Guhring 9030910095240 Corner Radius End Mill 3/8in 6 Flute

Product Description

The GUHRING 9030910095240 is a solid carbide corner radius end mill designed for finishing operations in ferrous and difficult-to-machine materials. It features a 3/8 inch mill diameter, a 0.031 inch corner radius, and 6 helical flutes with a high helix angle of 45 degrees. The cutting geometry is right-hand with a close pitch flute pattern, and the tool carries a FIREX coating for extended tool life in demanding applications. Overall length is 2.5 inches with a 1 inch length of cut. It is a single-end, straight-shank tool intended for use in end mill holders on CNC machining centers and manual mills.

This end mill is suited for finishing passes in steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. The Series 3091 geometry is optimized for close-tolerance profile and contour work where corner integrity is critical. Typical applications include die and mold finishing, aerospace component profiling, and precision part machining in job shop or production environments. It is installed in standard end mill holders with a 3/8 inch bore.

Key Features

• FIREX coating provides heat and wear resistance in ferrous and hard-material cutting
• 6-flute, high helix design supports fine surface finish and efficient chip evacuation
• 0.031 inch corner radius reduces stress concentration and extends workpiece edge life
• Solid carbide construction delivers rigidity for finishing and tight-tolerance profiling
• Right-hand cut and flute direction for use in standard CNC and manual spindles
• Straight-cylindrical shank with h6 tolerance fits end mill holders with minimal runout

Compatibility

Designed for use with end mill holders accepting a 3/8 inch straight-cylindrical shank. Compatible with primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium, as well as secondary materials including non-ferrous metals and hard materials.

Installation Notes

Installation is performed by a machinist or tooling technician using a properly sized end mill holder torqued per holder manufacturer specifications. Confirm spindle is fully stopped and machine is in a safe state before tool changes. Do not exceed the recommended depth of cut or feed rate for the workpiece material and machine rigidity. Runout should be checked after installation to protect corner radius integrity on finishing passes.
