It accepts N151.2-200-5E inserts held by a clamp-style retention method, delivering consistent edge positioning for external grooving and parting operations on CNC lathes and turning centers. The shank measures 0.5 inches in height and 0.5 inches in width, with an overall length of 5.91 inches. Maximum depth of cut reaches 15.01 mm (0.591 inches), and the toolholder accommodates groove widths from 1.85 mm to 2.39 mm (0.0728 to 0.239 inches nominal range). Machinists and CNC setup technicians install this holder in standard square-shank tool posts or turret blocks.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external grooving, recessing, and cutoff operations on turning centers and engine lathes. The T-Max Q-Cut series is designed for stable, repeatable insert seating in production environments where consistent groove geometry and part-off accuracy are critical. The right-hand orientation means cutting engagement occurs from right to left relative to the spindle face. Compatible insert seat size is 20.0. No coolant-through capability is present in this configuration, so external coolant delivery should be directed at the cutting zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClamp-style insert retention for rigid, repeatable seating of N151.2-200-5E inserts\u003c\/li\u003e\n\u003cli\u003eGroove width range of 1.85 mm to 2.39 mm for precise external grooving and parting\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 15.01 mm (0.591 inches) supports deep groove and cutoff applications\u003c\/li\u003e\n\u003cli\u003eSquare shank at 0.5 x 0.5 inches fits standard turret and tool-post blocks\u003c\/li\u003e\n\u003cli\u003eOverall length of 5.91 inches with shank length of 5.28 inches for standard reach requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for conventional lathe and turning center setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with N151.2-200-5E inserts at insert seat size 20.0, as part of the SANDVIK COROMANT T-Max Q-Cut series, catalog style R\/L151.20.

Power down and lock out the machine spindle before changing or seating the toolholder. Secure the shank fully within the turret or tool-post block to the depth recommended by the machine tool manufacturer, ensuring no excessive overhang beyond what the application requires. Verify insert seating and clamp engagement before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number\u003c\/strong\u003e: R151.20-08-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max Q-Cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: R\/L151.20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert\u003c\/strong\u003e: N151.2-200-5E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 20.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Groove Width\u003c\/strong\u003e: 1.85 mm (0.0728 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Groove Width\u003c\/strong\u003e: 2.39 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 15.01 mm (0.591 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 12.70 mm (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 12.70 mm (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 134.11 mm (5.28 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 150.11 mm (5.91 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 12.70 mm (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 12.70 mm (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal or External\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5742260\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51733279605042,"sku":"5742260","price":278.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f821a972f44e8309951faf558585fde_f1bc571d-eb28-46f9-848a-fac871e98f8b.jpg?v=1788753511","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5742260-grooving-toolholder-r151-20-08-20","provider":"Voomi Supply","version":"1.0","type":"link"}
