Accupro 12183147 Corner Radius End Mill 3/4 in 4 Flute Ticn

Product Description

The ACCUPRO 12183147 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/4 inch diameter, a 2-1/4 inch length of cut, and a 0.045 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding materials. The 5 inch overall length and long-reach geometry make it suitable for deeper cavity and profile work. A TiCN coating provides increased surface hardness and lubricity for improved wear resistance. This tool is used by machinists and CNC operators working in job shops, production facilities, and toolrooms.

This end mill is well suited for side milling, slotting, and profiling operations in steel, stainless steel, cast iron, and other ferrous materials where corner radius geometry is required. The single-end, center-cutting configuration allows for both plunge entry and lateral cutting passes. The 40-degree helix angle promotes efficient chip evacuation and reduces chatter during full-depth passes. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC machining center setups.

Key Features

• 0.045 inch corner radius reduces edge chipping and stress risers on workpiece corners
• TiCN coating improves hardness and wear resistance compared to uncoated carbide
• Micrograin solid carbide substrate supports higher feed rates and longer tool life
• 4-flute, 40-degree helix design balances chip load and surface finish
• Center-cutting capability allows direct plunge entry without a pilot hole
• Long-length geometry at 5 inches OAL accommodates deep pocket and profile work

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3/4 inch straight shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the 3/4 inch shank in a matching end mill holder or collet to the appropriate pull-out force per machine tool manufacturer guidelines. Ensure the spindle and tool changer are fully stopped and the machine is in an E-stop or lockout state before inserting or removing the tool. Do not exceed the tool manufacturer recommended depth of cut or radial engagement for the material being machined.
