Seco 00086333 Grooving Cutoff Toolholder Left Hand

Product Description

The SECO 00086333 is an indexable grooving and cutoff toolholder designed for external turning operations on CNC lathes and turning centers. Built to the CFTL style in a left-hand orientation, it accepts LC..1603.. series inserts secured by a clamp-style holding method for repeatable edge positioning. The shank measures 1 inch by 1 inch with an overall length of 6 inches, fitting standard square-shank tooling blocks. Maximum depth of cut is 0.43 inches with a minimum groove width of 3 mm (0.118 inches), making it suited for precision grooving and parting applications across a range of workpiece materials.

This toolholder is intended for external grooving and cutoff work in production and job-shop turning environments. It is typically installed by machinists and CNC setup technicians on turret-style lathes and live-tool turning centers. The CFTL style and MDT series designation indicate compatibility with Multi-Directional Turning operations, allowing radial, axial, and face grooving approaches depending on the insert selected. No coolant-through capability is present in this holder, so external coolant delivery should be configured at the machine or turret level when required.

Verify insert seating and clamp engagement before resuming operation. Follow applicable shop safety procedures and machine tool manufacturer guidelines when setting tool offsets and depth-of-cut parameters.
