Accupro 12181343 Corner Radius End Mill 1/4 in 2 Flute Ticn

Product Description

The ACCUPRO 12181343 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 1/4 inch mill diameter, a 3/4 inch length of cut, and a 0.06 inch corner radius for consistent edge blending and reduced stress concentration at part corners. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating adds surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC programmers on vertical machining centers and manual mills.

This end mill is suited for finish milling, profiling, and contouring applications where a radiused corner is required. The centercutting geometry allows for plunge entry as well as standard peripheral cuts. Its single-end, right-hand cut and right-hand flute direction make it compatible with conventional milling setups. The 2-flute configuration provides wider chip clearance, making it a practical choice for slotting and pocketing in softer metals and plastics as well as light cuts in harder alloys.

Key Features

• 0.06 inch corner radius reduces stress risers and improves surface finish at part corners
• TiCN coating provides enhanced hardness and wear resistance over uncoated carbide
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting forces
• Micrograin solid carbide substrate delivers rigidity and edge retention
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand spiral flute direction for standard spindle operation

Compatibility

Designed as an OEM-style replacement or direct-use corner radius end mill for standard 1/4 inch collet or end mill holders on vertical machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or end mill holder matched to the 1/4 inch shank diameter, and confirm tool projection and runout with a dial indicator before beginning a cut. Follow applicable shop safety standards for rotating cutting tools, including appropriate guarding and PPE.
