Accupro 14788499 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The ACCUPRO 14788499 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/4 inch (0.7500 inch) mill diameter, a 1-1/2 inch (1.5000 inch) length of cut, and a 0.1300 inch corner radius that reduces stress concentrations and extends tool life at the cutting edge. The 4-flute, right-hand spiral design promotes efficient chip evacuation and smooth surface finishes. An AlTiN+ coating provides enhanced heat resistance and hardness at elevated cutting temperatures, making this end mill well-suited for ferrous and hardened materials. Installed by machinists and CNC operators, this single-end, centercutting tool can plunge directly into workpiece material.

This end mill is intended for use in CNC machining centers and manual milling machines where a corner radius profile is required to produce radiused inside corners, improve part strength, or meet engineering drawing callouts. It is appropriate for production and toolroom environments working with steel, stainless steel, cast iron, and similar hard materials. The centercutting geometry allows for slot milling and plunge cuts without pre-drilling. With a 4 inch overall length and a 3 inch shank diameter, it is sized for rigid, high-reach setups.

Key Features

• 0.1300 inch corner radius reduces stress risers and extends cutter life at corners
• AlTiN+ coating improves heat resistance and wear performance in hard and ferrous materials
• 4-flute right-hand spiral geometry for efficient chip evacuation and surface finish quality
• Centercutting design permits direct plunge entry without pre-drilling
• Solid carbide construction provides rigidity and dimensional stability at high cutting speeds
• Single-end configuration with 4 inch overall length for extended-reach applications

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in CNC machining centers and manual mills accepting a 3 inch shank diameter collet or holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into a properly sized collet or end mill holder and tighten to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, and confirm that feed rate, spindle speed, and depth of cut are appropriate for the workpiece material and machine capability.
