Accupro 12183533 Corner Radius End Mill 3/8 in 4 Flute Ticn

Product Description

The ACCUPRO 12183533 is a single-end, centercutting corner radius end mill designed for precision milling in ferrous and hard materials. Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), it delivers hardness and wear resistance in demanding cutting environments. The tool features a 3/8 inch diameter, a 1/8 inch corner radius, a 1 inch length of cut, and a 4 inch overall length. Four right-hand spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth surface finishes. This end mill is installed and used by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This end mill is suited for slot milling, profiling, and corner-radius contouring in applications where a blended radius is required at the base of a feature. The long-length configuration and 3/8 inch shank diameter make it appropriate for reaching deeper pockets while maintaining rigidity. Typical applications include die and mold work, aerospace component machining, and general job-shop operations on steel, stainless steel, and cast iron. The TiCN coating extends tool life in abrasive and high-temperature cutting conditions.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating for improved hardness and heat resistance in ferrous materials
• 1/8 inch corner radius blends vertical walls to floor radii in a single pass
• 4-flute, right-hand spiral design with 40-degree helix for efficient chip removal
• Centercutting capability allows direct plunge entry into the workpiece
• Long-length configuration with 1 inch length of cut and 4 inch overall length

Compatibility

Designed as an OEM-style solid carbide corner radius end mill suitable for use in standard 3/8 inch collets and end mill holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully into a clean, undamaged collet or end mill holder and torque to the holder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use. Follow all machine guarding and PPE requirements per shop safety standards.
