Guhring 9030910158740 Corner Radius End Mill 5/8 in 6 Flute

Product Description

The GUHRING 9030910158740 is a solid carbide corner radius end mill designed for high-performance finishing operations in ferrous and non-ferrous materials. It features a 5/8-inch cutting diameter, a 1-1/4-inch length of cut, and a 0.031-inch corner radius that reduces stress concentrations and extends tool life at part transitions. The 6-flute, right-hand helical geometry with a close pitch and high helix angle promotes smooth chip evacuation and superior surface finish. A FIREX coating provides thermal and oxidation resistance, making this tool well-suited for demanding cutting environments. Machinists and tool-and-die professionals use this end mill in CNC machining centers with standard end mill holders.

This end mill is built for finishing passes in steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. Its single-end, straight-cylindrical shank design fits directly into standard end mill holders. The 3-1/2-inch overall length provides adequate reach for most milling setups without sacrificing rigidity. It is not centercutting, so it is intended for side milling, profiling, and contour finishing rather than direct plunge operations. The Series 3091 designation places it within a consistent GUHRING tooling family for repeat ordering and system compatibility.

Key Features

• 0.031-inch corner radius reduces tool stress and improves part surface quality at edges
• FIREX coating provides high thermal resistance for extended tool life in tough alloys
• 6-flute close-pitch geometry optimized for finishing cuts with fine surface finishes
• High helix angle promotes efficient chip flow in deep-pocket and contour applications
• Right-hand cut, right-hand flute direction for standard CNC spindle compatibility
• Solid carbide construction delivers rigidity and wear resistance across a broad material range

Compatibility

Compatible with standard end mill holders. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. Not centercutting; designed for side milling and finishing operations rather than plunge cutting.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the holder. Secure the straight-cylindrical shank to the specified clamping torque of the end mill holder manufacturer. Verify runout with a dial indicator before beginning cuts, as excessive runout on a 6-flute finisher will rapidly degrade surface quality and tool life.
