Built on a 0.5 inch square shank, this neutral-cut bit features a micrograin solid carbide tip that delivers fine edge retention and consistent geometry across ferrous and non-ferrous materials. The 60-degree included angle conforms to standard thread profiles, making it suitable for machinists and tool-and-die professionals running production or maintenance threading work. At 3.5 inches overall length with a 0.5 inch tip, the 620-MG follows the industry standard E-8 specification.\u003c\/p\u003e\u003cp\u003eThe 620-MG is suited for threading, chamfering, undercutting, and V-grooving applications on manual and CNC lathes. Its neutral cutting direction makes it appropriate for straight-in plunging cuts. The E-style tool bit format fits standard quick-change and conventional tool post holders accepting 0.5 inch square shank inserts, which are common in job shops, maintenance facilities, and production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide tip provides superior edge retention and wear resistance versus standard carbide grades\u003c\/li\u003e\n\u003cli\u003e60-degree included angle meets standard thread profile geometry for common thread forms\u003c\/li\u003e\n\u003cli\u003eNeutral cutting direction supports straight-in plunging on both manual and CNC equipment\u003c\/li\u003e\n\u003cli\u003eE-8 industry standard designation ensures compatibility with standard tool post holders\u003c\/li\u003e\n\u003cli\u003eMulti-application geometry handles threading, chamfering, undercutting, and V-grooving in a single bit\u003c\/li\u003e\n\u003cli\u003e0.5 inch square shank fits widely available quick-change and lantern-style tool posts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fit for tool holders accepting E-style, 0.5 inch square shank single point tool bits per industry standard number E-8.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or tool-and-die technician. Power down and lock out the lathe or turning center before seating or removing the tool bit from the holder. Ensure the bit is clamped securely and aligned on-center with the workpiece axis before beginning a threading pass. Do not exceed the tool post manufacturer's recommended clamping torque or overhang limits for this shank size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Bit Type\u003c\/strong\u003e: Threading Tool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Bit Style\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: E-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Applications\u003c\/strong\u003e: Chamfering, Threading, Undercutting, V-Grooving\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 620-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743280234802,"sku":"620-MG","price":21.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c1c5fc1cd3d19e47bd58c54f6a1ad80.jpg?v=1788844991","url":"https:\/\/voomisupply.com\/products\/accupro-620-mg-threading-tool-bit-micrograin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
