Reamer

[Vann]

Hi all. I picked up this tapered reamer recently - just 'cause it looked interesting

It's 3/8" at the start of the taper, and 2 1/4" at the large end - all over 3 1/2" of length. That seems an extreme taper to me. Half way between what I would have thought a normal taper (for chairs etc.), and a countersink. Obviously intended for use in a brace.

Anybody know what branch of woodworking it would be for?

Cheers, Vann.

Oops, forgot to add: it's marked "UNION TOOL CO/ORANGE MASS USA"

Cheers, Vann.

Plumbing, it's a pipe reamer used to remove the burr from the inside of pipe after cutting.

Thanks, that makes sense. I was looking for a woodwork use (not metalwork), probably because of the tapered square shank... #-o
