Excelente maquina para modelista! Silenciosa ,muy buenos materiales, el mandril te permite diferentes medidas,muy recomendable , llego antes de lo eaperado! Seguiremos comprando productos proxxon!

Comfortable to grip and use for extended periods - tested it on wood carving, rock cutting/engraving and glass etching - found it to be very controllable and easy to use. It's also quieter than I was expecting - which is another plus. Does require the Proxxon Power Transformer which must be purchased separately - would also recommend purchasing the Proxxon Footswitch as it makes operating it a lot safer.

Quello precedente ha (forse) fuso dopo un uso intensivo (a volte per ore continue, poggiandolo solo per farlo raffreddare quando non potevo tenerlo (perche' scottava peggio dell'acqua in ebollizione) quasi giornaliero per circa 5 anni..! Al contrario del suo concorrente (Dr...) questo si impugna bene, e' relativamente leggero e ci si puo' lavorare comodamene. Al contrario del (Dr.. )che dopo 5 minuti ti indolensisce il polso e le dita della mano...col calore si deforma la scocca in plastica/gomma. Difatti lo ho regalato. Un consiglio: evitate di usarlo al massimo dei giri per troppo tempo (come me...) Come si scalda tanto, lasciatelo raffreddare qualche minuto. Potrebbe durare diversi anni se lo trattate bene. Consiglio quello col mandrino autoserrante perche' scoccia parecchio cambiare inserti anche 3 o 4 volte in una seduta di lavoro (e poi te li potresti perdere nel caos del laboratorio)...;-)

I bought the Proxxon Micromot 50 EF Rotary Tool for a CNC micro drill press. This unit is better choice over considering a Dremel motor head for the same application and budget size. No perceptible side to side play of the arbor. Very solid. For example, the bearings are superior quality to eliminate high frequency vibration that often breaks 1/8" shank micro drill bits. The DC power input to the motor also helps in this regard too. Versatility is extended by the EF 50's built in speed control and a mounted-in-metal press to lock the arbor button helps change bits.Because the mounting boss [item #2 in the picture] is a built-in 20mm O.D x 7.25mm wide steel ring instead of plastic, it solidly transfers and protects the output bearings from clamping pressure. No worries about crushing, misalignment or creep of the drill head from a loose mounting grip you're afraid of over-tightening especially from a rapidly moving CNC where the inertia due to accelerating, traversing, then decelerating weight of the motor head may gradually loosen the mounting clamp grip on non-steel mounts.For the interested CNC reader, my CNC micro drill uses this mount but the 3 jaw chuck is about half way recessed up into the bore making changing bits a bit of a hassle. My plan is to change the chuck from a round to a hex style body [then a small spanner can be used to loosen the chuck and change the bit] will eliminate removing the Micromot from the clamp to change the bit. An 8mm thick mount could be machined but for now not in the budget. This is the only downside I found for the nano-wallet CNC micro driller guy/gal using this motor head. ;) But I'm talking budget right ? LOL Okay, moving on...The transition joint between the olive green plastic motor body to the black anodized machined [not cast] aluminum of the arbor piece is engineered in a way to complement the firmness of the metal parts which house the bearings for the output shaft. It's a 18 volt (max) DC motor, but that is easy to solve for the clever owner of one of these. The plug is polarity marked and you can go from there. Or buy the companion Micromot power supply if you want a turn-key situation. For the basement tech hobbyist/hacker, the 50 EF is a great buy cost vs quality over other higher priced dedicated drill motors I could have bought for the same CNC duty I use this for.Disclaimer stuff- No. I'm not a Proxxon affiliate, employee or advertiser.
