Accupro 12182134 Corner Radius End Mill 3/4 in 3 Flute Ticn

Product Description

The ACCUPRO 12182134 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 1-1/2 inch length of cut, and a 0.02 inch corner radius that reduces stress concentrations at the base of milled features. The TiCN coating provides enhanced surface hardness and wear resistance compared to uncoated carbide. With three flutes and a 40-degree helix angle, it balances chip evacuation with cutting efficiency. Micrograin carbide construction supports tight tolerances and consistent performance across repeated cuts. This tool is installed and operated by machinists and CNC programmers working in job shops, production facilities, and toolroom environments.

This end mill is suited for milling ferrous and non-ferrous metals where a controlled corner radius profile is required at the base of pockets, slots, and stepped features. The single-end, centercutting design allows plunge entry and standard peripheral milling. The right-hand flute direction and right-hand cutting orientation match conventional CNC machining center setups. It is appropriate for both roughing and semi-finishing passes where corner radius geometry is a drawing requirement.

Key Features

• Solid micrograin carbide construction for dimensional stability and wear resistance
• TiCN coating for improved hardness and reduced tool wear on hard materials
• 0.02 inch corner radius reduces stress risers in milled pockets and slots
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design permits direct plunge entry without pre-drilling
• 3/4 inch shank diameter compatible with standard ER, Weldon, and hydraulic toolholders

Compatibility

Designed as an OEM-style replacement or direct application solid carbide end mill for CNC machining centers and manual mills using 3/4 inch diameter toolholding systems.

Installation Notes

Installation is performed by a machinist or CNC setup technician. The machine spindle must be fully stopped and the tool path program verified before mounting or changing the end mill. Secure the shank fully within the toolholder to the minimum insertion depth specified by the holder manufacturer to prevent pullout under cutting loads. Inspect the cutting edges and coating for chips or damage before use; a damaged tool should not be run at rated parameters.
