Compatible collet sizes range from 1\/8 to 7\/8 inch, giving you broad flexibility for end mills, drill chucks, boring heads, and other common toolholders.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eHow does the pneumatic power draw bar improve the milling workflow?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe pneumatic power draw bar allows operators to engage and release R-8 toolholders quickly without manually striking a draw bar with a wrench. This reduces tool change time significantly, minimizes wear on the spindle and toolholders, and improves consistency when changing between cutting tools during production runs.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat is the purpose of the internal coolant tank built into the casting base?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe internal coolant tank is integrated directly into the casting base of the machine, providing a self-contained reservoir for a coolant system. This design keeps the coolant supply close to the cutting zone, helps manage chip removal, prolongs tool life, and maintains workpiece temperature during extended machining operations. Note that the coolant pump is not included and must be sourced separately.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat does the one-shot lubrication system do, and why does it matter for machine longevity?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe one-shot lubrication system allows the operator to distribute oil to all critical bearing surfaces, ways, and sliding components with a single pump action. This simplifies the maintenance routine, ensures consistent lubrication across the precision hardened and ground ways and table, and significantly extends the service life of the machine's moving components.\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003c\/div\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":40249107087521,"sku":"JT9-690009","price":20690.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0398\/5188\/4705\/products\/690009_main_3c3f3915-1281-4f9b-ba14-5feeaea54e54.png?v=1624988993","url":"https:\/\/factorydirectsupply.com\/products\/jet-690009","provider":"FactoryDirectSupply.com","version":"1.0","type":"link"}
