Seco 03277879 Indexable Slotting Cutter 2in Combimaster

Product Description

The SECO 03277879 is an indexable slotting cutter designed for slotting, side milling, and disc milling operations on CNC machining centers and manual milling machines. Part of the R335.19 series, it features a 2 inch cutter diameter with a 0.25 inch cutting width and delivers a maximum depth of cut of 0.6020 inches. The cutter uses a Combimaster modular connection with an M12 modular connection size, allowing quick tool changes without removing the arbor. It accepts 2 SNHQ-style inserts held by screw clamping and is rated for a maximum spindle speed of 12,300 RPM. Installation is performed by qualified machinists and tooling specialists.

This cutter is suited for general-purpose slotting and side milling in a range of workpiece materials. The staggered tooth configuration with negative axial and negative radial rake geometry supports stable cutting action and predictable chip formation. The 4-tooth, coolant-through design makes it appropriate for both dry and wet cutting environments where through-spindle coolant is available. It is well matched to production and job shop environments running standard vertical or horizontal machining centers equipped with a Combimaster-compatible toolholder.
