Kennametal 3876629 Corner Radius End Mill 3/4 in 2 Flute Carbide

Product Description

The KENNAMETAL 3876629 is a solid carbide corner radius end mill designed for high-performance milling of non-ferrous metals. It features a 0.75-inch mill diameter, a 1-inch length of cut, and a 4-inch overall length with a matching 0.75-inch straight cylindrical shank. The two-flute, right-hand spiral geometry with a high helix angle promotes efficient chip evacuation and smooth cutting action. The bright uncoated finish is suited for non-ferrous applications where coating buildup is a concern. The submicron carbide grade provides the toughness and edge retention needed for roughing passes in aluminum, copper, brass, and similar materials.

This end mill is intended for single-end roughing operations on non-ferrous workpieces in CNC machining environments. It carries the AADF series designation and is compatible with HC 1/2 through HC 1-1/4 hydraulic sleeves with inch bores, HC 20M through HC 32M hydraulic sleeves metric with inch bores, and HC-HSK Form A toolholders. The centercutting design allows plunge entry without a pilot hole. This tool is typically installed by machinists and CNC operators in production and job-shop settings.

Key Features

• 0.75-inch mill diameter with a matched 0.75-inch straight cylindrical shank for secure tool holding
• 1-inch length of cut suitable for short-reach roughing applications
• 2-flute right-hand spiral geometry with high helix for efficient chip evacuation in non-ferrous materials
• Centercutting capable — allows direct plunge entry without pre-drilling
• Bright uncoated finish optimized for non-ferrous metal applications where coatings may cause material adhesion
• Submicron carbide grade delivers consistent edge retention during roughing passes

Compatibility

Compatible with HC 1/2 through HC 1-1/4 hydraulic sleeves with inch bores, HC 20M through HC 32M hydraulic sleeves metric with inch bores, and HC-HSK Form A toolholders. Designed for use in non-ferrous metal milling applications per the AADF series specification.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and zero-out the spindle before changing tooling. Seat the shank fully in the toolholder and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut to avoid premature edge wear.
