Accupro 310451 Square End Mill 3/4in 4 Flute Solid Carbide

Product Description

The ACCUPRO 310451 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built from micrograin carbide stock and coated with AlTiCrN (aluminum titanium chromium nitride), this tool handles elevated cutting temperatures and abrasive workpiece materials with extended tool life. It runs a 4-flute, single-end configuration with a 38-degree helix angle and variable index spacing, which reduces harmonic chatter during cuts. The 3/4 inch cutting diameter and 1-5/8 inch length of cut make it well suited for slotting, profiling, and peripheral milling passes at moderate-to-aggressive depths.

This end mill is intended for use in CNC machining centers and manual mills where rigidity and runout control are maintained. It is appropriate for cutting ferrous alloys, hardened steels, stainless steels, and other tough materials where standard TiN or uncoated carbide tools fall short. The right-hand cutting direction and right-hand flute spiral make it a standard spindle-forward tool for most vertical and horizontal machining setups. Machinists and toolroom technicians in job shops, production facilities, and maintenance operations are the primary users.

Key Features

• AlTiCrN coating provides high heat resistance and extended wear life in hard and abrasive materials
• Micrograin carbide substrate delivers superior rigidity and edge integrity compared to standard carbide grades
• 38-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Variable index flute spacing reduces chatter and vibration during aggressive cuts
• Centercutting design allows plunge entry into the workpiece
• Single-end geometry; 3/4 inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 3/4 inch end mill holders, collet chucks, and shrink-fit tooling systems used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the 3/4 inch shank in a properly sized end mill holder or collet and torque to the toolholder manufacturer's specification — do not rely on feel alone. Verify runout with a dial indicator before initiating cuts. Ensure the spindle is fully stopped and the machine is in a safe state before changing or inspecting tooling.
