Hertel 1000162 Lh Mtfn Indexable Turning Toolholder

Product Description

The HERTEL 1000162 is a left-hand MTFN-style indexable turning toolholder designed for use with TN..54. series inserts in metal-cutting lathe operations. Built from steel, it features a 1.5-inch by 1.5-inch square shank and an overall length of 6 inches. The holder applies a negative rake angle of -5 degrees, which delivers increased cutting edge strength and is well suited for interrupted cuts and harder workpiece materials. Insert retention is achieved through a clamp and screw holding method, providing rigid, repeatable positioning at the cutting edge. This toolholder is intended for installation by machinists and toolroom professionals on manual or CNC turning centers.

The 1000162 is appropriate for external turning operations on lathes where a left-hand tool approach is required. Its MTFN style positions the insert for straight turning and facing with the cutting edge offset 2 inches back from the bar. The 5/8-inch inscribed circle insert seat accommodates TN..543 compatible inserts. It is a single-application toolholder with no coolant-through capability and is part of the Multi-Option series, making it a straightforward drop-in for standard square-shank toolpost setups.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the turning center before changing or seating the toolholder. Ensure the toolpost or turret pocket is clean and free of chips before mounting to maintain accurate tool height and centerline alignment. Follow the machine manufacturer torque guidance for toolpost clamping hardware and verify insert seating before resuming cuts.
