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 and features a bottoming chamfer of 1.5 to 2 threads, allowing threading close to the bottom of a blind bore. The EXOPRO XPF-OIL series design includes coolant-through capability, making it suitable for CNC tapping centers and automated production environments. Overall length is 3.54 inches (90 mm) with a tapping depth of 1.38 inches (35 mm).\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading a wide range of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium. The bottoming chamfer makes it the correct choice when thread engagement must start close to the blind hole floor. It is commonly used in precision machining, toolroom work, and production tapping where a strong, chip-free thread form is required. Installation is performed by machinists and toolroom technicians using CNC machining centers or manual tapping equipment.\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 issues in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt high speed steel construction with V-coating for extended tool life in tough materials\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (1.5 to 2P) allows threading to within a minimal distance of the blind hole floor\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability supports high-speed CNC tapping with internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003eD9 thread limit maintains 6H class of fit tolerance for metric fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, M8x1.25 pitch, series 16150 EXOPRO XPF-OIL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in aluminum, cast aluminum, hardened steel, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium workpieces.

Ensure the workpiece is securely fixtured and the tapping axis is aligned to avoid tap breakage. Use appropriate tapping fluid or engage the coolant-through feature when running in CNC equipment. Inspect the tap for wear or deformation before each use, particularly when working in hardened or high-nickel alloy materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1.25\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: D9\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: 1.5 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\u003eOverall Length\u003c\/strong\u003e: 3.54 inches (90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.47 inches (12 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.38 inches (35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches (8.08 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches (6.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 9.53 mm\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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\u003eSeries\u003c\/strong\u003e: 16150 EXOPRO XPF-OIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.068 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: 1615081219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747303883058,"sku":"1615081219","price":142.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3299a5522130241ca27ef656891389e6_ab5a521d-1214-4117-b201-0aed06f18d1c.jpg?v=1788878718","url":"https:\/\/voomisupply.com\/products\/osg-1615081219-thread-forming-tap-m8x1-25-metric-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
