Seco 02422260 Indexable Chamfer End Mill 1.38in Quattromill

Product Description

The SECO 02422260 is an indexable chamfer end mill designed for precision milling operations in metal cutting environments. Built around the QuattroMill platform, this tool accepts three SE.. 09T3 style inserts secured by screw clamping, providing stable cutting at a 45-degree lead angle. The cutting diameter ranges from 0.98 inches minimum to 1.38 inches maximum, with a maximum depth of cut of 0.18 inches. Rated to 22,400 RPM, it suits high-speed finishing and chamfering passes on CNC machining centers. The Weldon flat shank provides positive drive engagement and resists pullout under demanding feed conditions. Licensed machinists and CNC tooling technicians are the primary installers and operators of this tool.

This end mill is suited for milling chamfers, bevels, and angled features on ferrous and non-ferrous workpieces in job shop, production, and aerospace machining environments. It mounts in toolholders conforming to the R217.53 style and is compatible with machining centers equipped with coolant-through spindle capability. The Weldon flat shank accommodates standard side-lock holders with 3/4 inch bore size. This configuration is typical in operations requiring repeatable insert indexing without full tool replacement.
