Guhring 9067590095270 Corner Radius End Mill 3/8 in

Product Description

The GUHRING 9067590095270 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. Built on the RF100 Series 6759 platform, it features a 3/8 inch mill diameter, 0.09 inch corner radius, and a 4-flute variable helix geometry that reduces harmonic chatter during both roughing and finishing passes. The nano-Si coating provides enhanced heat resistance and surface hardness, extending tool life in abrasive and high-temperature cutting conditions. A straight-cylindrical shank and right-hand helical flutes make this tool a reliable choice for machinists working with ferrous and non-ferrous alloys on CNC mills and machining centers.

This end mill is suited for single-end milling operations on steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. The variable index design helps distribute cutting forces evenly, making it effective for both roughing and finishing in a single setup. It seats in standard end mill holders and is appropriate for vertical and horizontal machining centers in job shop, tool room, and production environments. The corner radius geometry reduces stress concentration at the cutting edge, improving tool life when machining tough alloys.

Key Features

• 3/8 inch mill diameter with 0.09 inch corner radius for edge strength and blending
• Variable helix and variable index geometry reduce vibration during cutting
• nano-Si coating improves wear resistance on steel, stainless, cast iron, superalloys, and titanium
• 4 helical flutes support both roughing and finishing material removal
• Straight-cylindrical shank fits standard end mill holders
• Right-hand cut, right-hand flute direction with standard pitch

Compatibility

Designed for use with standard end mill holders. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. Compatible with CNC vertical and horizontal machining centers accepting 3/8 inch straight shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or drawbar is disengaged before mounting or removing the tool. Seat the shank fully into the end mill holder and torque the retention mechanism to the holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, particularly given the tight corner radius tolerance of -0.002 to 0.002 inches.
