Accupro 12184997 Square End Mill 4-flute 0.75 in Altin Carbide

Product Description

The ACCUPRO 12184997 is a 4-flute solid carbide square end mill designed for both roughing and finishing operations in a single tool. It features an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life in high-temperature cutting applications. The 40-degree helix angle promotes aggressive chip evacuation and smooth cutting action. With a 0.75 inch cutting diameter, a 1.5 inch length of cut, and a 4 inch overall length, this end mill suits a wide range of milling operations on ferrous and non-ferrous materials. A chipbreaker geometry on the flutes reduces cutting forces during roughing passes while still leaving a finish-ready surface.

This end mill is intended for use in CNC machining centers and manual mills where a single tool must handle both material removal and surface finishing. Its single-end, right-hand cut, right-hand flute design makes it a standard fit for conventional and climb milling setups. It is well suited for tool and die shops, production machining, aerospace component work, and general metalworking applications where cycle time reduction through combined roughing and finishing passes is a priority.

Key Features

• Solid carbide construction provides rigidity and wear resistance across a wide range of workpiece materials
• AlTiN coating enhances thermal resistance for dry or high-speed machining environments
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Chipbreaker geometry enables roughing and finishing in a single tool pass
• Right-hand cut and right-hand flute direction for standard CNC and manual mill compatibility
• 0.75 inch shank diameter matches common collet and end mill holder sizes

Compatibility

Designed as a standard 0.75 inch shank solid carbide end mill compatible with ER collets, end mill holders, and hydraulic chuck systems accepting a 0.75 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Use a properly sized collet or end mill holder with adequate pull-out retention for the 0.75 inch shank, and verify runout with a dial indicator before beginning a cut. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
