Part of the Top Notch series, it features a 1 x 1 inch square shank and an overall length of 6 inches, making it a compact and rigid platform for insert-based cutting work. The NS-style toolholder accepts N.4L inserts secured by a clamp-style holding method, delivering consistent insert positioning and reliable cutting performance across threading and grooving applications. Designed for professional machinists and toolroom technicians, this holder is suited for high-repetition production turning environments where insert changeability and runout consistency matter.\u003c\/p\u003e\u003cp\u003eThis toolholder is used in external threading and grooving operations on CNC lathes and manual turning centers. The left-hand orientation makes it the correct choice for right-to-left cutting passes or setups where workpiece geometry or turret configuration requires it. With a maximum depth of cut of 0.294 inches and a head length of 1.38 inches, it handles a practical range of thread profiles and groove depths. The back-of-bar to cutting edge dimension is 1.25 inches, and the center to cutting edge measurement is 0.54 inches, supporting accurate tool offset entry during setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand external thread and groove cutting orientation\u003c\/li\u003e\n\u003cli\u003eNS-style holder accepts N.4L indexable inserts with clamp retention\u003c\/li\u003e\n\u003cli\u003e1 x 1 inch square shank for rigid, repeatable seating in standard tool blocks\u003c\/li\u003e\n\u003cli\u003e6-inch overall length keeps overhang minimal and chatter resistance high\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.294 inches suitable for a broad range of threading profiles\u003c\/li\u003e\n\u003cli\u003eMulti-use design supports both threading and grooving without toolholder change\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with N.4L series Top Notch indexable inserts.

Ensure the lathe or turning center is fully powered down and the spindle is locked before seating or removing the toolholder. Secure the shank in a qualified tool block or turret station rated for the 1 x 1 inch shank cross-section, following the machine tool manufacturer torque guidelines for clamping fasteners. Verify tool offset values in the CNC control after installation before initiating a cutting pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: NS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: N.4L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width and Height\u003c\/strong\u003e: 1 inch x 1 inch (25.40 mm x 25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.38 inches (35.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.294 inches (7.47 mm)\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\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.54 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving and Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5975 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1097266\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51751945470258,"sku":"1097266","price":208.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/478956cee0265f7880d7b27b831df3cc.jpg?v=1788924806","url":"https:\/\/voomisupply.com\/products\/kennametal-1097266-indexable-threading-toolholder-1x1","provider":"Voomi Supply","version":"1.0","type":"link"}
