Accupro 12182124 Corner Radius End Mill 3/4 in 3 Flute

Product Description

The ACCUPRO 12182124 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 3/4 inch diameter, a 1-1/2 inch length of cut, and a 0.015 inch corner radius that produces a controlled, repeatable edge break on finished workpiece surfaces. Built from micrograin solid carbide, this tool delivers the rigidity and wear resistance required for ferrous and non-ferrous cutting applications. It is a single-end, centercutting tool with a right-hand flute direction and right-hand cutting action, making it compatible with standard CNC and manual milling setups. Professional machinists and tool-and-die shops rely on this end mill for slot milling, profiling, and finishing cuts where edge integrity matters.

This end mill is suited for use in production machining, job shops, and toolroom environments where tight tolerances and consistent corner geometry are required. The bright, uncoated finish makes it a versatile choice across a range of workpiece materials, including aluminum, steel, and other common metals. The 3/4 inch shank diameter seats securely in standard collets and end mill holders. With a 40-degree helix angle and spiral flute geometry, this tool promotes efficient chip evacuation during both roughing and finishing passes.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 0.015 inch corner radius for consistent, repeatable edge geometry on finished surfaces
• 3 flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows for plunge entry into the workpiece
• Right-hand cut and right-hand flute direction for use in standard spindle setups
• Bright, uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as a direct-fit replacement for standard 3/4 inch shank end mill holders, collet chucks, and milling machine spindles accepting 3/4 inch tooling. Confirm holder runout tolerance and drawbar torque specifications against your machine tool requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Power down and lock out the machine spindle before inserting or removing the tool. Seat the shank fully into the collet or holder to the manufacturer-specified minimum engagement depth, and torque the clamping system per your toolholder specifications. Inspect the cutting edges for chips or damage before each use, and do not exceed the recommended speeds and feeds for the workpiece material.
