Accupro 12183676 Corner Radius End Mill 5/16in 4 Flute Ticn

Product Description

The ACCUPRO 12183676 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 5/16-inch diameter, a 1-1/2-inch length of cut, and a 0.06-inch corner radius that reduces stress concentrations at part corners and extends tool life in demanding applications. The micrograin carbide substrate provides rigidity and wear resistance, while the TiCN coating adds surface hardness and lubricity. With four flutes and a right-hand spiral configuration, this end mill delivers efficient chip evacuation and smooth finishes. It is installed and operated by machinists and CNC programmers working on milling machines and machining centers.

This end mill is suited for machining ferrous and non-ferrous metals where corner radius profiles are required. The extra-long 6-inch overall length makes it appropriate for applications requiring extended reach into deep pockets, slots, or stepped features. The single-end, centercutting design allows plunge entry as well as peripheral and slot milling. Right-hand cutting direction is standard for conventional and climb milling on vertical or horizontal machining centers.

Key Features

• 0.06-inch corner radius reduces stress risers and improves surface finish at part corners
• TiCN coating provides increased surface hardness and improved wear resistance
• Micrograin solid carbide construction for rigidity and extended tool life
• Extra-long 6-inch overall length for extended reach applications
• Centercutting design allows direct plunge entry without pre-drilled holes
• Four right-hand spiral flutes for efficient chip evacuation

Compatibility

Designed for use in standard 5/16-inch collets, end mill holders, or shrink-fit toolholders on CNC machining centers and manual milling machines accepting right-hand single-end carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder runout requirements and proper clamping procedures. Ensure the spindle and toolholder are clean and free of debris before seating the shank. Verify that shank engagement meets the toolholder manufacturer minimum insertion depth to prevent pullout under cutting loads. Confirm spindle speed and feed rate parameters are appropriate for the workpiece material and coating type before beginning the cut.
