It features a modified bottoming chamfer, allowing threads to be cut close to the bottom of a blind hole. The 42-degree helix angle and fast flute style help evacuate chips upward out of the hole during the tapping operation, reducing chip packing and improving thread quality. Manufactured from powdered metal and finished with a TICN coating, this tap offers increased surface hardness and wear resistance compared to standard high-speed steel options. It is suited for production environments where tool life and consistency matter.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in machine tapping applications on CNC machining centers, drill presses, and tapping machines. The right-hand flute and right-hand thread configuration match the standard tapping direction for most shop setups. The 2B class of fit produces threads within the tolerance range required for most general-purpose fastener assemblies. It is commonly installed by machinists and toolroom technicians working in manufacturing, maintenance, and fabrication operations where UNC threaded holes are required in steel, cast iron, and similar ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form with 2B class of fit for general-purpose tolerance requirements\u003c\/li\u003e\n  \u003cli\u003e42-degree helix angle with fast flute style for efficient upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading close to the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides a finer grain structure and improved toughness over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTICN coating increases surface hardness and lubricity, extending tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit ensures consistent pitch diameter control within tight tolerance bands\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cutting tool replacement for 3\/8-16 UNC spiral flute tapping applications.

Ensure the tap is properly aligned with the drilled pilot hole to avoid tap breakage or thread distortion. Use an appropriate cutting fluid or tapping compound for the workpiece material; do not run the tap dry in ferrous materials. De-energize and lock out the machine before changing or inspecting taps, following applicable shop safety procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\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\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TICN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40125-01C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732550058290,"sku":"40125-01C","price":65.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3e2906c1365b66d2566ac2e064784e9.jpg?v=1788744346","url":"https:\/\/voomisupply.com\/products\/accupro-40125-01c-spiral-flute-tap-3-8-16-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
