CoroMill 490

CoroMill® 490 is the first cutter with true 90 degree cuts without sharp steps. It uses four-edge inserts with light cutting action, a result of innovative insert geometry in combination with new generation, high performance grades. Inserts require less force for cutting and generates a smoother profile for less finishing.

Benefits

• A standard milling tool that gives lower tool costs and inventories
• Great flexibility, high precision and good tolerances
• Light and quiet cutting with low force
• High productivity with outstanding insert geometry and new grades
• Sharp edge lines and burr-free, smoother profiles
• Product finished in one pass
• True 90-degree cut without sharp steps

Features

• Light cutting performance provides an optimal utilization of less-powered machine tools. This feature also facilitates use of the cutter on extended tool assemblies
• Undersized shanks for larger diameter cutters, using 8 mm (0.315 inch) inserts, allow these to fit into smaller tool holders
• Oversized versions of CoroMill 490 enhance the accessibility and provide natural clearance to tight fixtures
