Accupro 12180367 Corner Rounding End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12180367 is a double-end corner rounding end mill designed for profiling and edge-breaking operations on metal workpieces. Built from solid carbide with a TiCN (titanium carbonitride) coating, it provides high wear resistance and extended tool life in demanding machining environments. The cutter features a 0.02 inch corner radius, a 3/16 inch mill diameter, and four right-hand flutes for efficient chip evacuation. With an overall length of 2 inches and a matching 3/16 inch shank diameter, it fits standard collet toolholding systems. Machinists and CNC operators in job shops and precision manufacturing facilities are the primary users of this tool.

This end mill is suited for corner rounding and edge contouring on ferrous and non-ferrous metals. The double-end configuration delivers two usable cutting ends per tool, reducing per-edge tooling cost in production environments. The 0.02 inch radius produces a small, controlled radius break on edges and shoulders, making it appropriate for finishing passes on tight-tolerance components. Right-hand cutting and flute direction are standard for conventional CNC milling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in metal cutting
• TiCN coating reduces friction and extends tool life compared to uncoated carbide
• Double-end design provides two cutting edges per tool
• 0.02 inch corner radius for precise, small-radius edge contouring
• 4 right-hand flutes with right-hand cutting direction for standard CNC milling
• 3/16 inch shank diameter fits standard collet and toolholding systems

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collet toolholding systems that accept a 3/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into the collet or toolholder and torque to the toolholder manufacturer's specification before running. Confirm spindle direction is set to right-hand rotation before engaging the cut. Inspect the cutting edges for chips or wear before each use, particularly on the double-end style where the second end may have been previously used.
