Accupro 14788547 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 14788547 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard materials. It features a 5/8 inch (0.6250 inch) cutting diameter with a 0.0100 inch corner radius that reduces edge chipping and extends tool life at pocket floors and wall transitions. The 4-flute, right-hand spiral geometry provides efficient chip evacuation and a smooth finish. An AlTiN+ coating adds thermal resistance and hardness for high-speed and dry machining applications. This tool is installed by machinists and CNC operators in production and job-shop environments.

This end mill is suited for use in vertical and horizontal machining centers as well as manual knee mills where a single-end, centercutting tool is required. The 2.125 inch length of cut accommodates moderate-depth pockets and slots, while the 4.630 inch overall length allows reach into recessed features. Its centercutting design permits plunge entry. Typical applications include profiling, slotting, and contouring in steel, stainless steel, cast iron, and similar materials where an AlTiN+ coating provides thermal and wear performance advantages.

Key Features

• 0.0100 inch corner radius reduces stress concentration and prevents edge breakout at pocket corners
• AlTiN+ coating provides elevated hardness and oxidation resistance for high-speed and dry cutting
• 4-flute right-hand spiral geometry balances material removal rate with surface finish quality
• Centercutting design allows direct plunge entry without pre-drilling
• Solid carbide construction delivers rigidity and dimensional stability under aggressive feed rates
• Single-end configuration with 2.125 inch length of cut suitable for moderate-depth features

Compatibility

Designed as a standard shank solid carbide corner radius end mill compatible with ER, milling chuck, and hydraulic toolholders accepting a 5/8 inch shank diameter, as commonly used in CNC machining centers and manual mills.

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 to the correct depth in the toolholder per the toolholder manufacturer's specifications and torque the retention mechanism accordingly. Verify runout with a dial indicator after installation before beginning a cut, as excessive runout will accelerate wear and reduce dimensional accuracy.
