Guhring 9055180075000 Carbide Jobber Drill 7.50mm

Product Description

The GUHRING 9055180075000 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding production environments. It features a 7.50 mm (0.2953 inch) diameter, a 130-degree point angle with a proprietary point geometry, and a three-flute regular spiral flute design. The web-thinned construction reduces thrust and improves chip evacuation. With an overall length of 91.00 mm (3.5827 inches) and a flute length of 53.00 mm (2.0866 inches), this drill is built to DIN specification standards. It operates in a right-hand cutting direction without coolant-through capability. The shank diameter measures 8 mm. This bit is intended for installation by machinists and tool-room professionals in CNC, manual, and production drilling operations.

This drill is rated for use in cast iron, aluminum, and non-ferrous materials, making it suitable for both production shops and job-shop environments where material types vary. The 5xD flute-to-diameter ratio supports controlled chip flow in deeper holes. The bright/uncoated finish makes it well suited for non-ferrous applications where coated tools may cause material adhesion. The 130-degree point angle delivers aggressive cutting action with minimal walking on entry, reducing the need for a center-drill operation in many applications. Licensed machinists and CNC operators handling close-tolerance work in light metals and cast iron will find this drill consistent with standard carbide tooling protocols.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 130-degree proprietary point angle reduces thrust and improves entry accuracy
• Three-flute design improves chip evacuation compared to standard two-flute geometry
• Web-thinned point lowers cutting force at the drill tip
• Right-hand cut, regular spiral flute, compatible with standard CNC and manual spindle rotation
• Bright/uncoated finish optimized for aluminum and non-ferrous workpieces

Compatibility

Rated for primary use in cast iron, aluminum, and non-ferrous workpiece materials. Fits any spindle or chuck accepting an 8 mm shank. Conforms to DIN specification for jobber-length carbide drills in the 7.00 mm to 8.00 mm size range.

Installation Notes

This drill should be installed by qualified machinists following standard toolholding procedures for solid carbide tooling. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Solid carbide drills are brittle and should not be used in setups with excessive runout or unsupported workpiece conditions, as lateral loading can cause fracture. Follow machine manufacturer guidelines and applicable shop safety standards when programming feeds and speeds for carbide tooling.
