Accupro 12183724 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO 12183724 is a solid micrograin carbide corner radius end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 1/2 inch mill diameter, a 0.06 inch corner radius, and 4 right-hand spiral flutes with a 40-degree helix angle. The extra-long configuration provides a 6 inch overall length and a 1-1/2 inch length of cut, making it well suited for reaching into deep pockets or profiling tall workpiece features. The bright/uncoated finish makes it compatible with a wide range of cutting fluids and base materials. This single-end, centercutting tool can plunge directly into material without a pre-drilled entry point.

This end mill is intended for use in CNC machining centers, vertical mills, and manual mills where corner radius profiling and pocket milling are required. The extra-long reach is particularly useful for aerospace, mold-and-die, and general precision machining applications where standard-length tools cannot reach the required depth. It accepts a 1/2 inch shank, fitting ER collet chucks, end mill holders, and other standard 1/2 inch bore toolholders commonly found in production shops.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• 0.06 inch corner radius reduces stress concentrations and extends workpiece life
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge entry without a pilot hole
• Extra-long 6 inch OAL with 1-1/2 inch length of cut for deep-reach applications
• Bright/uncoated finish suitable for use with most cutting fluids and materials

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any CNC or manual milling machine equipped with a 1/2 inch shank toolholder, including ER collet systems and end mill holders with a 1/2 inch bore.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per standard shop safety procedures. Ensure the shank is fully seated and properly torqued in the toolholder before operation. Verify runout with a dial indicator after installation, particularly given the extra-long reach, as deflection and runout are amplified at greater gage lengths. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material.
