Each reamer is examined under a high - magnification lens to ensure that it meets our stringent standards. 2.Compared with other substrate materials, solid carbide reamer bits have a longer tool life and faster drilling speeds, but are more brittle. Ensure that the workpiece and the machine tool are stable, and use hydraulic chucks, high - quality collet chucks, or shrink - fit chucks. 3.Please adjust the rotational speed, feed rate, and drilling depth according to the actual cutting conditions. When the tool overhangs, please use the minimum required amount. An excessive overhang amount will cause large vibrations, and at this time, the feed rate should be reduced. When the tool overhang length is relatively long, please adjust the rotational speed, feed rate, and cutting depth. 4.Adapt to several kinds of cooling conditions, for example oil mist,water,oil,air cooling.can be used for dry machining.
