Built from cobalt high-speed steel with an oxide finish, this tap offers improved heat and wear resistance compared to standard HSS tooling. It features three flutes and a D6 thread limit with a 6G class of fit. Overall length is 2.4803 inches with a thread length of 0.2953 inches and a shank diameter of 0.1772 inches. It is part of the Guhring Series 5720 and is suited for use in CNC machining centers, drill presses, and hand-tapping setups where precise metric threading is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading across a broad range of materials. It is suited for production and maintenance machining environments where M4 metric coarse threads are needed. Compatible material applications include aluminum, aluminum alloys, free cutting steel, structural steel, heat treatable steel, case hardened steel, stainless steel, cast iron, sulfured steel, and tool steel. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard taper or plug chamfer, making it useful in tight-tolerance assemblies where full thread depth is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt HSS construction with oxide finish for increased heat resistance and lubricity\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral point geometry pushes chips forward ahead of the tap during cutting\u003c\/li\u003e\n  \u003cli\u003e6G class of fit with D6 thread limit for consistent, tolerance-controlled threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through — suited for standard tapping setups\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 2.4803 inches fits standard tap holders and collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for M4 x 0.70 metric coarse blind hole threading applications across aluminum, aluminum alloys, case hardened steel, cast iron, free cutting steel, heat treatable steel, stainless steel, structural steel, sulfured steel, and tool steel as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC rigid-tapping cycle. Ensure the workpiece is securely fixtured and the tap is properly aligned to the hole axis before engagement to avoid tap breakage. Apply appropriate cutting fluid for the workpiece material before and during the tapping operation. Inspect the tap for wear or chipping before each use, particularly when working in harder materials such as stainless or tool steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4 x 0.70\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D6\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: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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\u003eOverall Length\u003c\/strong\u003e: 2.4803 inches (63.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.2953 inches (7.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1772 inches (4.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.5315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 3.40 mm\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: 5720\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 9057200040000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727168930098,"sku":"9057200040000","price":31.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65878b1fd776e9b4e78e5a28c2963341.jpg?v=1788674263","url":"https:\/\/voomisupply.com\/products\/guhring-9057200040000-spiral-point-tap-m4x0-7-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
