Accupro 12183615 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The ACCUPRO 12183615 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and long flute reach. Built from micrograin solid carbide, this single-end tool features a 0.045-inch corner radius and 4 right-hand spiral flutes with a 40-degree helix angle. It measures 3/4 inch in diameter with a 2-inch length of cut and a 6-inch overall length. The bright, uncoated finish is suited for applications where coating is unnecessary or undesirable. Licensed machinists and CNC operators install this tool in milling machines for high-precision material removal.

This end mill is applied in CNC machining centers and manual mills for contouring, profiling, and slotting operations where a small corner radius is required to blend surfaces and reduce stress concentrations. The long flute and extended overall length make it appropriate for deep-reach milling scenarios in ferrous and non-ferrous materials. The centercutting design allows plunge entry, expanding its utility across a range of setups in job shop and production environments.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• 0.045-inch corner radius reduces stress concentrations and improves surface finish at part edges
• 4 right-hand spiral flutes at 40-degree helix for efficient chip evacuation
• Centercutting end allows direct plunge milling without a pre-drilled pilot hole
• Bright, uncoated finish suitable for a wide range of base materials
• Single-end design with 3/4-inch shank diameter for standard ER and side-lock toolholders

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and knee mills accepting a 3/4-inch straight shank end mill.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool from the holder. Use a properly sized collet or toolholder rated for a 3/4-inch shank and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
