Kennametal 7102892 Corner Radius End Mill 3/4 in 8 Flute

Product Description

The KENNAMETAL 7102892 is a solid carbide corner radius end mill from the HARVI IV series, designed for high-performance milling in demanding machining environments. The tool features a 3/4 inch (19.05 mm) diameter with an 8-flute configuration and a 1.52 mm corner radius, delivering fine edge detail while extending tool life under aggressive cutting conditions. An AlCrN coating provides thermal resistance and wear protection at elevated cutting temperatures. The variable helix geometry reduces harmonic chatter, and through-coolant capability supports chip evacuation and heat management during deep cuts. This tool is intended for use by CNC machinists and tooling professionals in precision metal-removal applications.

The KENNAMETAL 7102892 is suited for finishing and semi-finishing passes in ferrous and difficult-to-machine alloys. With a 1-5/8 inch length of cut (41.28 mm) and a 4 inch overall length, it fits standard CNC machining centers and milling machines using 3/4 inch straight-cylindrical shank toolholders. The chipbreaker geometry and right-hand cutting direction support high-feed strategies. This tool is a single-end design, meaning it is not reversible, and is catalogued under Kennametal series HARVI IV with manufacturer catalog number HA4R8RA0750R163HAR060D.

Key Features

• 8-flute solid carbide construction for high material removal rates and rigidity
• AlCrN coating for superior heat and wear resistance in alloy steels and hardened materials
• Variable helix design reduces chatter and improves surface finish
• Through-coolant capability supports chip evacuation and thermal management
• 1.52 mm corner radius protects cutting edges and reduces stress concentrations at corners
• Chipbreaker geometry integrated for improved chip control in deep-pocket applications

Compatibility

Designed for use in CNC machining centers accepting a 3/4 inch straight-cylindrical shank. Part of the KENNAMETAL HARVI IV series; refer to Kennametal catalog number HA4R8RA0750R163HAR060D for cross-reference and system compatibility confirmation.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Secure the shank in a clean, properly sized collet or milling chuck to the toolholder manufacturer's specified clamping torque range. Verify runout with a dial indicator before commencing cuts, and confirm coolant passages are clear when using through-coolant.
