Accupro 310074 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The ACCUPRO 310074 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 1/4-inch cutting diameter, a 3/8-inch length of cut, and a 38-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The AlTiCrN coating provides enhanced heat and wear resistance, making this end mill well suited for high-speed cutting in hardened steels, stainless steel, and other demanding alloys. This is a single-end, right-hand cutting tool from the HS Series, ground from micrograin carbide substrate for edge consistency. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is applied in vertical and horizontal milling centers as well as manual knee mills where a 1/4-inch shank is accepted. The four-flute, variable-index geometry supports both roughing and finishing passes in ferrous and non-ferrous materials. The single-end configuration means the tool is replaced rather than reindexed when worn. It is particularly well matched to applications requiring tight tolerances in shallow-to-moderate depth-of-cut passes where rigidity and surface finish are priorities.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiCrN coating for high-temperature wear resistance in ferrous and hardened materials
• 38-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Variable index flute spacing reduces harmonic chatter during cutting
• Right-hand cutting, centercutting design allows plunge entry
• 1/4-inch shank diameter matches 1/4-inch collet and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers and manual milling machines accepting a 1/4-inch shank collet or end mill holder.

Installation Notes

Installation is performed by machinists using an appropriate collet chuck or end mill holder rated for the 1/4-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout with a dial indicator after seating to maintain dimensional accuracy. Follow machine manufacturer torque specifications for drawbar or collet nut tightening.
