Guhring 9038760254090 Corner Radius End Mill

Product Description

The GUHRING 9038760254090 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. It features a 1 inch cutting diameter, a 1-1/2 inch length of cut, and a 1/8 inch (0.1250 inch) corner radius that reduces stress concentration at part edges. The variable helix and variable index geometry help break up harmonic chatter, improving surface finish and tool life. With a Super-A coating and 4 helical flutes, this end mill handles both roughing and finishing passes in a single tool. It is intended for use by professional machinists in CNC milling applications requiring precision and durability.

This end mill is suited for milling steel, cast iron, superalloys, titanium, stainless steel, and hard materials. The 4 inch overall length and 1 inch Weldon flat shank make it compatible with standard end mill holders used in vertical and horizontal machining centers. It is a right-hand cut, right-hand flute, single-end tool with a centercutting designation indicated as No in the spec attributes, meaning plunge milling is not recommended. Typical applications include shoulder milling, profiling, and contour milling on production or job-shop floors.

Key Features

• 1 inch cutting diameter with 1/8 inch corner radius for edge strength and part geometry control
• Variable helix and variable index geometry reduces vibration and chatter during cut
• Super-A coating extends tool life on steel, cast iron, superalloys, titanium, and hard materials
• 4 helical flutes support both roughing and finishing material removal
• Weldon flat shank provides positive drive engagement in end mill holders
• Series 3876 solid carbide construction for rigidity in high-speed and high-load applications

Compatibility

Designed for use with standard end mill holders. Primary workpiece materials include steel, cast iron, superalloys, and titanium (material codes P, K, S). Secondary workpiece materials include stainless steel and hard material (material codes M, H). Part of the GUHRING Series 3876 product line.

Installation Notes

This tool is installed by a qualified machinist or toolroom technician. Secure the Weldon flat shank firmly in a compatible end mill holder and verify runout before operation. Power down and lock out the machine spindle before changing tooling per standard machine shop safety practice. Do not use this end mill for plunge cutting, as it is not a centercutting geometry.
