Guhring 9007320040900 Solid Carbide Jobber Drill Bit

Product Description

The GUHRING 9007320040900 is a solid carbide jobber length drill bit in No. 20 wire size (0.1610 inches diameter), designed for precision drilling in general-purpose applications. Built from solid carbide with a bright uncoated finish, this bit delivers consistent performance across a range of non-ferrous and soft materials. It features a 118-degree faceted point angle with web thinning for improved center accuracy and reduced thrust on entry. The overall length is 75 millimeters, and the spiral flute geometry is optimized for efficient chip evacuation during through-hole operations. Licensed tradespeople and machining professionals will find this bit suited to production and maintenance drilling tasks alike.

This drill bit is rated for primary use in aluminum and other N-group non-ferrous materials. With a flute-to-diameter ratio of 5xD and a maximum drilling depth of 36.87 millimeters, it is well matched to standard jobber-length drilling operations in CNC machining centers, drill presses, and hand-held power tools. The straight-cylindrical shank with an h8 diameter tolerance ensures consistent chuck retention across standard toolholding systems. It is sold individually and intended for professional machining environments where dimensional accuracy is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous drilling
• 118-degree faceted point angle with web thinning for accurate entry and reduced thrust
• Bright uncoated finish suitable for aluminum and N-group workpiece materials
• Right-hand spiral flute with regular helix for efficient chip clearing
• Straight-cylindrical shank with h8 tolerance for consistent chuck grip
• DIN specification conformance for dimensional consistency

Compatibility

Designed as a general-purpose jobber length drill bit in No. 20 wire size (0.1610 inches), compatible with standard 3-jaw drill chucks and collet systems that accept a 4.09 millimeter straight-cylindrical shank. Part of the GUHRING Series 732 product line.

Installation Notes

Installation is performed by qualified machinists or tool-and-die professionals. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Power down and lock out the machine spindle before inserting or removing the bit. Do not exceed the recommended maximum drilling depth of 36.87 millimeters for this bit geometry, and use appropriate cutting fluid for the workpiece material where required.
