Sandvik Coromant 6188564 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 6188564 is a right-hand indexable turning toolholder built to the PVJNR163DHP style, designed for use with VNMG 332 inserts in CNC and manual turning applications. It features a clamp-lever insert holding method that secures the insert with consistent clamping force, maintaining positioning accuracy under heavy facing cuts. The shank measures 1 inch wide by 1 inch tall, and the overall tool length is 6 inches. Constructed from steel, this toolholder is part of the T-Max P series and accommodates negative-rake inserts at a rake angle of -5 degrees. It is suited to machinists and toolroom professionals running facing operations on lathes and turning centers.

This toolholder is intended for facing operations in both production and job-shop turning environments. The 1 inch by 1 inch shank fits standard tool blocks and quick-change toolpost systems common on mid-size lathes. The head length of approximately 1.8 inches positions the cutting edge precisely, with a back-of-bar to cutting edge distance of 6 inches. The multi-use designation means it can be repositioned for varied turning strategies beyond straight facing. Machinists working on steel, cast iron, and similar materials will find the VNMG 332 insert compatibility appropriate for a broad range of general turning tasks.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully in the tool block before torquing the clamping screws to prevent movement during cutting. Always index or replace the insert with the machine powered down and the spindle at a complete stop. Verify insert seating and clamp engagement before resuming any cutting operation.
