I bought two MultiPro models (field coil) with speed control.
One has a rubberized body. I bought both of them at Home Depot($59).
Both have seen several sets of carbon brushes. The Dremel will run for
hours straight at 3-1/2 (12,000RPMs) Make sure you have good airflow!!
There are many clones out there that suck. The newer Dremel again
uses magnets instead of a field coil. This give better torq. Older
Dremels had magnets. My old Dremel (1984)is mounted in a Dremel Drill
Press. It is very old. The table lifts up on the drill press.
To mount a Dremel you unscrew the finger grip to reveal mounting
threads. Grip the unit at the threads and the body. When done
correctly you can flex the bit without the Dremel moving. When
designing a CNC machine it is done from the cutting bit out. Holding
the Dremel in the midsection with a 1/2" wide clamp shows you have not
done your homework. A longer "V" block mount with clamp would be
acceptable. Drilling is not Milling.
