Manufactured in the NT4R style and graded KC730, it carries a Titanium Nitride (TiN) finish applied via PVD coating process. The insert cuts a partial profile 60-degree thread form and handles both internal and external threading operations. With an included angle of 60 degrees and a corner radius of 0.17 mm (0.0067 inches), it delivers consistent thread geometry across a broad pitch range. Machinists and toolroom operators working with steel and cast iron applications install this insert into compatible Top Notch series toolholders.\u003c\/p\u003e\u003cp\u003eThis insert covers external pitch ranges of 1.25 to 6.25 mm (4 to 20 TPI) and internal pitch ranges of 2.00 to 6.25 mm (4 to 12 TPI), making it suited for a wide variety of threading tasks in production and job shop environments. It is appropriate for both roughing and finishing thread passes on ferrous materials classified under material grades C2, C3, and C4. Right-hand cutting geometry makes it the standard choice for conventional thread direction on turned components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride (TiN) coating for wear resistance on ferrous materials\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form cuts both internal and external threads\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 1.25 to 6.25 mm (4 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003eInternal pitch range: 2.00 to 6.25 mm (4 to 12 TPI)\u003c\/li\u003e\n\u003cli\u003eRight-hand insert geometry for standard thread direction\u003c\/li\u003e\n\u003cli\u003eTop Notch series insert size 4 for direct drop-in fit to compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series threading toolholders that accept NT insert style, size 4.

Use the appropriate torque wrench and insert clamp screw specified for the Top Notch toolholder to seat the insert securely without over-torquing the clamping mechanism. Inspect the insert pocket for chips or debris before seating the new insert, as contamination can cause improper seating and thread form deviation. Replace the insert at first sign of chipping, edge wear, or degraded surface finish on threaded workpieces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NT4R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Partial Profile 60 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 1.25 to 6.25 mm (4 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 2.00 to 6.25 mm (4 to 12 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.17 mm (0.0067 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 3.25 mm (0.1280 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 6.48 mm (0.2551 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: 0.0448 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: 1112953\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743944638770,"sku":"1112953","price":242.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/576a148a5bd7b90117eec0b9951029d5.jpg?v=1788851710","url":"https:\/\/voomisupply.com\/products\/kennametal-1112953-threading-insert-nt4r-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
