Guhring 9007320031000 Solid Carbide Jobber Drill Bit 3.1mm

Product Description

The GUHRING 9007320031000 is a solid carbide jobber-length drill bit designed for general-purpose drilling in a wide range of materials, with a primary application in aluminum and other non-ferrous metals. It measures 3.1 mm (0.1220 inches) in diameter with an overall length of 65 mm and a flute length of 36 mm. The 118-degree faceted point provides accurate self-starting entry, while the web-thinned, tapered web geometry reduces thrust and improves chip evacuation. The bright, uncoated finish is standard for carbide tooling used in non-ferrous applications where coating adhesion is not required. This bit is sold individually and suits machinists, tool-and-die shops, and maintenance technicians working with precision drilling requirements.

This drill bit is suited for production and maintenance drilling in aluminum, non-ferrous metals, and similar workpiece materials classified under material grade N. The Series 732 designation places it in a general-purpose carbide jobber line with a 5xD flute-to-diameter ratio, allowing drilling depths up to approximately 31.35 mm (1.234 inches). The straight-cylindrical shank fits standard drill chucks and collet systems without modification, making it compatible with CNC machining centers, drill presses, and hand-held pneumatic or electric drill motors.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in non-ferrous materials
• 118-degree faceted drill point with web thinning for reduced entry thrust
• Tapered web configuration with 2 spiral flutes for efficient chip removal
• Bright, uncoated finish optimized for aluminum and material grade N workpieces
• Right-hand cut with regular spiral type for standard drilling operations
• Straight-cylindrical shank compatible with standard chucks and collet systems

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks and collet holders accepting a 0.1220-inch straight-cylindrical shank, suitable for CNC and manual drilling equipment.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard toolholding equipment. Ensure the chuck or collet is clean and properly tightened before operation. Use appropriate cutting fluid or coolant recommendations for the workpiece material even though this bit does not feature through-coolant capability. Inspect the cutting edge for wear or chipping before each use, as carbide tooling can fracture if run in an improperly supported workpiece or at incorrect feed and speed parameters.
