Hertel 1002864 Lh Mtjn Negative Rake Indexable Toolholder

Product Description

The HERTEL 1002864 is a left-hand MTJN-style indexable turning toolholder designed for negative rake cutting applications on the lathe. It accepts TN..432 series inserts and features a square shank measuring 1 inch wide by 1 inch tall with an overall length of 6 inches. The toolholder is part of the Multi-Option series, making it a versatile choice for a range of turning operations. Machinists and toolroom professionals install this holder in CNC and manual turning centers where consistent, repeatable insert positioning is required for facing, profiling, and straight turning work.

This toolholder is suited for use in production and job-shop environments where left-hand turning operations are performed. The negative rake geometry reduces cutting forces transmitted to the insert, which is advantageous when machining harder materials or when rigidity is a priority. The 1 inch by 1 inch shank fits standard toolpost and quick-change toolholder systems common in mid-size turning centers. It is sold individually with a minimum order quantity of one unit.
