Guhring 9010180091000 Cobalt Jobber Drill 9.10mm

Product Description

The GUHRING 9010180091000 is a cobalt steel jobber-length drill bit designed for heavy-duty drilling in ferrous and non-ferrous metals. It features a 135-degree split point that reduces walking on entry and lowers thrust requirements, making it well suited for production and maintenance drilling. The bronze oxide coating provides mild lubricity and heat resistance during cuts. With a parabolic flute geometry, chips evacuate efficiently even in deeper holes, reducing the need for peck drilling in many applications. This is a right-hand cutting, two-flute design built to DIN and NAS specification standards and classified as a heavy-duty grade bit.

This drill bit is intended for cutting steel, cast iron, aluminum, and other non-ferrous materials. It is commonly used in metal fabrication shops, maintenance and repair operations, and general machining environments where a reliable, mid-size jobber drill is needed. The straight cylindrical shank fits standard three-jaw drill chucks found on drill presses, CNC machining centers, and hand-held power drills. The 5xD flute-to-diameter ratio and h8 shank diameter tolerance make it appropriate for applications that demand consistent hole sizing and repeatability.

Key Features

• Cobalt steel construction with bronze oxide coating for heat and wear resistance
• 135-degree split point reduces thrust and minimizes bit walking on entry
• Parabolic flute geometry promotes fast chip evacuation in steel and cast iron
• Right-hand cutting, two-flute design with web-thinned point
• Straight cylindrical shank with h8 tolerance for consistent chuck fit
• Meets DIN and NAS specification designations; heavy-duty grade classification

Compatibility

Designed for use in standard three-jaw chucks accepting a 9.1 mm straight shank. Suitable for drilling steel, cast iron, aluminum, and non-ferrous workpiece materials as indicated by the manufacturer.

Installation Notes

Installation is performed by machinists, toolroom technicians, and maintenance trades using a drill press, hand drill, or CNC spindle with an appropriate chuck or collet. Ensure the shank is fully seated and the chuck is tightened before operation. Use cutting fluid or coolant appropriate for the workpiece material to extend tool life, particularly when drilling steel. Inspect the cutting edges and point for wear or chipping before each use and replace the bit if edge integrity is compromised.
