Accupro 12182941 Corner Radius End Mill 1/2 in 4 Flute Ticn

Product Description

The ACCUPRO 12182941 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 0.5 inch mill diameter, a 5/8 inch length of cut, and a 0.020 inch corner radius that reduces stress concentrations and extends tool life at the cutting edge. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating improves surface hardness and wear resistance, making it well suited for ferrous and non-ferrous materials. This end mill is used by machinists and toolroom professionals on CNC machining centers and manual mills.

This tool is appropriate for stub-length milling applications where a short, rigid setup is required. The single-end, centercutting design allows for plunge cutting as well as peripheral and slot milling. With right-hand flute direction and right-hand cutting, it is compatible with standard spindle configurations. The 1/2 inch shank diameter fits common collet and end mill holder systems. Typical applications include profiling, contouring, and finish milling of pockets and slots in production and repair machining environments.

Key Features

• 0.020 inch corner radius reduces edge chipping and stress at the tool tip
• TiCN coating provides enhanced wear resistance and surface hardness
• 40-degree helix angle promotes efficient chip flow and reduced cutting forces
• Centercutting design enables direct plunge entry into workpiece material
• Micrograin solid carbide construction for rigidity and dimensional stability
• Right-hand cut and right-hand spiral for standard CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for 1/2 inch collet chucks, end mill holders, and compatible toolholding systems used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Secure the shank to the recommended engagement depth in the toolholder and verify runout with a dial indicator before cutting. Consult machine and toolholder manufacturer specifications for proper torque values on set screws or collet nuts.
