Part of the Mini 3 series, this right-hand toolholder features a rectangular shank measuring 0.21 inches in height and 0.25 inches in width, with an overall length of 4 inches and a shank length of 2.98 inches. It accepts 4.0KIR inserts secured by a screw-clamp holding method and includes through-coolant capability for improved chip control and tool life during threading cuts. Machinists and toolroom technicians working with small-bore applications will find this holder well suited to precision threading work.\u003c\/p\u003e\u003cp\u003eThe 66347 is built for internal threading in small-diameter bores, with a minimum bore diameter of 0.24 inches. Its compact Mini 3 series profile makes it appropriate for Swiss-type machines, CNC lathes, and multi-axis turning centers where clearance is limited. The CNVRC toolholder style positions the insert for right-hand cutting, and the head length of 1.02 inches supports a maximum depth of cut of 1.02 inches. Back-of-bar to cutting edge measures 2.54 mm, keeping the cutting edge precisely located within tight bore constraints.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal threading application with right-hand cutting orientation\u003c\/li\u003e\n\u003cli\u003eAccepts 4.0KIR indexable inserts secured by screw-clamp method\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability for chip evacuation and extended insert life\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.24 inches suits small-bore threading work\u003c\/li\u003e\n\u003cli\u003eCNVRC toolholder style in the compact Mini 3 series\u003c\/li\u003e\n\u003cli\u003eOverall length of 4 inches with a shank length of 2.98 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept 4.0KIR series indexable threading inserts.
