Sandvik Coromant 8038693 Corner Radius End Mill 1/2in 3FL

Product Description

The SANDVIK COROMANT 8038693 is a solid carbide corner radius end mill from the CoroMill Dura series, designed for high-performance milling in metalworking and machining applications. It features a 1/2 inch diameter, a 0.03 inch corner radius, and three flutes with variable helix and variable index geometry. The ZrN (zirconium nitride) coating improves wear resistance and surface finish. With a right-hand cutting direction and centercutting capability, this end mill handles both ramping and plunging operations. It is installed and operated by CNC machinists and tool and die professionals working on vertical and horizontal machining centers.

This end mill is suited for milling nonferrous materials, consistent with its N1BZ material grade designation. Typical applications include finishing and semi-finishing passes on aluminum alloys and other nonferrous metals where edge integrity and surface quality are priorities. The 5/8 inch length of cut and 4 inch overall length make it appropriate for moderate-depth slot milling, profiling, and contouring operations in production and job-shop environments.

Key Features

• Variable helix and variable index geometry reduce harmonic vibration during high-speed milling
• ZrN coating provides wear resistance and reduced built-up edge on nonferrous materials
• Centercutting design allows direct plunge entry and ramping operations
• Solid carbide construction delivers rigidity and dimensional stability under cutting loads
• Right-hand spiral flutes with straight-cylindrical shank for standard collet and end mill holder mounting
• CoroMill Dura series engineered for consistent tool life in production-volume applications

Compatibility

Designed as an OEM-style replacement or direct application end mill for machining centers accepting 1/2 inch straight-cylindrical shank tooling. Material grade N1BZ designates suitability for nonferrous workpiece materials per SANDVIK COROMANT classification.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Secure the 1/2 inch shank in a precision collet chuck or end mill holder per machine tool manufacturer torque guidelines before operation. Confirm spindle direction is set to right-hand rotation before running. Do not exceed the rated length of cut of 5/8 inch without consulting cutting data recommendations for the specific workpiece material.
