Built in the Top Notch series, it accepts N.4R inserts held by a clamp-style insert holding method, providing secure, repeatable seating under heavy cutting loads. The shank measures 1.25 x 1.25 inches with an overall length of 6.0 inches, making it a rigid, full-square shank toolholder suited to demanding production environments. A maximum depth of cut of 0.294 inches gives machinists meaningful material engagement for external thread and grooving work.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for external threading and grooving applications in production machining shops, job shops, and tool rooms running turning centers or manual lathes with appropriate tooling blocks. The Top Notch series design is commonly found in high-volume threading operations where consistent insert indexing and clamping repeatability directly affect thread quality and cycle time. It does not include coolant-through capability, so it is best suited for setups relying on flood or mist coolant delivery from the machine. Machinists and CNC programmers working in metalworking environments are the primary installers and operators of this toolholder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal right-hand thread and grooving toolholder in the Top Notch series\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for secure N.4R insert retention during interrupted cuts\u003c\/li\u003e\n\u003cli\u003eFull-square shank at 1.25 x 1.25 inches for maximum rigidity in the tool block\u003c\/li\u003e\n\u003cli\u003e6.0-inch overall length with a 1.38-inch head length for reach and clearance flexibility\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.294 inches suitable for standard external threading passes\u003c\/li\u003e\n\u003cli\u003eMulti-use design supports both threading and grooving cutting applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with N.4R indexable inserts using a clamp-style holding method.

Power down and lock out the machine spindle before mounting or removing the toolholder. Ensure the tool block mounting surfaces are clean and free of chips before seating the shank, and torque all clamping fasteners to the machine or block manufacturer specifications. Insert indexing and clamping should be verified before returning the machine to production.\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: N.4R\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: 1.25 x 1.25 inches (31.75 x 31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0 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: 1.50 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 2.49 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: 1097593\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728439902514,"sku":"1097593","price":207.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68a30480dacd96d3dad58ca5f6fdac67.jpg?v=1788691193","url":"https:\/\/voomisupply.com\/products\/kennametal-1097593-indexable-threading-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
