Accupro 12183437 Corner Radius End Mill 1in 4 Flute Ticn

Product Description

The ACCUPRO 12183437 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous metals. Built from micrograin carbide and finished with a TiCN coating, it delivers extended tool life in demanding cutting environments. The 4-flute, right-hand spiral configuration with a 40-degree helix promotes efficient chip evacuation and smooth surface finishes. At 1 inch in diameter with a 0.09-inch corner radius, it produces accurate radiused profiles while reducing edge chipping. Centercutting geometry allows direct plunge entry without a pre-drilled start hole. This tool is installed and operated by machinists and CNC tooling professionals in production and job-shop settings.

This end mill is suited for long-reach milling applications requiring a full 2-inch length of cut and 6-inch overall length. The single-end, long-length construction makes it appropriate for deep-pocket and side-wall milling operations where standard-length tooling cannot reach. The 1-inch shank diameter provides solid rigidity and reduces deflection during heavy cuts. The TiCN coating improves wear resistance and is well-matched for use in alloy steels, stainless steels, and cast iron. Typical applications include mold and die work, aerospace components, and general precision machining.

Key Features

• Micrograin solid carbide substrate for increased hardness and wear resistance
• TiCN coating for extended tool life in ferrous and hard materials
• 0.09-inch corner radius reduces stress concentration and edge chipping at workpiece corners
• 4-flute, 40-degree right-hand helix for efficient chip removal and surface finish quality
• Centercutting design permits direct plunge cutting without pilot hole
• Long-length geometry with 2-inch LOC and 6-inch OAL for deep-pocket access

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual mills accepting a 1-inch straight shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Use a properly sized end mill holder or precision collet rated for a 1-inch shank to achieve the manufacturer shank diameter tolerance range. Verify tool runout with a dial indicator after clamping before beginning any cut, and confirm feeds and speeds are appropriate for the workpiece material before operation.
