Guhring 9007320048500 Solid Carbide Jobber Drill Bit

Product Description

The GUHRING 9007320048500 is a solid carbide jobber-length drill bit designed for precise, consistent hole-making in non-ferrous and general-purpose applications. Carrying a wire gauge size of 11 and a decimal diameter of 0.1909 inches, this bit features a 118-degree faceted point angle and a web-thinned tip that reduces entry force and improves centering. The spiral flute geometry promotes efficient chip evacuation, while the bright uncoated finish suits applications where coating buildup is a concern. It is sized and toleranced to the h8 standard per DIN specification. Licensed HVAC, mechanical, and industrial trades routinely use carbide jobber bits for drilling through aluminum and similar non-ferrous materials where tool life and hole quality matter.

This bit is built for general-purpose drilling in aluminum and other primary workpiece materials coded N under the DIN material classification system. With an overall length of 86 millimeters (approximately 3.39 inches) and a flute length of 52 millimeters (approximately 2.05 inches), it fits standard jobber-length drill chucks. The straight-cylindrical shank with a diameter of 4.85 millimeters (approximately 0.191 inches) seats securely in three-jaw chucks and collet-style tool holders commonly used in CNC and manual drilling setups. Series 732 designates this as part of a consistent Guhring carbide jobber product family suited for shop and field use.

Key Features

• Solid carbide construction for extended tool life in non-ferrous and general-purpose drilling
• 118-degree faceted point with web thinning for accurate centering and reduced thrust force
• Spiral flute geometry with 5xD flute-to-diameter ratio promotes reliable chip removal
• Bright uncoated finish — no added coating buildup, compatible with cutting fluids or dry drilling
• DIN h8 diameter tolerance for consistent, repeatable hole sizing
• Right-hand cut, straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as an OEM-style general-purpose carbide jobber drill bit suitable for use in manual drill presses, CNC machining centers, and hand-held drilling equipment accepting a straight-cylindrical shank of approximately 0.191 inches in diameter.

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists or trade professionals familiar with cutting tool safety. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits, as carbide is brittle and susceptible to breakage under lateral loading. Always power down and de-energize the spindle before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when drilling non-ferrous materials.
