Accupro 14788548 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The ACCUPRO 14788548 is a solid carbide corner radius end mill designed for precision milling operations in demanding shop environments. It features a 0.75 inch diameter with a 0.1300 inch corner radius, reducing stress concentrations at the cutting edge and extending tool life in hardened and abrasive materials. The 4-flute, right-hand spiral design delivers efficient chip evacuation and a smooth surface finish. An AlTiN+ coating provides high heat resistance and wear protection, making this end mill well-suited for dry or high-speed cutting of ferrous alloys, stainless steel, and hardened steels. Machinists and CNC operators working in precision manufacturing and tool-and-die applications are the primary users.

This end mill is built for single-end use in vertical and horizontal CNC machining centers. With a 2.25 inch length of cut and a 5 inch overall length, it handles deep-cavity milling, profiling, and contouring passes where reach and rigidity both matter. The centercutting geometry allows plunge entry directly into the workpiece, adding flexibility for slotting and pocket milling operations. It is a single-end tool, so once the cutting end is worn, the tool is replaced rather than reindexed.

Key Features

• 0.1300 inch corner radius reduces edge chipping and stress cracking in hardened materials
• AlTiN+ coating delivers superior oxidation resistance for high-speed and dry cutting
• 4-flute spiral geometry supports high feed rates and improved surface finish
• Centercutting design enables direct plunge entry for slotting and pocket work
• Solid carbide construction provides rigidity and dimensional stability under heavy cutting loads
• Right-hand cutting direction compatible with standard CNC spindle rotation

Compatibility

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

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the tool holder and torque the retention hardware per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut to avoid premature tool wear or workpiece damage.
