Seco 00059812 Lh Cfml Indexable Turning Toolholder

Product Description

The SECO 00059812 is a left-hand CFML-style indexable turning toolholder built for cut-off and grooving operations on CNC lathes and turning centers. It features a 1.5-inch by 1.5-inch square shank and an overall length of 7 inches. The clamp-style insert holding method secures LC..1606.. series inserts, including LCGN, LCMF, and LCMR geometries. Built from steel, it supports coolant-through capability for improved chip evacuation and tool life in demanding material removal applications. The 90-degree lead angle and multi-directional turning design make it suitable for a range of turning strategies across universal workpiece materials.

This toolholder is part of the SECO Multi-Directional Turning (MDT) series and is intended for left-hand cutting direction applications. It is suited for use on standard and multi-axis CNC turning equipment where cut-off and grooving operations are performed. The toolholder accommodates universal workpiece materials including steel, stainless, cast iron, non-ferrous alloys, superalloys, and hardened materials, covering material codes H, K, M, N, P, and S. The 2.61-inch head length and 2.0-inch back-of-bar-to-cutting-edge dimension support precise positioning in the tool turret.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician following the machine tool manufacturer's setup procedures. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Verify insert seating and clamp screw engagement before resuming cutting operations. Coolant-through connection should be confirmed compatible with the turret coolant supply port before use.
