Built from cobalt high-speed steel with an oxide finish, this plug-chamfer tap is engineered for cutting threads in stainless steel and steel workpieces where toughness and heat resistance are critical. The 4-flute spiral point geometry pushes chips forward ahead of the cut, keeping the flutes clear during through-hole operations. It carries a 6H thread tolerance class with a D4\/D5 thread limit, conforming to Metric Fine standards at M18 x 1.5. Licensed machinists and tool-and-die technicians will find this tap well-suited for production and maintenance threading work.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading in M18 x 1.5 Metric Fine applications. It is appropriate for use in stainless steel and steel materials where cobalt tooling is specified to handle elevated cutting temperatures and work-hardening tendencies. With a 110 mm overall length and a 14 mm shank diameter, it fits standard tap holders and chucks in both manual and CNC tapping setups. The plug chamfer makes it suitable for starting threads from the beginning of a pre-drilled through-hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM18 x 1.5 Metric Fine thread form with 6H class of fit and D4\/D5 thread limit\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction for improved heat resistance and durability in stainless steel and steel\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral point design pushes chips forward, ideal for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides mild lubricity and corrosion resistance during cutting operations\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows threading from the start of a through-hole without a starting chamfer requirement\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, no coolant-through capability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in stainless steel and steel workpieces.

Ensure the workpiece is securely fixtured and that the correct tap drill size for M18 x 1.5 has been used before tapping. Apply appropriate cutting fluid for the material being threaded, particularly when working with stainless steel. Inspect the tap for wear or chipping before each use and replace if thread quality is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M18 x 1.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D4\/D5\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 110 mm (approximately 4.33 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14 mm (approximately 0.55 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2879\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.123 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9028790180070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51736776933682,"sku":"9028790180070","price":98.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e540a1f0b57ae0f01c73332c7776426_398388f9-a99b-4b95-bec5-bffc3fa58008.jpg?v=1788780246","url":"https:\/\/voomisupply.com\/products\/guhring-9028790180070-spiral-point-tap-m18-x-1-5-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
