Guhring 9006580028200 Cobalt Drill Bit No. 34 Tin

Product Description

The GUHRING 9006580028200 is a cobalt jobber length drill bit sized at No. 34 wire gauge (0.1110 inches decimal), designed for high-performance drilling in demanding metalworking applications. It carries a titanium nitride (TiN) coating that improves surface hardness and wear resistance, extending tool life in production environments. The 130-degree split point promotes accurate self-centering and reduces thrust. A parabolic flute geometry improves chip evacuation, making it suitable for deeper holes and interrupted cuts. The overall length is 2-13/32 inches with a flute length of 1-5/16 inches. This bit is installed and used by machinists, toolroom technicians, and maintenance trades working on precision drilling operations.

This drill bit is engineered for cutting cast iron and steel, covering primary workpiece material codes K and P. It is well-suited for general-purpose production drilling, MRO maintenance drilling, and light manufacturing where tight diameter tolerances are required. The straight-cylindrical shank fits standard drill chucks without special collets. The 5xD flute-to-diameter ratio and web-thinned tapered web design allow this bit to reach a maximum drilling depth of 1.133 inches. It is sold individually and is appropriate for bench drills, drill presses, and CNC machining centers.

Key Features

• Cobalt substrate with TiN coating for extended wear life in ferrous materials
• 130-degree standard point angle with web-thinned tapered web for reduced thrust and accurate entry
• Parabolic flute profile at 5xD ratio promotes efficient chip clearance in deeper cuts
• Right-hand cut, straight-cylindrical shank — compatible with standard drill chucks
• Conforms to DIN 338 specification for jobber length drills

Compatibility

Designed as a DIN 338 jobber length drill bit suitable for use in standard drill chucks, drill presses, and CNC machining centers. Primary workpiece materials are cast iron (code K) and steel (code P). No specific machine model compatibility was provided by the manufacturer for this SKU.

Installation Notes

This drill bit is installed by machinists or maintenance technicians using a drill chuck sized to accept a 0.1110-inch straight-cylindrical shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck jaws are properly tightened and the bit runs true before beginning a cut. Do not exceed the recommended maximum drilling depth of 1.133 inches for this bit geometry without retracting to clear chips.
