The Maho 800 was the largest of the Maho range and differed in being not only of very much more massive construction than the smaller models - at 1950 kg it weighed twice as much as the MH600 - but also, in the later version, of a rather different design. Whilst early versions were very like their smaller siblings, with the drive mechanism inside the main column, later machines were radically redesigned with the head enormously enlarged and containing a speed-change gearbox driven directly from a 2.2 kW motor giving 18 speeds from a slowest of 40 to a usefully-fast 4000 r.p.m.. Being intended to tackle heavier jobs both power feed and "rapids" was fitted to every axis of movement (the knee could be moved 500 mm longitudinally and 450 mm vertically) though, unlike the smaller models (and the earlier MH800), the table feed-rate was not variable, being set at 18 individual steps between 8 and 400 mm together with a rapid feed rate of 1000 mm per minute. The head unit, driven along its ways by the same 1.1 kW motor and mechanism as the knee, shared exactly the same number and rates of feed. Whilst the vertical head on early machines was of noticeably lighter construction that that used on the later type it did have the benefit of a decently-sized balanced handwheel (with micrometer dial) to drive the angle setting of the head.
Whilst the punch milling and spiral milling attachments for the MH800 were the same as employed on the smaller models, the three types of table used were all suitably larger, heavier and with more T slots, though with exactly the same range of angular movements..
