Built from Vanadium High Speed Steel (HSS-E) with a Titanium Nitride (TiN) coating, it delivers extended tool life and reduced friction compared to uncoated alternatives. The spiral point geometry pushes chips ahead of the cutting action, keeping flutes clear and allowing higher feed rates in production environments. With a 10-24 UNC thread form, H3 thread limit, and 2B\/3B class of fit, this tap meets standard fastener tolerance requirements for general mechanical assembly. It is suited for use in CNC machining centers, drill presses, and tapping heads where consistent thread quality is required.\u003c\/p\u003e\u003cp\u003eThis tap is intended for right-hand threading of through-hole applications in materials including aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, hardened steel, and cast iron. The TiN coating makes it particularly effective in production runs where abrasive materials accelerate wear on uncoated tooling. The 10-24 UNC size is commonly used in light mechanical assemblies, electronics enclosures, and sheet metal fabrication requiring machine-cut internal threads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-24 UNC thread form with H3 thread limit and 2B\/3B class of fit\u003c\/li\u003e\n\u003cli\u003eVanadium High Speed Steel (HSS-E) construction for toughness in interrupted and difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and improves wear resistance in high-cycle production use\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e3 flutes with plug chamfer for easy thread start and balanced cutting forces\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard spiral point plug tap for through-hole machine tapping in materials including aluminum, stainless steel, alloy steel, die steel, cast iron, and low-, medium-, and high-carbon steel.

Ensure the tap is properly aligned with the drilled pilot hole before engaging the spindle to avoid thread damage or tool breakage. Use the appropriate cutting fluid or coolant for the material being tapped to maintain tool life. Power down and secure the machine before changing or inspecting the tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24 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\/3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.492 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 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\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 1740405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728058188082,"sku":"1740405","price":44.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b769289ca2a7d9e0b0defbb95fa207db.jpg?v=1788687208","url":"https:\/\/voomisupply.com\/products\/osg-1740405-spiral-point-tap-10-24-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
