It cuts an M12 x 1.50 thread to a 6H class of fit and carries a modified bottoming chamfer, allowing it to thread close to the bottom of a blind hole. The tap is manufactured from cobalt high-speed steel and finished with a TiN coating to extend tool life when working with alloyed and unalloyed steels. With a 40-degree helix angle and three right-hand flutes, it evacuates chips efficiently even in deeper blind holes. Overall length is 3.381 inches. Licensed machinists, tool-and-die makers, and maintenance mechanics use this tap in CNC and manual tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in alloyed and unalloyed steel workpieces. The modified bottoming chamfer provides more usable threads in shallow blind holes compared to a standard plug or taper tap. The fast flute style and 40-degree helix promote reliable chip evacuation without coolant-through capability, making it appropriate for applications where through-coolant is not available. It is part of the GUHRING Series 3974 and is sized for use with a standard tap holder accepting a 0.367-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM12 x 1.50 metric fine thread form to 6H class of fit\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction for improved heat and wear resistance in steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with fast flute style for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread and right-hand flute, Series 3974\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in alloyed and unalloyed steel workpieces.

Ensure the workpiece is securely fixtured and the pilot hole diameter is correctly sized for the M12 x 1.50 thread form before starting. Apply a suitable cutting fluid for steel even though coolant-through is not available on this tap. Inspect the tap for wear or chipping between uses to avoid thread damage or tap breakage in blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.50\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\u003eThread Limit\u003c\/strong\u003e: D5, D6\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.50 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: 3974\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 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: 9039740120070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750946767154,"sku":"9039740120070","price":75.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28ec4d8c6a0abb36078c4a6a86044755_9de15957-eca6-466b-bb66-63a724e6c2be.jpg?v=1788920758","url":"https:\/\/voomisupply.com\/products\/guhring-9039740120070-spiral-flute-tap-m12-x-1-50","provider":"Voomi Supply","version":"1.0","type":"link"}
