Seco 00043252 Sdjc Lh Indexable Turning Toolholder

Product Description

The SECO 00043252 is a left-hand SDJC-style indexable turning toolholder designed for screw-lock insert retention on CNC lathes and turning centers. It features a neutral rake angle of 0 degrees and accepts DC..32.5. series inserts, including the DCMT 32.52. The square shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches and a head length of 1 inch. The back-of-bar to cutting edge distance is 1 inch. Built from steel, this toolholder is suited for high-volume turning operations where repeatable insert positioning and rigid clamping are essential. Licensed machinists and CNC tooling specialists are the primary installers.

This toolholder is intended for external turning applications across a broad range of workpiece materials, including cast iron, non-ferrous metals, stainless steel, heat-resistant alloys, and general steels, corresponding to material codes H, K, M, N, P, and S. The left-hand cutting direction suits right-to-left turning passes or specific machine orientations that require a left-hand tool path. It is appropriate for both production and jobshop environments running standard DCMT-style inserts.

Key Features

• Left-hand cutting direction for right-to-left turning passes
• Neutral rake (0 degrees) geometry for versatile material compatibility
• Screw-lock insert holding method for secure, repeatable clamping
• Accepts DC..32.5. inserts with a 3/8 inch inscribed circle
• Steel construction for rigidity and durability in production turning
• Universal primary workpiece material compatibility across H, K, M, N, P, and S codes

Compatibility

Compatible with DCMT 32.52 inserts and the broader DC..32.5. insert family featuring a 3/8 inch inscribed circle. Designed as a screw-lock SDJC-style toolholder for standard external turning operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state before changing toolholders or inserts. Verify that the insert is fully seated and the clamping screw is properly torqued per the insert manufacturer guidelines before resuming cutting. Confirm tool centerline height and offset values are entered into the machine control after any toolholder change.
