Built to the HSER series standard, this right-hand toolholder accepts 16ER inserts secured by a screw clamping method, providing reliable insert retention during threading passes. The shank measures 1.25 x 1.25 inches with an overall length of 7 inches, making it a straightforward drop-in choice for standard square-shank tool blocks. Machinists and CNC operators working on external threaded features will find this holder well-suited to production turning environments where consistent insert indexing is required.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for external threading applications in metalworking operations, typically on CNC turning centers or manual engine lathes equipped with square-shank toolpost systems. The HSER style is a widely recognized toolholder configuration used in both job-shop and production-floor settings. It is installed by qualified machinists or toolroom technicians. No coolant-through capability is present on this unit, so external coolant delivery should be arranged separately when thermal management is needed during threading operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal threading application with right-hand cutting orientation\u003c\/li\u003e\n\u003cli\u003eAccepts 16ER indexable inserts with a 3\/8-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eScrew insert-holding method for secure clamping during threading passes\u003c\/li\u003e\n\u003cli\u003e1.25 x 1.25 inch square shank fits standard square-shank toolpost blocks\u003c\/li\u003e\n\u003cli\u003e7-inch overall length suits common CNC lathe tool block configurations\u003c\/li\u003e\n\u003cli\u003eHSER series style (Style: HSER-1250-7-16) for recognized toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 16ER series indexable threading inserts with a 3\/8-inch inscribed circle.
