Seco 02703393 Indexable Grooving Toolholder Mdt Series

Product Description

The SECO 02703393 is an external right hand indexable grooving toolholder designed for precise groove machining on CNC lathes and turning centers. Built to the CFS toolholder style within SECO's Multi-Directional Turning (MDT) series, it accepts LC.. 1603.. series inserts secured by a clamp-style insert holding method. The toolholder delivers a maximum depth of cut of 0.95 inches and a minimum groove width of 3mm (0.1181 inches), making it well suited for tight-tolerance external grooving on stainless steel and similarly demanding workpiece materials. Overall length is 6 inches with a 1 inch by 1 inch square shank.

This toolholder is intended for external, non-face grooving operations in professional machining environments. Its right-hand cutting direction suits standard lathe setups where tooling is mounted conventionally. The primary workpiece material designation is stainless steel (ISO material code M), though the MDT platform is broadly applicable to precision turning work requiring repeatable groove geometry. Machinists in production and job-shop settings will find the 4.19-inch shank length and 1.81-inch head length compatible with standard tool blocks and quick-change systems on mid-to-large turning centers.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before mounting or changing tooling per standard lockout/tagout procedures. Ensure the shank seating surfaces and tool block bore are clean and free of chips before clamping. Inserts must be indexed or replaced with the spindle fully stopped; never attempt insert changes with the machine in motion.
