Although the general appearance of the machines is similar, we have overhauled these models to make them durable and dependable tools. The major upgrade came in the form of heavy-duty gear systems, including the step-down transmission and a bevel and pinion gear to produce the variable speed range of 700 to 2,500 rpm. Thanks to the high-tech machine center, we have all parts precision-machined to reduce noise and vibration during the application. This upgrade ensures a long-lasting tool life and a comfortable application.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eThe spindle is now specially coated
