Accupro 12183166 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 12183166 is a solid carbide corner radius end mill designed for precision milling operations in metal and hard material applications. With a 1-inch mill diameter, a 3-inch length of cut, and a 0.06-inch corner radius, this tool produces smooth, radiused edges on pockets, slots, and contoured surfaces. The 4-flute, right-hand spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide with a bright, uncoated finish, it is suited for machinists and toolroom professionals working on CNC mills and manual machining centers.

This end mill is used in production and toolroom environments where an extra-long reach is required. The single-end, centercutting configuration allows plunge cutting and full-slot milling. The 6-inch overall length and 1-inch shank diameter make it appropriate for deep-cavity work and applications where standard-length tools cannot reach the workpiece. It fits collet chucks, end mill holders, and hydraulic toolholders sized for a 1-inch shank.

Key Features

• 1-inch mill diameter with 0.06-inch corner radius for radiused edge finishing
• 4 right-hand spiral flutes with 40-degree helix for efficient chip removal
• Micrograin solid carbide construction for wear resistance and rigidity
• Extra-long 6-inch overall length for deep-cavity and extended-reach applications
• Centercutting design supports plunge entry cuts
• Bright, uncoated finish suitable for a range of base materials

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual mills accepting a 1-inch straight shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked out before loading or removing the tool. Confirm the tool holder bore and collet are clean and free of chips before seating the shank. Verify runout with a dial indicator after installation and before engaging the workpiece.
