{"product_id":"jinme-j3-plus-4hole","title":"Jinme J3 Plus - 4hole","description":"\u003cp\u003e\u003cspan\u003eThe Jinme J3 Plus (4-hole) High-Speed Handpiece is a push-button turbine handpiece built with a stainless steel body and a standard-size head. It runs on 0.2–0.3 MPa working air pressure at a rotational speed of 350,000–420,000 RPM, with operating noise kept at or below 60dB and water flow between 90–110 mL\/min for cooling during cutting. An internal constant-pressure regulator is designed to protect internal components from damage caused by excess air pressure, while a fast-stop mechanism brings the bur to a complete halt within about 2 seconds of release, supporting safer bur changes. An anti-suction (anti-retraction) design helps prevent oral fluids and debris from being drawn back into the handpiece, reducing cross-contamination risk between patients; the manufacturer reports spindle-holding degradation of roughly 2% after extended testing of its auto-chuck push-button spindle. \u003c\/span\u003e\u003c\/p\u003e","brand":"Jinme","offers":[{"title":"Default Title","offer_id":42894495809616,"sku":null,"price":140.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/1989\/3584\/files\/JinmeJ3Plus-4hole.png?v=1788447730","url":"https:\/\/allpracticesolutions.com\/products\/jinme-j3-plus-4hole","provider":"APS","version":"1.0","type":"link"}
