259660 Glen Canaday <gcanaday@g...> 2016‑07‑23 Re: Saw teeth and a Millers Falls No. 4
The MF #4 came with a set of diamond-shaped spade bits of different sizes.
However, they all had a 3/32 shank size. In modern bits, it accepts only
that size twist drill.

The "chuck" is only a hole in the spindle with sawn (or milled) slots to
allow it to act as jaws..essentially, an early collet. It had a threaded
nut that was tapered on the inside to apply closing pressure.

There are probably a bazillion pictures on the net of them; my personal
unit is a bad example as it has a collet on there from something else
entirely...I think, and so I've been told.

The 4D came with an actual chuck in tiny size and was able to grab
different shank sizes.

GG,
 My take on the MF No. 4 is that it never had a "chuck" it simply accepted
a drill bit with a base the size of the socket on the drill and the keeper
nut was made to clamp on the bit where it tapered. Using the same bits you
used in a push-drill. I have only ever seen one type of bit in a No. 4 and
it was just a pointed bit with no cutting flutes or anything. I also have
another drill that is the same as a No. 4 but is not a MF and it is the
same. JMTC...
