Kennametal 7102461 Corner Radius End Mill 0.75in 8 Flute

Product Description

The KENNAMETAL 7102461 is a solid carbide corner radius end mill engineered for demanding milling applications in ferrous and high-temperature alloy materials. Part of the HARVI IV series, it features an 0.75-inch diameter with eight flutes and a variable helix geometry at 35 degrees to reduce chatter and improve surface finish at aggressive feed rates. The AlCrN coating provides thermal stability and wear resistance in dry or minimal-lubrication cutting conditions. Coolant-through capability supports chip evacuation during deep-cavity and slotting operations. This tool is installed by machinists and CNC tooling specialists in production and job-shop environments.

The 7102461 is suited for high-efficiency milling in vertical and horizontal machining centers. Its 1.625-inch length of cut and 4-inch overall length make it appropriate for medium-depth pocketing and profiling operations. The noncentercutting design means this end mill is intended for ramping or helical interpolation entry rather than direct plunge cuts. The 0.060-inch corner radius reduces stress concentration at the cutting edge, extending tool life in abrasive workpiece materials. Right-hand flute direction and right-hand cutting configuration are standard for conventional spindle setups.

Key Features

• 8-flute solid carbide construction for high metal-removal rates and rigidity
• Variable helix geometry reduces harmonic vibration during aggressive cuts
• AlCrN coating delivers high-temperature hardness and oxidation resistance
• Coolant-through design promotes chip evacuation in deep-cavity milling
• 0.060-inch corner radius protects cutting edge and reduces workpiece stress risers
• Noncentercutting geometry requires ramp or helical entry - not direct plunge

Compatibility

Designed as a direct-fit toolholder replacement for standard 0.75-inch straight-cylindrical shank collet chucks and hydraulic or shrink-fit holders used in CNC machining centers. Also referenced under manufacturer catalog number HA4R8RA0750R163HAR060I.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Secure the straight-cylindrical shank in a properly sized collet, hydraulic, or shrink-fit holder to the manufacturer-specified gauge length before spindle engagement. Confirm spindle RPM, feed rate, and axial depth of cut against the HARVI IV series application guidelines before running the program. Because this tool is noncentercutting, program a ramp or helical interpolation entry to avoid tool damage on the initial cut engagement.
