It accepts collets ranging from 1\/8 inch to 7\/8 inch, providing broad compatibility with standard tooling for a wide variety of milling and drilling operations.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes this mill include a coolant pump with the built-in coolant tank?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe JTM-4VS features an internal coolant tank built directly into the casting base, designed for use with a coolant system. However, the coolant pump is not included and would need to be sourced separately to take advantage of the integrated tank.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat is the spindle speed range, and how is the speed adjusted on this machine?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe JTM-4VS offers a variable spindle speed range of 60 to 4,200 RPM. The variable speed design allows the operator to dial in the appropriate cutting speed for different materials and tooling without changing belts or gears, supporting efficient and versatile machining across a broad range of applications.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat does the 3-axis Newall DP700 DRO system provide on this mill?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe integrated Newall DP700 Digital Readout system provides real-time position feedback on all three axes  -  X, Y, and Z (Knee)  -  allowing machinists to make precise, repeatable cuts with confidence. Combined with the X, Y, and Z-axis powerfeeds, the DRO significantly reduces setup time, minimizes manual measurement errors, and improves overall machining accuracy and productivity.\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003c\/div\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":40249087262881,"sku":"JT9-690093","price":23412.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0398\/5188\/4705\/products\/690093_main_1417cc24-1ed2-4f59-8289-c7e5853ccd6c.png?v=1624988855","url":"https:\/\/factorydirectsupply.com\/products\/jet-690093","provider":"FactoryDirectSupply.com","version":"1.0","type":"link"}
