing friction and heat buildup at the cutting edge. The three-flute spiral design with web thinning improves chip evacuation and reduces thrust force on entry, making it well-suited for high-cycle CNC drilling operations where consistency and hole quality are critical. Machinists and tooling professionals working in job shops or production facilities are the primary users.

This drill bit is designed for self-centering applications where the 150-degree point angle reduces walking without a separate spot drill. It is appropriate for use in aluminum, non-ferrous metals, and plastics where solid carbide construction and TiN coating provide performance advantages over high-speed steel alternatives. With an overall length of 2.756 inches and a flute length of 1.654 inches, it fits standard CNC machining centers and drill presses with straight-cylindrical shank toolholders sized for a 0.2402-inch shank diameter.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance
• TiN coating reduces friction and extends cutting tool life
• Three-flute spiral design improves chip evacuation over two-flute alternatives
• Web-thinned tapered web configuration lowers entry thrust and improves self-centering
• 150-degree standard point angle enables self-centering without a pilot hole
• Conforms to DIN 6539 specification for consistent geometry and interchangeability

Compatibility

Designed as an OEM-style replacement or direct tooling selection for applications requiring a DIN 6539 compliant jobber-length carbide drill bit in the 6.00 mm to 7.00 mm diameter range with a straight-cylindrical shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per facility LOTO procedures. Verify that the straight-cylindrical shank is fully seated and clamped within the toolholder collet before running. Do not exceed the recommended maximum drilling depth of 1.290 inches (32.85 mm) per pass without chip-clearing withdrawal cycles. Coolant-through is not supported on this bit, so ensure adequate external coolant or air blast is applied to prevent thermal buildup during extended production runs.
