Unlike cutting taps, thread forming taps cold-form threads by displacing material rather than cutting it, producing stronger threads with no chips. This tap features a cobalt substrate with a TiCN (Titanium Carbonitride) coating and a modified bottoming chamfer of 2.5 to 3 threads, making it well suited for threading close to the bottom of blind holes. It carries a 6H class of fit and D12 thread limit. Part of the OSG EXOPRO XPF Series 16350, it is installed by machinists, toolmakers, and skilled trades professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in a wide range of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium. It is suited for both blind hole and through-hole threading operations. With an overall length of 5.51 inches (140 mm) and a thread length of 0.98 inches (25 mm), it fits standard tapping setups on CNC machining centers and manual tap handles designed for M20 shank diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life across a broad material range\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2.5 to 3 threads) allows threading closer to hole bottoms\u003c\/li\u003e\n  \u003cli\u003e6H class of fit and D12 thread limit for controlled tolerance output\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; compatible with both blind and through-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for M20x2.50 metric coarse thread forming in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium.

Use a tapping fluid or cutting oil appropriate for the workpiece material. Ensure the spindle is aligned perpendicular to the workpiece before engagement. Power down or de-energize the machine and secure the workpiece before changing or inspecting tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20x2.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\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: D12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2.5 to 3 threads\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.51 inches (140 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.98 inches (25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 2.43 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\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: Aluminum, Cast Aluminum, Hardened Steel, Carbon Steel, Alloy Steel, Die Steel, Stainless Steel, High-Nickel Alloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16350\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Name\u003c\/strong\u003e: EXOPRO XPF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.542 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1635020252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730935415090,"sku":"1635020252","price":425.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_78bc6959-37e2-4745-bf49-33c5b53e0152.jpg?v=1788725014","url":"https:\/\/voomisupply.com\/products\/osg-1635020252-thread-forming-tap-m20x2-50-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
