Built from vanadium high-speed steel (HSS-E) and finished with a steam oxide coating, it provides improved lubricity and corrosion resistance during threading operations. The spiral point geometry pushes chips ahead of the tap and out of the hole, making it well suited for through-hole applications. With 3 flutes and a D6 thread limit, this tap holds tight tolerances for precision threaded assemblies. Thread length is 1-13\/16 inches, and the shank diameter measures 0.542 inches. Right-hand thread direction is standard.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in through-hole threading operations on hardened steel, low-carbon steel, medium-carbon steel, and stainless steel workpieces. It is commonly used in machining, maintenance, and repair environments where metric fine threads are required. The plug chamfer provides a gradual thread lead-in, distributing cutting forces across several leading threads. It is appropriate for both CNC and manual tapping applications where chip evacuation forward through the hole is feasible.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM18x1.50 metric fine thread form for precision fastener applications\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel (HSS-E) construction for durability in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and provides light corrosion protection\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eD6 thread limit for consistent, close-tolerance thread fit\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement, non-interrupted thread profile\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in hardened steel, low-carbon steel, medium-carbon steel, and stainless steel.

Ensure the workpiece is securely fixtured and the drill hole diameter is correct for M18x1.50 before tapping. Apply appropriate cutting fluid for the workpiece material, particularly when threading stainless steel. Do not reverse the tap under power without confirming the setup is rated for reversing operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M18x1.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Fine\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\u003eThread Limit\u003c\/strong\u003e: D6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-13\/16 inches (3 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.542 inches (13.7668 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 15.875 mm\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\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hardened Steel, Low-Carbon Steel, Medium-Carbon Steel, Stainless Steel\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\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 342\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.275 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: 1773301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754739695922,"sku":"1773301","price":180.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f037cfbe3d1872fe259a871295acd92f_7e81a88a-6420-439e-ba90-5c25995fff05.jpg?v=1788948251","url":"https:\/\/voomisupply.com\/products\/osg-1773301-spiral-point-tap-m18x1-50-metric-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
