Built from vanadium high-speed steel (HSS-E) with a steam oxide coating, this plug-chamfer tap handles through-hole applications where chips are pushed ahead of the cutting edge rather than packed in the flute. The 3-flute configuration balances chip clearance and cutting stability. At 4.921 inches overall length with a 2-inch thread length, it fits standard tap handles and CNC rigid-tapping setups. Class of fit is 6H, producing threads within standard tolerance for most metric fastener assemblies.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production and maintenance tapping in ferrous and non-ferrous materials including aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron. The plug chamfer makes it appropriate for through-hole applications where tool entry and chip evacuation are straightforward. It is used in machine shops, maintenance facilities, and job sites where metric fine threads are required. The right-hand cut and non-coolant-through design fit conventional drill press, tapping machine, and CNC machining center operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM20x1.50 metric fine thread form, 6H class of fit for standard tolerance metric assemblies\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel (HSS-E) construction for increased wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and improves chip flow during cutting\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, suited for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances cutting load and chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement tap for M20x1.50 metric fine through-hole applications in OSG Series 259.

Secure the workpiece fully before beginning; never tap freehand in materials that can grab or deflect the tool. Use a cutting fluid appropriate to the workpiece material to extend tap life and improve thread finish. Inspect the tap for chipping or wear before each use, as a damaged cutting edge can result in an oversized or torn thread and potential 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: M20x1.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\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: Plug\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: Vanadium High-Speed Steel (HSS-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.921 inches (125 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.652 inches (16.568 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 17.4625 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\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: 259\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.445 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2593401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739732967730,"sku":"2593401","price":227.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc9f16692e8f2dc7e03f83a78fcfd15d.jpg?v=1788818326","url":"https:\/\/voomisupply.com\/products\/osg-2593401-spiral-point-tap-m20x1-50-metric-fine-6h","provider":"Voomi Supply","version":"1.0","type":"link"}
