Built from powdered metal and coated with TiCN (titanium carbonitride), it delivers increased surface hardness and lubricity compared to standard HSS taps, making it a solid choice for production environments where tool life matters. The plug chamfer distributes the cutting load across several leading threads, easing entry into pre-drilled holes. It cuts a 3\/8-16 thread to a 2B class of fit with an H5 thread limit, providing the tolerance control required for standard fastener applications in machined assemblies.\u003c\/p\u003e\u003cp\u003eThis tap is suited for use in CNC machining centers, knee mills, and drill presses where through-hole tapping is performed on workpiece materials including alloy steel, low-carbon steel, medium-carbon steel, high-carbon steel, stainless steel, cast iron, die steel, aluminum, cast aluminum, and hardened steel. The right-hand, three-flute spiral point design pushes chips forward ahead of the tap, keeping the flutes clear and reducing the risk of chip packing in through-hole applications. It is part of the OSG EXOTAP VC-10 series 16535.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces friction for extended tool life in steel and stainless applications\u003c\/li\u003e\n\u003cli\u003ePowdered metal substrate provides a finer grain structure and greater toughness than conventional HSS\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (approximately 3-5 thread lead) eases starting and distributes cutting forces across entry threads\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, making it well suited for through-hole tapping operations\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and 2B class of fit deliver consistent tolerance control for standard threaded fastener assemblies\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; no coolant-through feature required for most general machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application tap for 3\/8-16 through-hole tapping operations.

Always ensure the spindle is fully stopped and the machine is in a safe state before loading or inspecting the tap. Use an appropriate cutting fluid or tapping compound matched to the workpiece material, particularly when tapping stainless steel or hardened steel. Verify that the pre-drilled hole diameter matches the recommended tap drill size for a 3\/8-16 thread before beginning the operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\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: H5\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: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOTAP VC-10 16535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.96 inches (150 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.917 inches (23.3 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 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\u003eWeight\u003c\/strong\u003e: 0.175 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: 1653502908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733155512626,"sku":"1653502908","price":108.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bc9edb55c0d88838044d8d4ef38b68c_cc9cdd8e-e2ea-41d1-9153-8b31ad6b11ab.jpg?v=1788752025","url":"https:\/\/voomisupply.com\/products\/osg-1653502908-spiral-point-tap-3-8-16-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
