Built from cobalt high-speed steel with an oxide finish, it cuts M16x2 metric threads to a 6H class of fit with consistent accuracy. The 40-degree helix angle and fast flute style work together to evacuate chips upward out of the hole, making this tap well-suited for difficult-to-machine materials where chip packing is a concern. With a 110 millimeter overall length and a 20 millimeter thread length, it fits standard tapping chucks and CNC toolholders used in production and job-shop environments. Licensed machinists and tool-and-die trades install this tap in machining centers, drill presses, and manual tapping setups.\u003c\/p\u003e\n\u003cp\u003eThis tap is built for blind hole threading applications across a broad material spectrum. Suitable workpiece materials include alloy steel, alloy tool steel, aluminum alloy, case-hardened steel, cast iron, ductile iron, free-cutting steel, heat-treated steel, malleable cast iron, stainless steel, structural steel, and tool steel. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard plug chamfer, making it a practical choice when full thread depth near the hole bottom is required. It is part of the GUHRING Series 5717 spiral flute tap line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM16x2 metric thread, 6H class of fit, D7 thread limit for precise tolerance control\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with fast flute style for efficient upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and provides light corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread and right-hand flute direction for standard tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application tap for blind hole threading in M16x2 metric thread applications across alloy steel, stainless steel, cast iron, aluminum alloy, and related materials listed under GUHRING Series 5717.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following applicable shop safety procedures. Secure the workpiece rigidly and ensure the tap is held in a properly sized tapping chuck or floating holder to prevent misalignment and tap breakage. Apply appropriate cutting fluid for the workpiece material, as dry tapping in steel significantly shortens tool life. Do not force the tap if resistance increases unexpectedly — back off to clear chips before continuing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M16x2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 2.00 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: D7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 110.00 mm (4.3307 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 20.00 mm (0.7874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm (0.4724 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 14.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 9.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: 5717\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 9057170160000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747516121394,"sku":"9057170160000","price":65.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79b6eed0a1458057ad5cfd4e502ceab9_2b8083a4-621f-46cd-9dac-9485d1111975.jpg?v=1788881713","url":"https:\/\/voomisupply.com\/products\/guhring-9057170160000-spiral-flute-tap-m16x2-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
