Accupro 12183473 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 12183473 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 1 inch length of cut, and a 0.015 inch corner radius that reduces stress concentration at the cutting edge and extends tool life on hardened and abrasive workpiece materials. The 4-flute, right-hand spiral geometry provides efficient chip evacuation and a smooth finish. Micrograin carbide construction delivers consistent performance in demanding cutting conditions. This tool is intended for use by machinists and tool-and-die professionals working on CNC mills and manual milling machines.

This end mill is suited for finish milling, profiling, and contouring operations in ferrous and non-ferrous materials where a radiused corner is required. The bright/uncoated finish makes it appropriate for applications where coating interaction with the workpiece or cutting fluid is a concern. Its single-end, centercutting design allows plunge entry as well as peripheral and slot milling. The long-length configuration and 4 inch overall length provide added reach for deeper pockets and stepped features.

Key Features

• 0.015 inch corner radius reduces edge chipping and stress risers on milled corners
• Micrograin solid carbide construction for rigidity and wear resistance
• 4-flute right-hand spiral for smooth surface finish and efficient chip removal
• Centercutting design allows direct plunge entry into workpiece material
• Bright/uncoated finish suitable for use with a wide range of cutting fluids
• Long-length body with 4 inch overall length for extended reach applications

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC and manual milling machines accepting a 1/4 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Ensure the spindle and collet are clean and free of debris before seating the shank. Verify tool runout at the tip with a dial indicator before beginning a cut. Do not exceed the tool's rated depth of cut or feed rate for the workpiece material.
