Seco 02588893 Dcln Indexable Turning Toolholder Cnmg 432

Product Description

The SECO 02588893 is a right-hand DCLN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built around a dual-clamp insert-holding method, it accepts CNMG 432 inserts and delivers a negative 6-degree rake angle for stable, controlled cutting across a wide range of workpiece materials. The shank measures 1.25 inches wide by 1.25 inches tall, with an overall length of 6 inches and a head length of 1.3 inches. Machinists and tool-room technicians rely on this toolholder for high-rigidity roughing and finishing passes where insert security is critical.

This toolholder is suited for use in both production and job-shop turning environments. The DCLN geometry establishes a 95-degree lead angle, making it well matched for straight turning, facing, and shoulder work. The universal primary workpiece material rating covers steel, stainless, cast iron, non-ferrous, and high-temperature alloys, so it transitions readily between material types without requiring a toolholder change. It is a single-use, non-multi-tool holder intended for right-hand cutting direction only.

Key Features

• DCLN toolholder style with dual-clamp insert retention for maximum insert stability under heavy cuts
• Accepts CNMG 432 inserts with a 0.5-inch inscribed circle
• Negative 6-degree rake angle optimized for controlled chip formation and edge strength
• 95-degree lead angle suits straight turning, facing, and light shoulder operations
• 1.25 inch by 1.25 inch square shank fits standard lathe tool blocks and turrets
• Universal workpiece material compatibility covering steel, stainless, cast iron, non-ferrous, and superalloys

Compatibility

Designed for use with CNMG 432 indexable inserts (compatible insert size code CN43). Fits standard square-shank tool blocks and turret stations accepting a 1.25-inch by 1.25-inch shank. Right-hand cutting direction only.

Installation Notes

Installation is typically performed by a machinist or toolroom technician familiar with indexable toolholder setup. Ensure the machine spindle is fully stopped and all stored energy is released before mounting or adjusting the toolholder. Seat the shank fully in the tool block and torque clamping screws per the machine tool manufacturer specifications. Confirm insert seating and clamp screw engagement before resuming cutting operations.
