It accepts collets ranging from 1\/8 to 7\/8 inch, giving you broad compatibility with end mills, drill chucks, boring heads, and other common tooling.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat is the spindle speed range, and is it continuously variable?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes  -  the JTM-4VS is a variable speed mill with a spindle speed range of 60 to 4,200 RPM. This wide range allows operators to dial in the correct cutting speed for a variety of materials and tooling diameters without the need to change belt positions.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes this mill include a coolant pump?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe machine features an internal coolant tank built directly into the casting base, which is designed for use with a coolant system. However, the coolant pump is not included and must be purchased separately.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat does the one-shot lubrication system do, and why does it matter?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe one-shot lubrication system allows the operator to simultaneously lubricate all ways and lead screws with a single pump action. This simplifies routine maintenance, helps ensure the ways stay properly lubricated, and contributes to the long-term precision and service life of the machine's precision hardened and ground ways and table.\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003c\/div\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":40249093849249,"sku":"JT9-690408","price":20907.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0398\/5188\/4705\/products\/690408_main_2a18e479-b435-4a86-8508-bab58e334bc2.png?v=1624988901","url":"https:\/\/factorydirectsupply.com\/products\/jet-690408","provider":"FactoryDirectSupply.com","version":"1.0","type":"link"}
