Accupro 12182126 Corner Radius End Mill 3/4 in 3 Flute

Product Description

The ACCUPRO 12182126 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 3/4 inch diameter cutting head with a 0.03 inch corner radius, a 1-1/2 inch length of cut, and a 4 inch overall length. The three-flute, right-hand spiral design with a 40-degree helix angle promotes efficient chip evacuation and stable cutting performance. The bright uncoated finish suits a range of ferrous and non-ferrous workpiece materials. This tool is installed and operated by machinists and tooling professionals in CNC and manual milling applications.

This end mill is suited for slotting, profiling, and peripheral milling where a controlled corner radius is required to reduce stress concentrations in the finished part. The centercutting geometry allows for plunge entry without a pre-drilled pilot hole. The micrograin carbide substrate provides edge retention in demanding cuts. It is a single-end tool, meaning the cutting end is not reversible, and the 3/4 inch shank diameter is sized for standard collet and end mill holder setups common in vertical and horizontal machining centers.

Key Features

• 0.03 inch corner radius reduces sharp corners and improves part strength at milled profiles
• 3 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry enables direct plunge entry
• Micrograin solid carbide construction for extended tool life and edge integrity
• Bright uncoated finish suitable for a broad range of workpiece materials
• Single-end design with matched 3/4 inch shank and cutting diameter

Compatibility

Designed as an OEM-style replacement or direct tooling selection for standard 3/4 inch collet chucks, end mill holders, and milling machine spindles accepting 3/4 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully powered down and locked before inserting or removing the tool from the holder. Verify collet or holder bore cleanliness and confirm proper seating depth before tightening. Do not exceed the tool manufacturer recommended feed and speed parameters for the workpiece material.
