Accupro 14797554 Corner Radius End Mill 0.055in 4 Flute

Product Description

The ACCUPRO 14797554 is a solid carbide corner radius end mill designed for precision milling in tight-tolerance and miniature applications. With a 0.055 inch cutting diameter and a 0.015 inch corner radius, it produces smooth transitions between floor and wall surfaces while reducing stress concentrations at the cutting edge. The 4-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation. An AlTiN coating extends tool life in harder workpiece materials by improving heat and abrasion resistance. Machinists and tool-and-die professionals working on CNC mills will find this end mill well-suited for fine detail work in hardened steels and other demanding materials.

This end mill is built for miniature-series applications where small-diameter cutters are required. It is a single-end, centercutting design, meaning it can be fed axially into a workpiece as well as in standard peripheral or slot milling operations. With a 1.5 inch overall length and a 0.125 inch shank diameter, it fits standard miniature toolholders and collets. The 0.165 inch length of cut makes it appropriate for shallow pockets, slots, and contour work in precision machined components.

Key Features

• 0.055 inch cutting diameter with tight mill diameter tolerance of +0.000000 / -0.001000 inches
• 0.015 inch corner radius reduces edge chipping and extends surface finish quality
• AlTiN coating for elevated heat resistance and longer tool life in hard materials
• 4 right-hand spiral flutes with 30-degree helix for efficient chip removal
• Centercutting design allows axial plunge entry
• Micrograin solid carbide construction provides rigidity and wear resistance in miniature-scale cuts

Compatibility

Designed as an OEM-style miniature series corner radius end mill for use in standard CNC machining centers and manual mills equipped with collet toolholders accepting a 0.125 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the shank to the specified depth in a clean, undamaged collet or toolholder to maintain runout accuracy. Verify that feed rate and spindle speed are set appropriately for the workpiece material and tool diameter before initiating a cut.
