Iscar 3800047 Threading Toolholder External Right Hand

Product Description

The ISCAR 3800047 is an indexable threading toolholder designed for external threading operations on metalworking lathes and turning centers. Built in the SER series with a right-hand cutting orientation, this toolholder accepts H 16 inserts secured by a screw-clamp holding method for repeatable positioning under load. The shank measures 0.63 x 0.63 inches square with an overall length of 4.0 inches. It is configured without through-coolant, making it straightforward to mount on standard turrets and tool posts. Machinists and toolroom technicians working in production or job-shop environments will find this a direct-fit solution for threading applications requiring consistent insert indexing.

This toolholder is suited for external threading passes on turned components in both production and maintenance machining environments. The SE toolholder style and H 16 insert compatibility position it for standard unified, metric, and specialty thread profiles depending on the insert grade and geometry selected. The 0.63 x 0.63 inch square shank fits toolpost and turret bores sized for that cross-section. No coolant plumbing is required at the holder, simplifying setup on machines without live coolant at the turret station.
