Seco 00071945 Lh Sclc Indexable Turning Toolholder 0.5 in Shank

Product Description

The SECO 00071945 is a left-hand SCLC-style indexable turning toolholder designed for use on CNC and manual lathes in metal-cutting operations. It features a neutral rake angle of 0 degrees and a -5 degree lead angle, providing stable cutting geometry across a wide range of workpiece materials. The 0.5 inch by 0.5 inch square shank and overall length of 3.5 inches make it a compact, rigid platform for precision turning. Insert retention is handled by a screw-lock clamping method, which delivers consistent seating and repeatability during high-cycle production work. Licensed machinists and CNC operators typically install and index this holder.

This toolholder is suited for external turning applications in both job shop and production environments. The universal primary workpiece material rating covers steels, stainless steels, cast irons, non-ferrous metals, superalloys, and other common turned materials. The screw-lock series design is a standard configuration recognized across manual and CNC turning centers. It accepts CC..32.5. series inserts, including CCMT 32.52 geometries, and the inscribed circle of the compatible insert is 0.375 inches. The back-of-bar to cutting edge dimension is 0.625 inches, which is relevant when setting tool height relative to centerline.

Key Features

• Left-hand cutting direction for right-to-left turning passes
• Neutral rake angle (0 degrees) for broad material compatibility
• Screw-lock insert retention for repeatable indexing and positive clamping
• Accepts CCMT 32.52 and compatible CC..32.5. series inserts
• 0.5 inch x 0.5 inch square steel shank fits standard tool posts and turrets
• No coolant-through design — standard external coolant delivery applies

Compatibility

Designed for use with CC..32.5. series inserts, including CCMT 32.52 geometry inserts with a 0.375 inch inscribed circle. Compatible workpiece material codes include H, K, M, N, P, and S, covering a universal range of turned materials. Fits tool posts and turrets accepting a 0.5 inch square shank.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Before changing inserts or mounting the toolholder, power down the machine and ensure the spindle is fully stopped. Set tool height to spindle centerline using a dial indicator or height gauge before taking a first cut. Follow the machine tool manufacturer's torque guidance for insert screw tightening, and inspect the insert seat and clamping screw for debris before seating a new insert.
