Guhring 9010180076000 Cobalt Jobber Drill 7.60mm

Product Description

The GUHRING 9010180076000 is a cobalt jobber-length drill bit designed for high-performance drilling in ferrous and non-ferrous materials. It carries a 7.60 mm diameter (0.2992 inch) and a 135-degree split-point geometry that reduces walking and cuts required thrust at entry. A bronze oxide coating provides lubricity and heat resistance. The overall length is 117.00 mm (4.6063 inches) with a 75.00 mm parabolic flute for improved chip evacuation at depth. This is a two-flute, right-hand cutting drill built to DIN 338 and NAS standards, appropriate for production and maintenance environments where consistent hole quality in tough materials is required.

The 9010180076000 is suited for drilling steel, cast iron, aluminum, and other non-ferrous materials in industrial and trade applications. The parabolic flute geometry makes it effective in deep-hole applications where chip packing is a common problem. The straight cylindrical shank (7.6 mm diameter) seats in standard drill chucks and collets without modification. Maximum drilling depth is 63.60 mm (2.5040 inches). The Series 1018 designation identifies it within the GUHRING heavy-duty cobalt line, built for repeated use in demanding production settings where high-speed steel bits would wear prematurely.

Key Features

• Cobalt substrate with bronze oxide coating for heat and wear resistance in ferrous and abrasive materials
• 135-degree split-point tip reduces entry thrust and eliminates center-punch requirements on most materials
• Parabolic flute geometry promotes fast, clean chip evacuation to reduce re-cutting and heat buildup
• Right-hand cutting, two-flute design compatible with standard drill chucks and collet systems
• h8 diameter tolerance on shank ensures consistent fit in precision toolholding
• Compliant with DIN 338 and NAS specification designations

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks and collets accepting a 7.6 mm straight cylindrical shank, suitable for machining steel, cast iron, aluminum, and non-ferrous workpieces per the Series 1018 heavy-duty cobalt specification.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the drill press, CNC spindle, or hand-held drill is fully powered down and locked out before changing tooling. Verify chuck or collet runout is within acceptable limits before use, as excess runout accelerates wear and degrades hole tolerance. Do not exceed the maximum drilling depth of 63.60 mm without retracting to clear chips.
