Guhring 9006580063500 Cobalt Drill Bit Letter E 1/4 in

Product Description

The GUHRING 9006580063500 is a cobalt jobber-length drill bit sized at letter E (0.2500 inches decimal, 1/4 inches) with a 130-degree drill point angle and a titanium nitride (TiN) coating. Built to DIN 338 standards, it features a parabolic flute geometry and a web-thinned, tapered web construction for efficient chip evacuation and reduced thrust in demanding materials. The right-hand cut, straight-cylindrical shank fits standard drill chucks without adapters. This is a high-performance grade bit intended for machinists, fabricators, and maintenance techs drilling cast iron and steel in production or job-shop environments.

The 9006580063500 is designed for drilling cast iron and steel workpieces, covering primary workpiece material codes K and P. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 2.1060 inches (53.48 mm), it handles jobber-depth holes in both light and heavy-duty ferrous applications. The TiN coating extends tool life in abrasive ferrous materials. It is sold individually and suits CNC machines, drill presses, and hand-held power drills where a straight-shank 1/4-inch bit is required.

Key Features

• Cobalt high-performance grade construction for heat and wear resistance in ferrous materials
• TiN (titanium nitride) coating reduces friction and extends cutting edge life
• 130-degree split point with web thinning reduces walking and lowers thrust requirements
• Parabolic flute profile promotes fast chip evacuation in deep-hole drilling
• Right-hand cut, straight-cylindrical 1/4-inch shank fits standard chucks without bushing
• Manufactured to DIN 338 specification for consistent dimensional tolerances

Compatibility

Designed for drilling cast iron and steel (workpiece material codes K and P). Fits any standard drill chuck accepting a 1/4-inch (6.35 mm) straight-cylindrical shank. Conforms to DIN 338 jobber-length standards.

Installation Notes

Installation and use is performed by machinists, tool-and-die technicians, or maintenance trades operating drill presses, CNC drilling machines, or hand-held power drills. Ensure the chuck is fully tightened and the workpiece is securely clamped before drilling. Use appropriate cutting fluid or coolant for steel applications to manage heat buildup, even though this bit does not have through-coolant capability. Inspect the cutting edges for wear before each use and replace when diameter tolerance or point geometry is compromised.
