Accupro 12181541 Corner Radius End Mill 3/4in 2 Flute Ticn

Product Description

The ACCUPRO 12181541 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 3/4 inch cutting diameter, a 1/8 inch corner radius, and a TiCN (Titanium Carbonitride) coating that improves wear resistance and extends tool life in abrasive cutting conditions. The 2-flute, right-hand spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 4 inches overall length with a 1-1/2 inch length of cut, this end mill fits standard milling setups used by machinists and tooling professionals in job shop and production environments.

This end mill is suited for profile milling, slotting, and contouring applications where a blended corner radius is required to reduce stress concentration in machined parts. The centercutting design allows plunge entry into the workpiece. The micrograin carbide substrate provides consistent edge integrity across a range of materials including alloy steels, stainless, and hardened workpieces. It is a single-end tool intended for use in CNC machining centers and manual knee mills with appropriate collet or end mill holders.

Key Features

• 3/4 inch mill diameter with 1/8 inch corner radius for blended edge profiles
• TiCN coating for increased surface hardness and abrasion resistance
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge entry
• Micrograin solid carbide substrate for edge stability and long tool life
• Right-hand flute direction and right-hand cutting for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/4 inch end mill holders, collet chucks, and shrink-fit holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the recommended engagement depth in the holder and torque the set screw or collet nut according to the holder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
