Guhring 9038920085000 Corner Chamfer End Mill 8.5mm

Product Description

The GUHRING 9038920085000 is a solid carbide corner chamfer end mill designed for high-performance material removal in demanding machining environments. With an 8.5 mm cutting diameter, 19 mm length of cut, and a 0.10 mm chamfer at 45 degrees, this tool delivers precise edge preparation and controlled corner geometry. The variable helix flute design reduces chatter and improves chip evacuation during aggressive cuts. FIREX PVD coating - a TiAlN/TiN multilayer system - extends tool life when cutting steel, stainless steel, superalloys, and titanium. It is centercutting and suited for roughing operations. Machinists and tool-and-die professionals working on CNC milling centers are the primary users.

This end mill is built for shouldering, slotting, ramp-down entry, helical interpolation, drill-mill operations, and plunging and recessing applications. The extended reach design, with a 29 mm reach length and 8.20 mm neck diameter, provides clearance in deep-pocket and confined-cavity setups. A Weldon flat shank at 10 mm diameter with h6 tolerance ensures secure clamping in standard side-lock holders. It performs across a primary workpiece material range of steel, stainless steel, superalloys, and titanium, with secondary suitability for cast iron and non-ferrous metals. The coarse pitch geometry is optimized for roughing passes where chip load and material removal rate take priority.

Key Features

• FIREX PVD coating (TiAlN/TiN multilayer) for extended tool life in ferrous and high-temp alloy cutting
• Variable helix flute geometry reduces vibration and chatter during roughing
• Centercutting design enables plunging, ramp-down, and drill-mill entry strategies
• Extended reach with 29 mm reach length and 8.20 mm neck diameter for deep-pocket access
• Weldon flat shank provides positive retention in side-lock toolholders
• 45-degree chamfer at 0.10 mm width for consistent edge preparation

Compatibility

Designed for use in CNC milling applications involving steel, stainless steel, superalloys, titanium, cast iron, and non-ferrous metals. Part of the GUHRING Series 3892 extended-reach corner chamfer end mill family.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the Weldon flat shank in a properly sized side-lock or set-screw toolholder rated for the shank diameter before spindle operation. Verify runout with a dial indicator after clamping, as excess runout accelerates coating wear and reduces edge life on carbide tooling. Always confirm spindle speed, feed rate, and depth-of-cut parameters against the published cutting data for the workpiece material before initiating a cut.
