Feb 21, 2004· The Benchmaster is a good little horizontal mill, but it is little. The vertcal head for these is rather limited IIRC. You can convert any of the smaller horizontal mills to a high speed verical head like the Rusnok. (1/4hp, "Y" collets up to 1/2", 280 - 4800 rpm, and 1.5" of quill travel.) I had one on my Benchmaster, but it was lacking in Z.
