Seco 03080249 Indexable Insert Drill 28mm 4xd

Product Description

The SECO 03080249 is a 28mm diameter indexable insert drill built for general-purpose drilling in metal-cutting applications. It accepts two indexable inserts and uses a modular connection with a C5 interface, making it compatible with the SD524 drill body series. The drill achieves a maximum depth of 112mm at a 4xD depth-to-diameter ratio, with a flute length of 117mm. The body is constructed from steel and features axial concentric coolant-through entry to support chip evacuation and tool life in production drilling. This tool is installed and operated by machinists and CNC programmers working in job shop or production environments.

This drill is designed for general-purpose drilling operations where a modular, indexable-insert platform is preferred over brazed or solid carbide tooling. The 4xD ratio suits through-hole and blind-hole applications in a range of workpiece materials. The modular C5 connection allows the body to be mounted to compatible toolholders and machine spindles. Coolant-through capability supports higher feed rates and extended insert life in both horizontal and vertical machining setups.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable insert tooling and CNC or manual machine setup. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or changing inserts. Verify the C5 modular connection is properly seated and torqued per the machine tool manufacturer specifications before running. Confirm coolant-through passages are clear and coolant supply is active before engaging the cut.
