Guhring 9007320079400 Jobber Drill Bit 5/16 in Carbide

Product Description

The GUHRING 9007320079400 is a solid carbide jobber length drill bit designed for precision drilling in general-purpose and aluminum-focused applications. Built to DIN specification, the Series 732 bit features a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry force and improves centering. The bright, uncoated finish suits non-ferrous materials where coating adhesion or heat buildup is not a primary concern. At 117 mm overall length with a 75 mm flute length, this bit fits standard drill chucks and CNC setups. Machinists and trade technicians working with aluminum, plastics, and similar N-group materials reach for this bit when dimensional accuracy and chip evacuation matter.

The Series 732 is suited for drilling aluminum and other non-ferrous or non-metallic materials in both manual and CNC-driven operations. The straight-cylindrical shank with a 7.94 mm diameter and h8 tolerance fits precision tool holders and standard drill chucks without modification. The regular spiral flute design at a 5xD flute-to-diameter ratio provides consistent chip evacuation across the 63.09 mm maximum drilling depth. This bit is a solid choice for production shops, maintenance technicians, and fabricators working with light-metal components.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous materials
• 118-degree faceted point angle for clean entry and accurate hole positioning
• Web-thinned geometry reduces thrust force and improves self-centering
• Bright, uncoated finish optimized for aluminum and N-group workpiece materials
• Straight-cylindrical shank at h8 tolerance for precise tool-holder fit
• DIN specification, Series 732 — consistent geometry for repeatable results

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard drill chucks and CNC tool holders accepting a 0.3126-inch straight-cylindrical shank. Rated for aluminum and other primary workpiece materials designated under N-group classification.

Installation Notes

Installation and use should be performed by qualified machinists or trade technicians familiar with drill press, mill, or CNC operation. Ensure the spindle is fully stopped and the machine is powered down before changing or seating the bit in the chuck or tool holder. Confirm the shank is fully seated and the chuck or collet is tightened to manufacturer specification before beginning any drilling operation. Carbide tooling is brittle — avoid side loads, interrupted cuts without appropriate feed adjustments, and dropping the bit on hard surfaces.
