Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap is configured for 3\/4-10 UNC threads at a 2B class of fit with an H10 thread limit and a modified bottoming chamfer of 2.5 to 3 threads. It is built from cobalt high-speed steel with a TiCN coating, giving it thermal and wear resistance for demanding production and maintenance applications. Licensed machinists and tool and die technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for both blind-hole and through-hole threading operations across a broad material range including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium. The modified bottoming chamfer allows the tap to start threads close to the bottom of a blind hole, making it a practical choice where full thread depth near the hole bottom is required. It is commonly used in CNC machining centers, manual lathes, and tapping heads in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design produces no chips, eliminating chip-jamming risk in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides elevated heat resistance compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life across abrasive and high-strength materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2.5 to 3 thread lead) allows threading close to hole bottom\u003c\/li\u003e\n  \u003cli\u003eH10 thread limit accommodates the dimensional allowance required for thread forming in 2B fit applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, no coolant-through feature, compatible with standard tapping lubricants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium.

Designed for blind-hole and through-hole threading in 3\/4-10 UNC applications requiring a 2B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require a correctly sized forming tap drill hole, which is larger than a standard cut-tap drill size for the same thread — consult the OSG or tool manufacturer forming drill chart for the 3\/4-10 UNC forming hole diameter before drilling. Always apply a compatible tapping fluid or cutting oil rated for the workpiece material, as thread forming generates significant torque and heat. Secure the workpiece fully before tapping and ensure the tap is driven on-axis to avoid thread misalignment or tap breakage. Power down and lock out any CNC or power-feed tapping equipment before changing tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: H10\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\u003eThreads per Inch\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 2.441 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.921 inches (125 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.590 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.6875 inches\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\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-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: 16250 (EXOPRO XPF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.425 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: 1625034100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736286462258,"sku":"1625034100","price":444.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_d3db2d6a-65a9-4824-b884-61d20360a7d9.jpg?v=1788777009","url":"https:\/\/voomisupply.com\/products\/osg-1625034100-thread-forming-tap-3-4-10-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
