Guhring 9030910127070 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The GUHRING 9030910127070 is a solid carbide corner radius end mill designed for precision finishing operations in ferrous and hard materials. It features a 1/2 inch cutting diameter, a 0.09 inch corner radius, and six helical flutes with a close pitch configuration for smooth chip evacuation and a fine surface finish. The FIREX coating provides thermal resistance and wear protection, extending tool life in demanding applications. This is a single-end, right-hand cutting, right-hand flute tool built for use in end mill holders on CNC machining centers and manual mills. Licensed machinists and tool and die technicians are the primary users.

This end mill is suited for finishing passes on steel, stainless steel, cast iron, superalloys, and titanium as primary workpiece materials. Secondary applications include non-ferrous metals and hard materials. The 1 inch length of cut and 3 inch overall length make it appropriate for standard-depth peripheral and slot finishing in Series 3091 applications. The corner radius geometry reduces stress concentration at the cutting edge and improves part surface quality on profiled or contoured workpieces in both job shop and production environments.

Key Features

• Solid carbide substrate for rigidity and wear resistance in hard and abrasive materials
• FIREX coating for elevated thermal and oxidation resistance during high-speed cuts
• 0.09 inch corner radius with tolerance of -0.02 to 0.02 inches for controlled edge geometry
• 6-flute close-pitch design optimized for finishing with reduced chip load per tooth
• Right-hand cut and right-hand helix for standard spindle compatibility
• Straight cylindrical shank for direct use in standard end mill holders

Compatibility

Designed for use with end mill holders. Compatible with workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. Mill diameter tolerance is h10; shank diameter tolerance is h6.

Installation Notes

Installation is performed by machinists or CNC setup technicians. The tool shank must be fully seated and properly torqued in a clean, undamaged end mill holder before operation. Inspect the holder bore and collet for runout before securing the tool, as excessive runout accelerates edge wear on carbide tooling. Confirm spindle direction is set to right-hand rotation before initiating a cut.
