Accupro 12182462 Corner Radius End Mill 1/4 in 4 Flute Carbide

Product Description

The ACCUPRO 12182462 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1/4 inch cutting diameter with a 0.02 inch corner radius, a 3/4 inch length of cut, and a 40-degree helix angle. The TiCN coating improves surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. With four flutes and a right-hand cutting and flute direction, it delivers efficient chip evacuation and a smooth finish. The centercutting design allows for plunge milling in addition to standard peripheral cuts. This tool is sold individually and suits professional machinists and toolroom technicians who require tight-tolerance work.

This end mill is suited for use on CNC machining centers, knee mills, and manual or automated milling machines. The 1/4 inch shank diameter fits standard ER collets and end mill holders commonly found in both production and job-shop environments. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades, making it appropriate for finishing passes and light-to-moderate roughing in steel, stainless steel, cast iron, and harder alloys. The single-end configuration and 2-1/2 inch overall length make it a practical choice for tight-clearance setups and general-purpose profiling, slotting, and contouring work.

Key Features

• TiCN coating increases surface hardness and reduces wear in demanding materials
• Micrograin solid carbide substrate supports higher speeds and feeds with improved rigidity
• 0.02 inch corner radius reduces stress concentrations and improves edge strength at part corners
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting design enables plunge entry without a pre-drilled start hole
• Right-hand flute and cutting direction compatible with standard spindle rotation on most milling machines

Compatibility

Designed as an OEM-style replacement and standard tooling option for 1/4 inch shank end mill holders and ER collet chucks used in CNC and manual milling applications.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully within the collet or end mill holder to the recommended grip length before tightening. Power down and lock out the spindle before changing tooling. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
