Accupro 312353 Square End Mill 3/4 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 312353 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built to Series HS specifications, it features a 3/4-inch diameter, a 1-inch length of cut, and five flutes with a 38-degree helix angle. The AlTiCrN coating provides heat and wear resistance at elevated cutting temperatures, making this tool well-suited for hard materials and aggressive feed rates. Variable index flute spacing reduces chatter and improves surface finish. The single-end design and right-hand cutting direction are standard for general milling operations on CNC machining centers and manual mills.

This end mill is intended for professional machinists working on production and job-shop applications. It handles ferrous and hardened materials where thermal resistance and edge retention are priorities. The extended reach configuration, with a 3.375-inch reach length and 6-inch overall length on a 3/4-inch shank, allows access to deeper pockets and shoulders without requiring specialty toolholders. Micrograin carbide construction supports tight tolerances and consistent performance across high-volume runs.

Key Features

• AlTiCrN coating for high heat resistance and extended tool life in hard materials
• 5-flute design with variable index for reduced vibration and improved surface finish
• 38-degree helix angle optimized for aggressive material removal
• Center-cutting capable for plunge entry into workpiece
• Extended reach at 3.375 inches for deep pocket and shoulder milling
• Micrograin solid carbide construction for edge stability and precision

Compatibility

Designed as a direct-fit replacement for Series HS solid carbide square end mills with a 3/4-inch shank diameter. Compatible with standard ER and side-lock toolholders accepting 3/4-inch shank tooling on CNC machining centers and knee mills.

Installation Notes

Installation is performed by qualified machinists following standard toolholder torque and runout procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify toolholder bore cleanliness and shank seating before tightening. Follow the machine tool manufacturer guidelines for maximum RPM and feed rate recommendations when using coated carbide end mills.
