Accupro 12183511 Corner Radius End Mill 5/16 in 4 Flute Ticn

Product Description

The ACCUPRO 12183511 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 5/16 inch diameter, a 0.06 inch corner radius, and a TiCN (Titanium Carbonitride) coating that increases surface hardness and reduces built-up edge during cutting. With 4 flutes and a right-hand spiral flute direction, it delivers efficient chip evacuation and a consistent finish. Micrograin carbide construction provides rigidity and wear resistance in demanding cutting conditions. This tool is intended for use by machinists and tooling professionals running CNC or manual milling equipment.

The 12183511 is suited for profiling, slotting, and peripheral milling applications where a radiused corner is required to reduce stress concentrations in the workpiece. The 1 inch length of cut and 4 inch overall length make it well matched to medium-depth passes in steel, stainless, cast iron, and similar materials. Its centercutting capability allows plunge entry, adding flexibility in CNC machining centers and manual knee mills alike. The long flute length designation and single-end configuration are standard for general-purpose toolpath work in production and job-shop environments.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life
• TiCN coating reduces friction and resists built-up edge in ferrous materials
• 0.06 inch corner radius minimizes stress risers and improves part geometry
• Centercutting design permits direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand spiral for standard CNC spindle compatibility
• Single-end, 4-flute configuration balances chip clearance with surface finish quality

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 5/16 inch collets, end mill holders, or shrink-fit tooling systems on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 5/16 inch shank fully into the collet or holder to the recommended engagement depth before torquing the retention mechanism. Verify runout with a dial indicator before initiating a cut, as excessive runout will accelerate wear and degrade corner radius accuracy.
