Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap is built from cobalt high speed steel with a V-coating finish and features a bottoming chamfer for threading close to the bottom of a blind hole. With an overall length of 4.921 inches and a thread length of 0.984 inches, it is engineered for precision metric threading in demanding production and maintenance environments. It is installed by licensed machinists, toolmakers, and maintenance technicians working with CNC or manual tapping equipment.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading in a wide range of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, hardened steel, high-nickel alloy, and titanium. The bottoming chamfer style with 1.5 to 2 chamfered threads allows the tap to begin forming threads very close to the bottom of a blind hole. Coolant-through capability supports high-speed tapping operations where internal coolant delivery is available. The D11 thread limit and 6H class of fit ensure consistent thread tolerance compliance in metric applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material for chip-free, stronger threads in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt high speed steel construction with V-coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 1.5 to 2 chamfered threads for threading near blind hole bottom\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed and automated tapping operations\u003c\/li\u003e\n\u003cli\u003eD11 thread limit with 6H class of fit for consistent metric thread tolerance\u003c\/li\u003e\n\u003cli\u003eCompatible with a broad range of ferrous and non-ferrous materials including titanium and high-nickel alloy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for M20x1.50 metric blind hole threading applications across aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, hardened steel, high-nickel alloy, and titanium workpieces.

Power down and lock out all machine tools before changing or inspecting tooling. Thread forming taps require adequate lubrication or coolant flow — verify the machine spindle supports coolant-through delivery when using this tap at production speeds. Follow the machine tool manufacturer guidelines and applicable shop safety standards when setting tapping depth to avoid bottoming out the tap against the hole floor.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20x1.50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1.5 to 2P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: Cobalt High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: V-Coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.921 inches (125.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.984 inches (25.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 2.433 inches (61.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.652 inches (16.56 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.489 inches (12.42 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 17.46 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Name\u003c\/strong\u003e: EXOPRO XPF-OIL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Hardened Steel, Carbon Steel, Alloy Steel, Die Steel, Stainless Steel, High-Nickel Alloy, Titanium\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: 1615020111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732175388978,"sku":"1615020111","price":480.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3299a5522130241ca27ef656891389e6_930baf9f-0716-4bc5-9d8a-8441c500f4a2.jpg?v=1788740062","url":"https:\/\/voomisupply.com\/products\/osg-1615020111-thread-forming-tap-m20x1-50-metric-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
