Seco 00013345 Msdn Neutral Indexable Turning Toolholder

Product Description

The SECO 00013345 is a neutral-hand MSDN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built on a 1 inch x 1 inch square shank and measuring 6 inches in overall length, this toolholder accepts SN..43. series inserts secured by a clamp and pin Multiple Lock holding method. The negative rake geometry at -6 degrees suits heavy interrupted cuts and hard materials where edge strength is critical. The steel body provides rigidity for consistent insert seating across extended production runs. Licensed machinists and CNC setup technicians are the primary installers.

This toolholder is suited for universal turning applications across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and aluminum, corresponding to ISO material codes H, K, M, N, P, and S. The neutral cutting direction makes it interchangeable in both left-hand and right-hand setups, reducing tooling inventory requirements in multi-operation turning environments. It is well suited for both production and job-shop turning where a single toolholder must cover varied material grades.

Key Features

• MSDN toolholder style with neutral hand for flexible left- or right-side turning setups
• Clamp and Pin Multiple Lock insert holding method for secure, repeatable insert positioning
• Accepts SN..43. inserts with a 0.5 inch inscribed circle
• Negative rake angle of -6 degrees provides enhanced cutting edge strength on demanding materials
• 1 inch x 1 inch steel shank with 6 inch overall length and 1.39 inch head length
• Back of bar to cutting edge dimension of 0.5 inches for consistent tool center height setup
• No coolant-through — external coolant application only

Compatibility

Designed to accept SN..43. series indexable inserts with a compatible insert size code of SN43 and a 0.5 inch inscribed circle. Suitable for universal turning applications across ISO workpiece material groups H, K, M, N, P, and S.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before changing inserts or mounting the toolholder, confirm the machine spindle is stopped and the control is in a safe state per the machine tool manufacturer procedures. Secure the shank in the tool block or turret to the torque specification listed in the machine tool documentation — do not rely on feel alone. Verify tool center height against the spindle centerline before taking a first cut.
