Manufactured from high speed steel with a bright uncoated finish, it is built for durability and dimensional consistency in light-duty tapping operations. The plug chamfer style, with a standard 3-5 thread lead, provides a balanced starting action suited to through-holes and blind holes with adequate clearance. The 4-flute straight-flute geometry delivers clean chip evacuation in a variety of ferrous and non-ferrous materials. With an overall length of 2.375 inches and a thread length of 0.875 inches, this tap fits standard tap wrenches used in machine shops, maintenance facilities, and field service environments.\u003c\/p\u003e\u003cp\u003eThis tap is intended for hand tapping operations where a standard plug chamfer is required to thread M4.5x0.75 metric coarse holes. It is a common choice for maintenance, repair, and overhaul work, as well as prototype machining and production tapping in low-volume settings. The D2 thread limit designation controls the pitch diameter tolerance of the finished thread, making it appropriate for general-purpose metric thread fits. It is used by machinists, millwrights, and maintenance technicians across industrial and manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM4.5x0.75 metric coarse thread form with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for versatile use in through-holes and adequately deep blind holes\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute design supports chip clearance and thread form accuracy\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides good wear resistance across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains close dimensional tolerances out of the box\u003c\/li\u003e\n\u003cli\u003eD2 thread limit for general-purpose metric thread fits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use hand tap for standard M4.5x0.75 metric coarse tapping applications using common tap wrenches and holders sized for the 0.194-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHand tapping should be performed by a qualified machinist or maintenance technician following standard tapping procedures. Secure the workpiece firmly before starting and use an appropriate cutting fluid to reduce friction and extend tap life. Back the tap off periodically to break chips and prevent binding. Never force a tap that has stalled, as high speed steel taps are brittle under torsional overload and may fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4.5 x 0.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K020137AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753243541810,"sku":"K020137AS","price":30.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d5613dcf55ce21d8d6d8cd074e5d4f8.jpg?v=1788934321","url":"https:\/\/voomisupply.com\/products\/hertel-k020137as-m4-5x0-75-plug-hand-tap-hss-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
