Accupro 14797577 Corner Radius End Mill 1/8 Inch 4 Flute

Product Description

The ACCUPRO 14797577 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and tight tolerances. Built on a miniature series platform, this single-end tool features a 1/8 inch cutting diameter and a 0.0100 inch corner radius, making it well-suited for fine detail work in hard and abrasive materials. The 4-flute geometry and 30-degree helix angle promote efficient chip evacuation and surface finish quality. An AlTiN coating extends tool life in dry and high-temperature cutting environments. Centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

This end mill is used in CNC machining centers, die and mold work, and high-precision component manufacturing where small-diameter tooling is required. The miniature series designation suits applications in aerospace, medical device, and precision instrument sectors where tight corner radii and dimensional accuracy are critical. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle setups. The 1/2 inch length of cut and 1-1/2 inch overall length position this tool for shallow-to-moderate depth passes in confined features and pockets.

Key Features

• 0.0100 inch corner radius reduces stress concentration and improves edge integrity on finished parts
• AlTiN coating provides oxidation resistance and hardness retention at elevated cutting temperatures
• 4-flute spiral design balances chip load, feed rate capability, and surface finish
• 30-degree helix angle improves chip flow and reduces cutting forces in small-diameter applications
• Centercutting geometry allows direct plunge milling without a pilot hole
• Micrograin solid carbide substrate delivers rigidity and wear resistance in hard workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use miniature corner radius end mill for CNC machining setups requiring a 1/8 inch shank and 1/8 inch cutting diameter with a 0.0100 inch corner radius.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. The 1/8 inch shank should be seated in a collet or tool holder that matches shank diameter tolerance to prevent runout. Verify shank diameter tolerance of -0.0001 to -0.0003 inches is within holder specification before use.
