With a 22mm minimum bore diameter, a 16mm shank diameter, and a 90mm overall length, this bar is built for tight-bore applications where rigidity and repeatability matter. It accepts TPGX 73.. series triangular inserts secured by screw clamping, and features through-coolant capability to manage chip evacuation and heat at the cutting zone. Licensed machinists and CNC operators working in production or job-shop environments will find this bar suited to close-tolerance internal diameter work.\u003c\/p\u003e\n\u003cp\u003eThe 4550303 is intended for boring operations where bore diameters range from 22mm up to 30mm, with a maximum bore depth of 60mm. Its IHAXF toolholder style and ISO 13399 compliance make it compatible with standard tooling management systems. This bar is a fit for both roughing and finishing passes in small-bore internal turning where through-coolant delivery improves tool life and surface finish. It is part of the Itsbore series, which targets compact, high-precision boring applications in metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIHAXF toolholder style with screw-clamp insert holding for secure, repeatable edge positioning\u003c\/li\u003e\n  \u003cli\u003eAccepts TPGX 73.. triangular inserts for versatile grade and geometry selection\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs fluid directly to the cutting zone for improved chip control and tool life\u003c\/li\u003e\n  \u003cli\u003eBore range of 22mm to 30mm with a maximum depth of 60mm suits small-bore production work\u003c\/li\u003e\n  \u003cli\u003eISO 13399 compliant for integration with digital tooling data and presetter systems\u003c\/li\u003e\n  \u003cli\u003e16mm shank diameter fits standard boring bar holders and quick-change tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TPGX 73.. series triangular inserts, insert size code 73, secured via screw clamping.

Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the boring bar. Verify shank clamping torque against the machine tool manufacturer specifications for 16mm boring bars. Confirm through-coolant passages are clear and the coolant supply line is properly connected before running the first part.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 22mm (0.8661 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 30mm (1.1811 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 60mm (2.3622 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16mm (0.6299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 90mm (3.5433 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: IHAXF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TPGX 73..\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 73\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Itsbore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4550303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":67609184403762,"sku":"4550303","price":292.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6116f9c459093a2fdebdd9856b277617.jpg?v=1790432221","url":"https:\/\/voomisupply.com\/products\/iscar-4550303-indexable-boring-bar-22mm-bore-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
