It cuts no chips  -  instead, it cold-forms threads by displacing material, producing stronger threads with a better surface finish than cut taps. The tap is manufactured from powdered metal high-speed steel and carries a TiCN coating for improved wear resistance and lubricity. At 2.375 inches overall length with a 0.4921-inch thread length, it is sized for 10-32 UNF right-hand threads with a bottoming chamfer of 1 to 1.5 thread pitches. Class of fit is 2B, thread limit H5. Machinists and tool-and-die professionals install this tap in drill press, CNC, or tapping arm operations.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The bottoming chamfer geometry allows threading close to the bottom of a blind hole, making it the correct choice when full-depth thread engagement is required in tight bore depths. It is commonly used in precision machining, fixture fabrication, and production tapping operations where thread quality and tool life are critical. The EXOTAP VP-NRT designation indicates OSG formless-tap geometry optimized for ductile and semi-ductile materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal high-speed steel construction provides uniform carbide distribution for extended tool life\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and improves wear resistance across varied workpiece materials\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1 to 1.5P) allows threading to near-bottom depth in blind holes\u003c\/li\u003e\n\u003cli\u003eRight-hand, 10-32 UNF thread form with H5 thread limit for consistent Class 2B fit\u003c\/li\u003e\n\u003cli\u003eCompatible with alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading applications in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces requiring a 10-32 UNF Class 2B thread form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists using a tapping head, CNC machining center, or manual tapping arm  -  ensure the spindle is aligned perpendicular to the workpiece surface before engagement. Secure the workpiece fully before tapping and use an appropriate thread forming lubricant or cutting fluid compatible with the workpiece material. Because this is a forming tap, the correct pilot hole diameter is larger than for a cut tap  -  verify the recommended forming tap drill size for 10-32 UNF before drilling. Do not run this tap in reverse before fully withdrawing from the hole, as reverse rotation can damage formed threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOTAP VP-NRT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4921 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.8660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1940 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1405005808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743955353906,"sku":"1405005808","price":76.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4aae1cb952d37c54dc22a0f15f2f4fcf.jpg?v=1788851905","url":"https:\/\/voomisupply.com\/products\/osg-1405005808-thread-forming-tap-10-32-unf-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
