Built from high speed steel with a bright finish, this tap drives chips forward ahead of the cutting zone, allowing for faster feed rates and cleaner thread formation in production and job-shop environments. It is configured in a plug chamfer style, which distributes cutting load across several leading threads for a balance between starting ease and threading depth. Machinists and tool-and-die technicians are the primary users, and the tap is sized for right-hand 5\/8-18 UNF threads.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole threading operations in ferrous and non-ferrous materials on manual mills, CNC machining centers, and drill presses equipped with tapping heads or tension-compression holders. The 3-flute geometry provides good chip clearance in moderate-length through-holes, making it a practical choice for general production threading where cycle times and thread quality are both priorities. It does not feature coolant-through capability and is intended for conventional flood or manual lubrication setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing re-cutting in through-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer distributes cutting load for smooth engagement and controlled thread start\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, Class 2B thread limit H5 for standard UNF tolerance fits\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating for straightforward regrinding when worn\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip evacuation and tool body strength\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting right-hand 5\/8-18 UNF internal threads in through-hole configurations consistent with Class 2B fit requirements.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of taps should be performed by a qualified machinist following standard threading procedures. Secure the workpiece firmly before threading and ensure proper alignment between the tap axis and the pre-drilled hole to avoid tap breakage. Use an appropriate cutting fluid or tapping compound for the workpiece material, and never attempt to reverse a broken tap without proper extraction tooling. Follow shop safety protocols and applicable OSHA guidelines when operating rotary cutting equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4800 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: K008571AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728782262578,"sku":"K008571AS","price":71.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b00f1ef356f9e8576c4d42a3d9578df.jpg?v=1788696170","url":"https:\/\/voomisupply.com\/products\/hertel-k008571as-spiral-point-tap-5-8-18-unf-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
