Guhring 9014520063000 Carbide Jobber Drill Bit 6.3 Mm

Product Description

The GUHRING 9014520063000 is a solid carbide jobber length drill bit engineered for precision drilling in demanding applications. Built from submicron-grade carbide with a bright uncoated finish, this bit features a 6.3 mm (0.2480 inch) diameter, a 150-degree point angle, and a three-flute spiral configuration. The web-thinned, tapered web geometry promotes self-centering entry and reduces thrust force at the start of cut. With an overall length of 70 mm (2.7559 inches) and a flute length of 42 mm (1.6535 inches), it fits standard straight-cylindrical shank toolholders. It is installed and operated by machinists and tool-room technicians working in production and maintenance environments.

This drill bit is suited for applications requiring tight hole-location accuracy and clean entry without a center punch or pilot hole, owing to its self-centering point geometry. The 5xD flute-to-diameter ratio allows drilling to a maximum depth of 32.55 mm (1.28 inches) in a single pass. Series 1452 bits in this size range (6.00 mm to 7.00 mm) are commonly selected for ferrous and non-ferrous materials where carbide hardness and rigidity outperform high-speed steel alternatives. Dry or mist-lubricated cutting is typical, as this bit does not incorporate through-coolant capability.

Key Features

• Submicron solid carbide construction for high hardness and wear resistance
• 150-degree point angle with self-centering geometry eliminates need for a pilot hole
• Three-flute spiral design improves chip evacuation and hole-finish quality
• Web-thinned tapered web reduces cutting thrust and entry force
• Bright uncoated finish maintains sharp edge geometry without coating buildup
• Conforms to DIN 6539 standard for dimensional and geometric accuracy

Compatibility

Designed as an OEM-style replacement or direct-fit tooling selection for standard straight-cylindrical shank toolholders accepting a 0.2480 inch (6.3 mm) shank diameter, consistent with DIN 6539 specifications.

Installation Notes

This bit is installed by machinists in drill presses, CNC machining centers, or hand-held drilling equipment with a compatible chuck or collet rated for the shank diameter. Ensure the spindle and workpiece are secured before operation. Do not exceed the rated maximum drilling depth of 32.55 mm in a single pass without retracting to clear chips. No through-coolant is available on this bit, so external lubrication or dry cutting practices should be applied according to the workpiece material requirements.
