Seco 02422261 Indexable Chamfer End Mill 1.65in Quattromill

Product Description

The SECO 02422261 is an indexable chamfer end mill designed for professional milling applications in metalworking and machining operations. Built on the QuattroMill platform, it accepts four SE.. 09T3 style inserts secured by screw clamp, delivering stable, repeatable cutting performance across a wide range of materials. Key specs include a maximum cutting diameter of 1.65 inches, a 3/4 inches Weldon Flat shank for secure machine spindle retention, and a maximum depth of cut of 0.18 inches. With a 45-degree lead angle, this toolholder is suited to chamfering, beveling, and angled face milling operations. Licensed machinists and CNC setup techs are the primary installers of this tool.

The 02422261 is used in CNC machining centers and manual milling machines where precise chamfer geometry is required. Its Weldon Flat shank fits standard side-lock toolholders commonly found in both horizontal and vertical milling setups. The toolholder style is R217.53, and the tool is compatible with coolant-through delivery, making it suitable for higher-speed operations or harder workpiece materials where heat management is critical. Typical applications include chamfering bored holes, part edges, and mating surfaces in production or job-shop environments.
