With this device are the ghosts. Personally, I get to about 1-2 hours test UDN adjustment phase so super clear. It is admittedly not easy to find the right combination by tightening torque of the screws eliminate the game when lowering but with enough grease and a little skill and patience you can get a satisfactory for hobby use TOTAL device. Solid material, Heavy weight and smooth-running crank. Built for quite a long time it seems to me. 24 mm for SDS-PLUS tools, in conjunction with Bosch SDS-plus adapter with chuck, 2607000982 and the Berlan machines at me with a Makita HR2450 hammer drill - vice 100mm BMSS100 used. Have already used for boring wood cores by Forstner drill bits and drilling of resin and hardwood. Everything went Einwandfrie across the stage. Definitely easier to space-saving, practical and MEN also more accurate than a drill press at 300 euros. For my purposes ideal. Take your time when adjusting and it fits. Impeccable.
