Built from Vanadium High Speed Steel (HSS-E) with a steam oxide coating, this tap offers improved lubricity and corrosion resistance during threading operations. The plug chamfer distributes cutting load across the first few threads, making it well suited for through-hole tapping. With a 3-flute geometry and spiral point design, chips are pushed forward ahead of the cutting edge rather than packing in the flute, reducing the risk of tap breakage in production environments. Overall length is 4.921 inches with a thread length of 1.21 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, maintenance, and manufacturing environments for tapping through holes in aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and hardened steel. It is appropriate for CNC machining centers, drill presses, and tapping machines where through-hole threading at 3\/4-10 UNC is required. The H2 thread limit designation indicates a tight tolerance class suitable for 2B class of fit threads. Licensed machinists and tool-and-die technicians are the primary users of this tap in both job shop and production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, keeping flutes clear during through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eVanadium HSS-E construction provides increased wear resistance and toughness over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves lubricity and reduces built-up edge on the cutting faces\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting forces across multiple threads for smooth entry\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit holds tight tolerances for 2B class of fit applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement — compatible with flood, mist, or paste lubricant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole tapping at 3\/4-10 UNC in aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and hardened steel.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the threading operation. Apply a suitable cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Inspect the tap for chips or wear before each use and replace if cutting edges show visible damage.\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (HSS-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\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\u003eThread Length\u003c\/strong\u003e: 1.21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.381 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: 2533601\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733149614386,"sku":"2533601","price":146.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aea37d07fd000d7baee2f06f27849f91_15b83177-2c3c-4386-b3cc-368301794de9.jpg?v=1788751944","url":"https:\/\/voomisupply.com\/products\/osg-2533601-spiral-point-tap-3-4-10-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
