Seco 00013340 Msdn Neutral Indexable Turning Toolholder

Product Description

The SECO 00013340 is an MSDN-style neutral-hand indexable turning toolholder designed for external turning operations on CNC and manual lathes. Built from steel with a 0.75 inch square shank (0.75 inch wide by 0.75 inch high) and an overall length of 4.5 inches, this toolholder accepts SN..43. series inserts secured by a clamp and pin holding method. The negative rake geometry (rake angle: -6 degrees, 0 degrees) suits harder workpiece materials and interrupted cuts. It is typically installed by machinists and CNC operators in production and job-shop turning environments.

This toolholder is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S — spanning steels, cast irons, stainless, non-ferrous alloys, superalloys, and general-purpose materials. The neutral cutting direction makes it appropriate for both right-hand and left-hand setups at the same station, reducing the need for dedicated left- or right-hand holders in mixed-production environments. The Multiple Lock series design provides rigid insert clamping under high cutting loads common in roughing and semi-finishing passes.

• Accepts SN..43. (compatible insert size code SN43) inserts with 0.5 inch inscribed circle
• Clamp and pin insert holding method for secure seating under interrupted or heavy cuts
• Negative rake geometry for strength and edge durability on hard or abrasive materials
• Steel construction with 0.75 x 0.75 inch shank fits standard toolpost and turret pockets
• Universal material compatibility across ISO material groups H, K, M, N, P, and S

Compatibility

Designed to accept SN..43. series inserts with a compatible insert size code of SN43 and a 0.5 inch inscribed circle. Catalog reference number MSDNN124. Intended for use in turning applications across universal workpiece material groups.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Power down and lock out the machine before mounting or changing the toolholder or insert. Ensure the shank pocket and clamping surfaces are clean and free of chips before seating the holder. Verify insert orientation and clamping torque per the machine tool manufacturer's specifications before resuming operation.
