It cuts an M20 x 1.50 thread to a 6H class of fit and is constructed from powdered metal with a TiN (titanium nitride) coating for extended tool life in demanding materials. The 40-degree helix angle promotes efficient chip evacuation in blind holes, reducing the risk of chip packing. This tap is suited for machinists and tool-and-die professionals working with high-tensile steel in production or job shop environments. It measures 4.921 inches overall and features a right-hand flute with right-hand thread direction.\u003c\/p\u003e\u003cp\u003eThis tap is rated for blind hole threading in high-tensile steel, making it appropriate for aerospace, automotive, and general industrial machining where tight thread tolerance and material hardness demand a premium cutting geometry. The modified bottoming chamfer allows threading close to the bottom of a blind hole. The fast flute style supports higher feed rates in controlled CNC and manual tapping operations. The D6\/D7 thread limit designation indicates the tap's oversize grind relative to nominal thread geometry, which accounts for material springback in tougher workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM20 x 1.50 metric fine thread, 6H class of fit with D6\/D7 thread limit\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip evacuation in blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction with TiN coating for wear resistance in high-tensile steel\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer for threading close to blind hole floors\u003c\/li\u003e\n\u003cli\u003e4 flutes, right-hand thread and flute direction, fast flute style\u003c\/li\u003e\n\u003cli\u003eSeries 4121 tap — no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in high-tensile steel workpieces requiring an M20 x 1.50 metric fine thread at a 6H class of fit.

Ensure the workpiece is securely fixtured and the tapping spindle is properly aligned before operation. Use an appropriate tapping fluid or cutting oil rated for high-tensile steel to protect the tool edge and maintain thread quality. Do not reverse the tap without adequate chip clearance to avoid breakage in blind holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20 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: D6\/D7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\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: High-Tensile Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.921 inches (125.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.652 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.489 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.489 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: 4121\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 9041210200070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728535650610,"sku":"9041210200070","price":156.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f76c1e416766e8755535da551c2c12e8_f6cfc372-5392-4e9a-a9ab-ab6656272b39.jpg?v=1788692893","url":"https:\/\/voomisupply.com\/products\/guhring-9041210200070-spiral-flute-tap-m20-x-1-50","provider":"Voomi Supply","version":"1.0","type":"link"}
