Seco 00013360 Msdn Neutral Indexable Turning Toolholder

Product Description

The SECO 00013360 is an MSDN-style neutral-hand indexable turning toolholder designed for use on metal-cutting lathes and turning centers. It features a 1 inch by 1 inch square shank and an overall length of 6 inches, making it a standard-size holder suited to a wide range of engine lathe and CNC turning applications. The holder uses a clamp-and-pin insert holding method to secure SN..54. series negative-rake inserts, providing rigid clamping under interrupted and continuous cuts. Built from steel, this toolholder is intended for installation and use by machinists and CNC turning technicians working in production and job-shop environments.

This toolholder is rated for turning operations across universal workpiece materials, covering material codes H, K, M, N, P, and S — meaning it suits hardened materials, cast iron, stainless steels, non-ferrous metals, steel, and superalloys in a single platform. The Multiple Lock series design provides secure insert indexing without requiring specialized tooling. The back-of-bar to cutting edge dimension is 0.5 inches and the head length is 1.61 inches, keeping the cutting edge well-positioned for standard OD turning passes on both manual and CNC lathes.

Installation Notes

Installation is performed by qualified machinists or CNC turning technicians. Always disengage the spindle and ensure the machine is in a safe, locked-out state before mounting or changing the toolholder. Secure the shank in the tool post or turret to the machine manufacturer's specified clamping torque using appropriate hex or clamping hardware. Verify insert seating and clamp pin engagement before resuming cutting operations.
