Built on a 1 inch x 1 inch square shank with an overall length of 6 inches, this toolholder uses a clamp-and-pin Multiple Lock holding method to secure TN..43. series inserts. The negative rake geometry at -5 degrees provides controlled cutting action suited to interrupted cuts and harder workpiece materials. It is installed and set up by machinists and CNC operators working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is designed for right-hand cutting direction and accepts inserts with a 1\/2 inch inscribed circle. It is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S — meaning it handles a broad range of metals from carbon steels and stainless steels to cast irons, nonferrous alloys, and high-temperature alloys. The -3 degree lead angle and 1.19 inch head length position the insert at the correct approach for straight turning and facing passes, with the back-of-bar to cutting edge dimension set at 1.25 inches for proper tool centerline alignment at standard tool post heights.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMTJN-style toolholder with Multiple Lock clamp-and-pin insert retention for positive insert seating under interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle of -5 degrees improves edge strength and is well-suited for tough, hard, or abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e1 inch x 1 inch square shank fits standard tool post blocks and turret stations sized for 1 inch tooling\u003c\/li\u003e\n  \u003cli\u003eCompatible with TN..43. series inserts with a 1\/2 inch inscribed circle, offering broad grade and geometry availability from multiple insert suppliers\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility across ISO material groups H, K, M, N, P, and S\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder body provides rigidity and resistance to deflection during heavy roughing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept TN..43. series indexable inserts with a compatible insert size code of TN43 and a 1\/2 inch inscribed circle.

Before mounting or changing inserts, de-energize and lock out the machine spindle per facility lockout\/tagout procedures. Secure the shank fully in the turret pocket or tool post, ensuring the cutting edge is set to the correct centerline height before tightening clamping hardware. Inspect the insert seat and clamp components for chips or debris before seating a new insert, as contamination in the pocket can affect insert security and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MTJN\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\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TN..43.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: TN43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multiple Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00014440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564287230258,"sku":"00014440","price":177.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bad193e4ff2cfe4028707f735477c8a5.jpg?v=1786516389","url":"https:\/\/voomisupply.com\/products\/seco-00014440-mtjn-indexable-turning-toolholder-1-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
