Guhring 9007320062500 Jobber Drill Bit Letter D Carbide

Product Description

The GUHRING 9007320062500 is a solid carbide jobber length drill bit sized to Letter D (0.2461 inches), designed for general-purpose drilling in a shop or field environment. It features a 118-degree faceted drill point, a two-flute regular spiral geometry, and a bright uncoated finish. The overall length is 101 millimeters with a 63-millimeter flute length, giving it the reach typical jobber-length bits require for through-hole and blind-hole work. The straight-cylindrical shank measures 6.25 millimeters in diameter and is machined to an h8 tolerance, making it compatible with standard drill chucks across common machine setups. Web thinning reduces entry force and improves chip evacuation at the cutting tip.

This bit is rated for general-purpose use with a primary workpiece material designation of N, indicating suitability for non-ferrous metals such as aluminum. It fits production drilling, CNC drill press, and hand-held power drill applications where a solid carbide tool is specified over HSS for longer tool life in abrasive or high-cycle operations. The Series 732 designation follows DIN specification standards, which are widely referenced in precision machining environments. Machinists, tool-and-die technicians, and fabricators are the typical end users for this bit in both shop and maintenance settings.

Key Features

• Solid carbide construction for extended tool life versus HSS in non-ferrous and abrasive materials
• 118-degree faceted point with web thinning for reduced entry force and cleaner hole starts
• Two-flute regular spiral geometry promotes efficient chip evacuation
• Bright uncoated finish suits aluminum and other non-ferrous workpiece materials
• Straight-cylindrical shank at h8 tolerance fits standard drill chucks without adapters
• DIN Series 732 specification for consistent dimensional interchangeability

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard drill chucks accepting a 6.25-millimeter straight-cylindrical shank, suitable for CNC machining centers, drill presses, and hand-held power drills where Letter D sizing is specified.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with carbide cutting tool handling. Carbide is brittle — avoid impact loading, side loading beyond design parameters, and dropping the bit on hard surfaces. Secure the shank fully in the chuck to the recommended grip depth before operation, and verify spindle runout is within tolerance to prevent premature tip fracture. Always power down and de-energize the machine before changing tooling.
