Accupro 14797589 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 14797589 is a solid carbide corner radius end mill designed for precise milling operations requiring a controlled edge radius. With a 0.25 inch mill diameter and a 0.0600 inch corner radius, this tool produces smooth transitions and reduces stress concentrations at part corners. The 4-flute, right-hand spiral geometry delivers clean chip evacuation and consistent surface finish. At 2.5 inches overall length with a 0.75 inch length of cut, this miniature-series tool is well suited for close-tolerance work in tight cavities and fine-detail profiling. Machinists and toolroom technicians working with CNC machining centers and manual mills will find this a reliable everyday cutting tool.

This end mill is built for light-to-medium duty milling in ferrous and non-ferrous materials where corner geometry must be held consistently. The miniature series designation makes it appropriate for small-part machining, die work, and mold detail work where a full-size end mill cannot be used. The bright uncoated finish makes it straightforward to inspect for wear. Right-hand cutting direction and centercutting capability allow it to be used for both peripheral and plunge milling operations.

Key Features

• Solid carbide micrograin construction for rigidity and edge retention in fine-detail cuts
• 0.0600 inch corner radius reduces corner chipping and part stress concentrations
• 4-flute right-hand spiral geometry for efficient chip evacuation and surface finish
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Bright uncoated finish simplifies wear inspection and suits a wide range of base materials
• Miniature series at 0.25 inch diameter for small-part, die, and mold detail applications

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 0.25 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the 0.25 inch shank fully and evenly in a properly sized collet or end mill holder, and verify runout before beginning a cut. Do not exceed the manufacturer-recommended feed and speed parameters for the workpiece material and depth of cut.
