Accupro 315677 Corner Radius End Mill 3/4 in Solid Carbide

Product Description

The ACCUPRO 315677 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 3/4 inch (0.7500 inch) mill diameter, a 1 inch length of cut, and a 6 inch overall length with extended reach capability. The cutting geometry uses a 3-flute, right-hand spiral flute design with a 37-degree helix angle and a 0.1200 inch corner radius. A ZrN (zirconium nitride) coating improves wear resistance and surface finish in a range of ferrous and non-ferrous materials. This tool is centercutting, allowing plunge entry. It is intended for use by machinists and CNC operators in production and job-shop environments.

This end mill is suited for peripheral and slot milling operations where a corner radius is required to reduce stress concentration at part edges. The extended reach design, with a 3.375 inch reach length and 0.7125 inch neck diameter, allows access to deep pockets and features that standard-length tools cannot reach. It is used in machining centers and CNC mills running right-hand cutting operations on parts requiring tight dimensional tolerances.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating for improved tool life in abrasive and hard materials
• 3-flute right-hand spiral geometry with 37-degree helix angle
• 0.1200 inch corner radius reduces edge chipping and part stress risers
• Centercutting design allows direct plunge entry
• Extended reach with 3.375 inch reach length for deep-pocket access

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 3/4 inch shank diameter toolholder.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Use a calibrated toolholder suited for a 3/4 inch shank and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator after seating before commencing a cut.
