Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap is manufactured from cobalt high speed steel with a V-coating finish, making it well suited for demanding production and maintenance applications. It has an overall length of 90 millimeters and a thread length of 12 millimeters, with a tapping depth of 35 millimeters. The D9 thread limit designation ensures dimensional accuracy for standard 6H tolerance threads. Licensed machinists, toolmakers, and maintenance professionals are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is engineered for blind hole threading operations across a wide range of materials. Its cobalt construction and V-coating support use in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium. The bottoming chamfer with 1.5 to 2 threads of lead allows threading close to the bottom of a blind hole, which is critical in tight-tolerance machining scenarios. It belongs to the OSG EXOPRO XPF Series 16350 product line.\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 extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1.5-2P) allows threading to near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e6H class of fit with D9 thread limit ensures dimensional compliance for standard metric tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, M8x1.25 metric pitch\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement, compatible with standard tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for M8x1.25 metric blind hole threading applications in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium workpieces.

Ensure proper lubrication or tapping fluid is applied, as thread forming generates higher torque than cutting taps, particularly in harder alloys. Power down or disengage the spindle before manually reversing or removing the tap from a blind hole. Follow applicable shop safety protocols and machine tool manufacturer guidelines for tapping speed and torque settings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 90 millimeters (3.543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 12 millimeters (0.472 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 35 millimeters (1.378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.08 millimeters (0.318 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 6.05 millimeters (0.238 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 9.53 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16350 (EXOPRO XPF)\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.073 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: 1635081219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738282524978,"sku":"1635081219","price":130.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3299a5522130241ca27ef656891389e6_11e289a0-b88f-443d-b6a7-e66dc8e8a8a7.jpg?v=1788797643","url":"https:\/\/voomisupply.com\/products\/osg-1635081219-thread-forming-tap-m8x1-25-metric-6h","provider":"Voomi Supply","version":"1.0","type":"link"}
