It produces a 7\/16-20 UNF right-hand thread with a plug chamfer, making it suited for through-hole tapping applications where chips are pushed ahead of the tap rather than backed out. The tap is manufactured from powdered metal (grade PMT15) and finished with a TiCN coating to extend tool life in demanding materials. It carries a 2B class of fit and an H5 thread limit, ensuring threads meet standard tolerance requirements for most fastener applications.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in machine tapping operations across general manufacturing, maintenance, and fabrication environments. The spiral point design is best suited for through holes, where the chip stream can exit cleanly ahead of the cutting zone. Material compatibility is broad, covering alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel. It is used by machinists, tool-and-die makers, and maintenance technicians working with CNC machining centers, drill presses, and tapping machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-20 UNF thread form with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction (grade PMT15) for improved wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive and hard materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (approximately 3-5 threads) suited for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and 2B class of fit for standard tolerance internal threads\u003c\/li\u003e\n\u003cli\u003e3-flute spiral point geometry for efficient chip evacuation in through-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with through-hole tapping operations in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel.

Ensure the workpiece is securely fixtured and the spindle speed and feed rate are set per the material being tapped before engaging the tool. Use appropriate cutting fluid or coolant for the workpiece material to reduce heat and extend tool life. Inspect the tap for wear or chipping before each use and replace if cutting edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eMaterial\u003c\/strong\u003e: Powdered Metal (PMT15)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.937 inches (100 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.858 inches (21.8 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 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: 16515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.109 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: 1651503008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742931255602,"sku":"1651503008","price":80.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d239a01f1716cad39e722229dbf22ee8.jpg?v=1788840552","url":"https:\/\/voomisupply.com\/products\/osg-1651503008-spiral-point-tap-7-16-20-unf-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
