It accepts EG0300M03P02 inserts and holds them with a clamp-style mechanism for rigid, repeatable positioning. The toolholder features a 5\/8 x 5\/8 inch square shank and through-coolant capability to direct fluid directly to the cutting zone, improving chip evacuation and extending insert life. Part of the Beyond Evolution series, this left-hand holder is suited for operators running groove widths of 3 mm with a maximum depth of cut of 16 mm (0.63 inches). Machinists and CNC setup technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is used in external grooving and cutoff operations on turned components in both production and job-shop environments. The left-hand orientation suits specific machine configurations and tooling layouts on CNC turning centers. The Beyond Evolution series tooling system is built around consistent insert seating and through-coolant delivery, making it appropriate for high-volume turning applications where tool life and groove accuracy are critical. Compatible insert is the EG0300M03P02, and the holder carries a mount size of 1010.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand external grooving and cutoff orientation for specific CNC turning configurations\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method for secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability directs fluid to the cutting zone for improved chip control and tool life\u003c\/li\u003e\n  \u003cli\u003eAccepts EG0300M03P02 inserts with a 3.0 mm insert seat size\u003c\/li\u003e\n  \u003cli\u003e5\/8 x 5\/8 inch square shank for standard tool block compatibility\u003c\/li\u003e\n  \u003cli\u003ePart of the Beyond Evolution series, designed for consistent grooving performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with EG0300M03P02 inserts.

The machine spindle must be fully stopped and the machine placed in a locked-out, tagged-out state before mounting or adjusting the toolholder. Confirm shank seating depth and clamp torque per the machine tool block specifications before running. Verify coolant line connections are secure before enabling through-coolant flow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: EVSC-T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Beyond Evolution\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal or External\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Groove Width\u003c\/strong\u003e: 3.00 mm (0.1180 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Groove Width\u003c\/strong\u003e: 3.00 mm (0.1180 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 16.00 mm (0.63 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: EG0300M03P02\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 3.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 5\/8 inch (15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\/Diameter\u003c\/strong\u003e: 5\/8 inch (15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3.083 inches (78.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (114.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.92 inches (23.38 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.417 inches (36.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Size\u003c\/strong\u003e: 1010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.453 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153308\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5980939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727162114354,"sku":"5980939","price":282.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bab97515ae5e8a484cbc5fc33619279f.jpg?v=1788674183","url":"https:\/\/voomisupply.com\/products\/kennametal-5980939-grooving-cutoff-toolholder-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
