Ground from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance in general-purpose threading operations. It features a 3\/4-10 UNC thread form with a left-hand thread direction and an H3 thread limit, making it suited for applications that demand a controlled fit with slight oversize tolerance. Four straight flutes provide good chip clearance in through-hole and shallow blind-hole applications across ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, maintenance, and production environments where 3\/4-10 UNC left-hand internal threads are required. The bottoming chamfer — typically 1 to 2 threads of lead — allows threading to within a few threads of the bottom of a blind hole, making it a finishing tap used after a taper or plug tap has already started the thread. It is appropriate for use in drill presses, CNC machining centers, tapping heads, or manual tap handles in both production and repair contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eLeft-hand thread direction — intended for left-hand thread applications only\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for controlled tolerance fit\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — suitable for use with cutting fluids in standard threading operations\u003c\/li\u003e\n  \u003cli\u003eFour straight flutes for chip evacuation in shallow or through-hole threading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 3\/4-10 UNC left-hand internal threads.

Always ensure the workpiece is securely fixtured and the tap is properly aligned with the pre-drilled hole before applying torque. Use an appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and improve thread quality. As a bottoming tap, it is intended for use after a taper or plug tap has already established the thread in the hole — driving a bottoming tap into an unprepared hole significantly increases the risk of tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.7 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04917118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715192815922,"sku":"MSC-04917118","price":62.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c20421fdce584facb7b9da89d90aac2.jpg?v=1788510369","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04917118-tap-3-4-10-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
