Accupro 14788498 Corner Radius End Mill 3/4 in 4 Flute Carbide

Product Description

The ACCUPRO 14788498 is a single-end, centercutting corner radius end mill designed for precision milling of ferrous and hard materials in machining centers and CNC mills. Built from solid carbide with an AlTiN+ coating, it offers a 0.75 inch mill diameter, a 1.5 inch length of cut, and a 0.0100 inch corner radius. The four-flute spiral design promotes chip evacuation and surface finish quality. At 4 inches overall length, this tool suits deep-reach pocketing and profiling operations where rigidity and coating durability are critical. It is installed and run by machinists and CNC operators in production and job-shop environments.

This end mill is suited for milling steel, stainless steel, cast iron, and other hard alloys in both roughing and finishing passes. The AlTiN+ coating significantly increases surface hardness and heat resistance, making it effective in dry or minimal-lubrication cutting conditions. The centercutting geometry allows plunge milling directly into the workpiece. Typical applications include die and mold work, contour profiling, slot milling, and pocketing where a tight corner radius is specified on the part print.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN+ coating provides high heat resistance and extended tool life in dry cutting
• 0.0100 inch corner radius reduces stress concentration and improves edge strength
• Four-flute spiral geometry balances chip evacuation with surface finish quality
• Centercutting design permits direct plunge entry without pre-drilling
• Right-hand cutting direction with single-end configuration for standard CNC toolholding

Compatibility

Designed as a standard-shank solid carbide end mill compatible with CNC machining center toolholders accepting a 3 inch shank diameter. Verify runout and holder condition before use.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool path is cleared before changing tooling. Secure the shank fully in the toolholder to the manufacturer-specified engagement depth and verify runout with a dial indicator before production cuts. Inspect the cutting edges for chips or wear before each use and do not exceed recommended feeds and speeds for the workpiece material and coating type.
