Seco 00013341 Sdjc Indexable Turning Toolholder

Product Description

The SECO 00013341 is a right-hand SDJC-style indexable turning toolholder designed for screw-lock insert retention with a neutral rake angle of 0 degrees. The toolholder features a 0.5 inch by 0.5 inch steel shank and an overall length of 3.5 inches, making it a compact and rigid option for general turning operations. It accepts DC..21.5. series inserts with a 0.25 inch inscribed circle, secured via a screw-lock clamping method. Licensed machinists and tooling technicians install this holder on CNC lathes and manual turning centers where controlled insert positioning and repeatability are required.

This toolholder is suited for external turning applications across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, and superalloys, as indicated by its universal primary workpiece material rating spanning H, K, M, N, P, and S material groups. The 3-degree lead angle geometry and right-hand cutting direction make it a practical selection for straight turning and facing passes in production and job-shop environments. The screw-lock Series design provides positive insert seating and consistent edge repeatability across insert changes.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on a powered-down lathe or turning center with the spindle locked and all motion axes disabled. Confirm insert seating and screw torque per the insert manufacturer's clamping specifications before resuming operation. Inspect the shank bore and toolholder pocket for chips or debris before mounting to ensure proper seating and avoid shank damage. Follow facility and machine tool manufacturer guidelines for tool offset measurement and verification after each insert change.
