Guhring 9069850095220 Corner Radius End Mill 3/8 in

Product Description

The GUHRING 9069850095220 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. With a 3/8-inch mill diameter, a 0.02-inch corner radius, and 5 helical flutes, this single-end tool is built for both roughing and finishing operations. The nano-A coating improves wear resistance and surface finish quality across a broad range of workpiece materials. It is suited for use in CNC machining centers with standard end mill holders and is specified under GUHRING Series 6985.

This end mill is intended for ferrous and non-ferrous applications including steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. The short flute length and medium-high helix angle make it well-suited for stable cutting in tight-tolerance environments. It is commonly used in shops running precision mold work, die work, and general production machining where corner integrity and surface finish are critical.

Key Features

• Solid carbide construction for rigidity and heat resistance at high feed rates
• nano-A coating for extended tool life across steel, stainless, cast iron, and titanium
• 0.02-inch corner radius with a tolerance of -0.002 to 0.002 inches for repeatable edge geometry
• 5 helical flutes with right-hand cutting and right-hand flute direction for efficient chip evacuation
• Single-end, straight-cylindrical shank compatible with standard end mill holders
• Rated for both roughing and finishing material removal in one tool

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 as designated by material codes P, M, K, S, N, and H.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before installing or removing the tool. Seat the shank fully into a clean, undamaged end mill holder and torque the set screw or collet to the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will degrade corner radius accuracy and reduce tool life.
