It cuts an M2 x 0.40 Metric Coarse thread to a 6H class of fit with a D3 thread limit. Manufactured from powdered metal and coated with a titanium nitride (TiN) finish, this tap delivers heat and wear resistance necessary for work in aerospace alloys and stainless steel. The modified bottoming chamfer allows threading close to the bottom of a blind hole. With a 40-degree helix angle, the flute design evacuates chips efficiently in difficult-to-machine materials. Overall length is 1.752 inches. This is a right-hand flute, right-hand thread tool from GUHRING Series 3909.\u003c\/p\u003e\u003cp\u003eThis tap is suited for precision blind hole threading in aerospace alloys and stainless steel. The 40-degree fast-spiral flute geometry promotes chip ejection upward and away from the cutting zone, reducing the risk of chip packing in stopped bores. It is appropriate for use in CNC machining centers, manual mills, and tapping machines where M2 x 0.40 Metric Coarse threads are required. Machinists and tooling technicians working in aerospace, defense, and precision manufacturing will find this tool well matched to close-tolerance thread requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 x 0.40 Metric Coarse thread form, 6H class of fit, D3 thread limit\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer for threading near the base of blind holes\u003c\/li\u003e\n\u003cli\u003e40-degree fast-spiral flute angle for upward chip evacuation in tough alloys\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction for increased hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life in stainless steel and aerospace alloy applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread and right-hand flute, 3-flute design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in aerospace alloys and stainless steel where an M2 x 0.40 Metric Coarse thread form and 6H class of fit are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed and operated by qualified machinists or tooling technicians familiar with tap selection and thread-cutting procedures. Power down or disengage the spindle completely before mounting or removing the tap from the holder. Use appropriate cutting fluid rated for the workpiece material, particularly when threading stainless steel or aerospace alloys, to prevent galling and premature tool wear. Verify spindle alignment before running to avoid tap breakage in small-diameter blind holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2 x 0.40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\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: D3\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\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\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 Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aerospace Alloy, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.441 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.40 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: 3909\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9039090020000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734139830578,"sku":"9039090020000","price":53.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2202bd6c47d9cf70d521d58cbe9a8fe4.jpg?v=1788761079","url":"https:\/\/voomisupply.com\/products\/guhring-9039090020000-spiral-flute-tap-m2-x-0-40-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
