Guhring 9038910095000 Corner Chamfer End Mill 9.5mm 3 Flute

Product Description

The GUHRING 9038910095000 is a solid carbide corner chamfer end mill designed for high-performance metal removal in demanding machining environments. Built on the Series 3891 platform, it features a 9.5 mm cutting diameter, a 22 mm length of cut, and three helical flutes with a variable helix geometry that reduces chatter and improves surface finish. The 0.14 mm chamfer width at a 45-degree angle protects the cutting corner and extends tool life on edge-breaking and shouldering operations. FIREX PVD coating - a TiAlN and TiN multilayer finish - provides thermal resistance and wear protection at elevated cutting temperatures. This tool is centercutting and extended reach, making it suitable for plunging, ramping, and helical interpolation strategies. Machinists and CNC operators in job shops, aerospace, and precision manufacturing environments are the primary users.

This end mill is optimized for primary workpiece materials including steel, stainless steel, superalloys, and titanium (ISO material codes P, M, S). It also performs in secondary applications on cast iron and non-ferrous metals (codes K, N). The coarse pitch and variable helix design suit roughing and slotting operations where chip evacuation and vibration control are priorities. The extended reach neck diameter of 9.2 mm and 30 mm reach length allow access to deeper pockets and stepped features without sacrificing rigidity. Typical applications include shouldering, slotting, ramp-down entry, helical interpolation, drill-mill operations, and plunging and recessing cycles.

Key Features

• Variable helix, helical flute geometry reduces vibration during roughing and interrupted cuts
• FIREX PVD coating (TiAlN plus TiN) delivers thermal and abrasion resistance for hard and exotic alloys
• Centercutting design enables plunging, ramp-down, and helical interpolation without a pre-drilled pilot
• 45-degree corner chamfer at 0.14 mm width protects cutting corners and produces consistent edge breaks
• Extended reach with 9.2 mm neck diameter and 30 mm reach length accesses deep pockets
• Single-end, straight-cylindrical shank with h6 tolerance for precise collet or end mill holder fitment

Compatibility

Designed for use in standard straight-bore end mill holders, collet chucks, and hydraulic holders accepting a 10 mm shank diameter. Suitable for CNC machining centers running steel, stainless steel, superalloys, titanium, cast iron, and non-ferrous metal workpieces.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Secure the 10 mm shank in a balanced end mill holder or precision collet chuck to the manufacturer-recommended gauge length before use. Ensure the machine spindle and tool holder are clean and free of debris before clamping. Follow applicable shop safety procedures and machine tool operating standards when setting tool offsets and running initial cuts.
