Guhring 9055190035700 Cobalt Jobber Drill Bit 9/64 in

Product Description

The GUHRING 9055190035700 is a cobalt jobber-length drill bit with a titanium nitride (TiN) coating, designed for precision drilling in metalworking and fabrication applications. Built to DIN 338 standards, it carries an M35 cobalt material grade that provides elevated heat resistance and edge retention compared to standard high-speed steel. The 118-degree four-facet split point reduces walking and thrust on entry, while the web-thinned, tapered web geometry improves chip evacuation. Overall length is 70 millimeters with a 39-millimeter flute length and a straight-cylindrical shank measuring 9/64 inch (0.1406 inch) in diameter. Installed by machinists, tool-and-die professionals, and general metalworkers.

This bit is suited for drilling aluminum, steel, stainless, and a range of ferrous and non-ferrous workpiece materials, aligning with material codes K, M, N, and P. The 5xD flute-to-diameter ratio and regular spiral flute profile support controlled chip flow in both hand-held and machine-mounted drilling setups. Maximum drilling depth reaches 1.325 inches (33.65 millimeters). It is sold individually and fits standard drill chucks accepting a 9/64-inch straight shank.

Key Features

• M35 cobalt construction for improved heat and wear resistance over standard HSS
• TiN coating reduces friction and extends cutting edge life
• 118-degree four-facet split point minimizes walking and reduces required thrust
• Web-thinned tapered web improves chip evacuation during through-hole drilling
• DIN 338 standard geometry ensures dimensional consistency and toolholder compatibility
• Right-hand cut, regular spiral flute, no coolant-through requirement

Compatibility

Designed as an OEM-specification replacement or standard-stock jobber drill for use in any drill press, CNC machine, or hand drill accepting a 9/64-inch straight-cylindrical shank. Compatible workpiece materials include aluminum, mild steel, stainless steel, and cast iron per material codes K, M, N, and P as specified in the product data.

Installation Notes

Install and remove drill bits only after the spindle has come to a complete stop and the machine is de-energized or the drill is unplugged. Secure the straight shank fully within the chuck jaws and tighten with a chuck key before starting the spindle. Use appropriate cutting fluid or lubricant for the workpiece material to maximize bit life, particularly when drilling stainless or hardened steel. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.
