Accupro 12182350 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 12182350 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining applications. It features a 1 inch mill diameter, a 1-3/4 inch length of cut (0.8750 inches decimal), and a 0.02 inch corner radius that reduces stress concentration at cutting edges and extends tool life compared to sharp-corner geometry. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finish. The bright/uncoated finish is suited for use in a range of common workpiece materials. This tool is installed and operated by machinists and CNC programmers working in job shop or production environments.

This end mill is appropriate for side milling, slotting, and profiling operations on ferrous and non-ferrous metals where a controlled corner radius is required. The centercutting capability allows plunge entry into the workpiece. With a 1 inch shank diameter and 4 inch overall length, it is compatible with standard end mill holders and collet chucks used in vertical machining centers and manual knee mills. The single-end configuration and right-hand cutting direction are standard for conventional CNC milling setups.

Key Features

• 1 inch mill diameter with tight tolerance of +0.000000 to -0.002500 inches
• 0.02 inch corner radius reduces edge chipping and stress at corners
• 4-flute right-hand spiral with 40-degree helix for efficient chip evacuation
• Micrograin solid carbide construction for rigidity and wear resistance
• Centercutting design allows direct plunge entry
• Bright/uncoated finish for general-purpose milling applications

Compatibility

Designed as a direct-fit replacement for standard 1 inch shank end mill holders, collet chucks, and shrink-fit tooling used in CNC vertical machining centers and manual milling machines requiring a corner radius end mill geometry.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank to the full recommended engagement depth in the holder and torque retention screws or collet nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
