Built from high-speed steel, it carries a 3-flute geometry and a bottoming chamfer, making it well-suited for threading close to the bottom of blind holes where full thread depth is required. With an overall length of 1-15\/16 inches and a thread length of 5\/8 inches, the 1013202 fits standard tap handles and machines used in production and maintenance environments. Class of fit is 2B and 3B, with an H2 thread limit for consistent tolerance control. Right-hand thread direction is standard.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in general machining, toolroom, and maintenance applications where 5-40 UNC threads are required. Its straight flute design is effective in through-holes and short blind holes where chip clearance is manageable. The bottoming chamfer allows thread cutting to begin within 1 to 2 threads of the hole bottom. Machinists and maintenance technicians working with aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel will find this tap appropriate for their material range. It is a single-piece item with a minimum order quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e3-flute straight flute geometry suitable for short-chipping materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across common ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for consistent 2B and 3B class-of-fit results\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 5-40 UNC standard\u003c\/li\u003e\n\u003cli\u003eCompact 1-15\/16 inch overall length fits standard tap holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 5-40 UNC threads in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces.

Ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill size for 5-40 UNC before beginning. Use appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. For machine tapping, verify spindle speed and feed rate are appropriate for the material and tap size before starting the cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\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: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B and 3B\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\u003eThread Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\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: 1013202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740124348722,"sku":"1013202","price":25.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/135911521600ec3936c0e6acefc6ad9a.jpg?v=1788822578","url":"https:\/\/voomisupply.com\/products\/osg-1013202-straight-flute-tap-5-40-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
