The tool features a 25mm shank diameter, a 200mm overall length, and a minimum bore diameter of 20mm, making it suitable for tight-bore applications where rigidity and reach must be balanced. Inserts are retained by a screw-clamp holding method, ensuring repeatable positioning under interrupted cuts and heavy feeds. Through-coolant capability directs fluid directly to the cutting zone for improved chip evacuation and tool life.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for use in production turning environments where grooving and recessing operations are performed in bores starting at 20mm. It accepts DGN, GRIP, and HFPR insert styles, giving machinists flexibility across grooving widths and profiles. The right-hand cutting direction suits standard spindle rotation on conventional CNC turning setups. Applications include internal groove cutting, face grooving, and parting in a range of workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMinimum bore diameter of 20mm (0.7874 inches) for tight-clearance internal operations\u003c\/li\u003e\n  \u003cli\u003eCompatible with DGN, GRIP, and HFPR insert styles for versatile grooving and parting profiles\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design for direct chip evacuation and cutting-zone temperature control\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert retention for consistent repeatability and positive insert seating\u003c\/li\u003e\n  \u003cli\u003e200mm (7.874 inches) overall length with 25mm (0.9843 inches) shank diameter\u003c\/li\u003e\n  \u003cli\u003eMulti-use capability across grooving, recessing, and turning in a single toolholder\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for CAM and tool management integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with DGN, GRIP, and HFPR series inserts.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or changing the toolholder. Confirm shank bore diameter and coolant-through port alignment in the turret before securing. Follow the machine tool manufacturer torque specifications for the toolholder clamping fasteners, and verify insert seating and screw torque per the insert manufacturer guidelines before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 20mm (0.7874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25mm (0.9843 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 200mm (7.874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 11.14mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HFI-MC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Heliface\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DGN, GRIP, HFPR\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\u003eCutting Tool Application\u003c\/strong\u003e: Grooving, Parting, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Grooving, Recessing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 2500337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51733672821042,"sku":"2500337","price":496.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82f9e614e9068ae5fc559c2c7671ea52.jpg?v=1788757886","url":"https:\/\/voomisupply.com\/products\/iscar-2500337-hfi-mc-indexable-boring-bar-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
