Accupro 312724 Square End Mill 3/4 in 7 Flute Carbide

Product Description

The ACCUPRO 312724 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built on the HS Series platform, it features a 3/4 inch diameter with seven flutes and a 38-degree helix angle, a combination that promotes efficient chip evacuation and surface finish quality at elevated feed rates. The AlTiCrN coating adds thermal resistance and hardness, extending tool life in ferrous and hard materials. Micrograin carbide construction provides rigidity and edge retention. This tool is installed and operated by machinists and CNC programmers in production and job-shop settings.

This end mill suits high-speed finishing and semi-finishing passes in steel, hardened steel, stainless steel, and similar ferrous alloys where coating performance and edge integrity are critical. The 1 inch length of cut (LOC) and 3/4 inch shank diameter make it well suited for rigid setups with moderate depths of cut in vertical machining centers and CNC milling machines. Right-hand cut and right-hand flute direction are standard for conventional spindle rotation. It is a single-end, non-centercutting tool.

Key Features

• AlTiCrN coating for elevated thermal resistance and extended tool life in ferrous materials
• Seven flutes for high feed rates and improved surface finish
• 38-degree right-hand helix for efficient chip evacuation
• Micrograin solid carbide substrate for rigidity and edge retention
• Single-end design with non-centercutting geometry
• Matching 3/4 inch mill diameter and shank diameter for direct ER or end mill holder fitment

Compatibility

Designed as an OEM-style replacement or standard production end mill for CNC vertical machining centers and milling machines accepting a 3/4 inch straight shank end mill holder or collet chuck.

Installation Notes

This tool is installed by machinists using an appropriate end mill holder, collet chuck, or shrink-fit toolholder rated for 3/4 inch shank diameter. Ensure the holder is clean and free of chips before seating the shank to full engagement depth. Verify spindle runout is within acceptable tolerance before cutting to protect the cutting edge. Follow machine tool manufacturer guidelines for maximum spindle speed and feed rate for the workpiece material and depth of cut.
