Guhring 9068750095200 Corner Chamfer End Mill 3/8 in 4 Flute

Product Description

The GUHRING 9068750095200 is a solid carbide corner chamfer end mill designed for precision metal removal in demanding machining applications. Built on the Series 6875 platform, this single-end mill features a 3/8-inch cutting diameter, 4 helical flutes, and a 45-degree chamfer angle with a 0.0040-inch chamfer width. The TiAlSiN PVD nano-Si coating provides thermal resistance and wear protection for extended tool life. The variable helix geometry reduces chatter and improves surface finish across a wide range of cuts. Centercutting capability and coolant-through design make this tool suitable for high-efficiency operations. Machinists and tool-and-die professionals select this end mill for its versatility across multiple cut types and workpiece materials.

This end mill is rated for use on steel, stainless steel, cast iron, superalloys, and titanium as primary workpiece materials, with non-ferrous metals as a secondary application. The tool supports shouldering, slotting, ramp-down, helical interpolation, drill mill operations, and plunging and recessing. The combination of roughing and finishing material removal capability makes it suitable for production environments where multiple operations are performed in a single setup. The straight-cylindrical shank and standard 3/8-inch shank diameter allow direct mounting in collet chucks and end mill holders without adapters.

Key Features

• TiAlSiN PVD nano-Si coating for high-temperature wear resistance on ferrous and exotic alloys
• Variable helix flute geometry reduces harmonic vibration and chatter during cutting
• Centercutting design enables plunging and ramp-down entry without pre-drilling
• Coolant-through construction delivers cutting fluid directly to the cutting zone
• 45-degree chamfer angle at 0.0040-inch width for consistent edge preparation and deburring
• Micrograin carbide substrate supports high-speed feeds and extended tool life on hard materials

Compatibility

Designed as an OEM-style solid carbide corner chamfer end mill for use in standard 3/8-inch collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state per applicable shop safety procedures. Ensure the collet or toolholder bore is clean and free of chips before seating the shank. Verify runout after clamping, as excessive runout accelerates wear on fine-geometry end mills. Consult the machine tool manufacturer and applicable OSHA or ANSI standards for cutting speed and feed guidelines specific to the workpiece material and spindle type.
