I'm not a machinist, so I don't know much about these. Dad had a small box of these, and I need to get rid of them.
They're new, and unopened (except a couple to take photos). The box is labeled:
MT3-SLA5/8-35
And the holder is labeled:
MTB3-SL15.875
MADE IN TAIWAN
I have 13 of these, and 2 where the box is labeled:
MT4-SLA3/4-60
$20 EA and $10 shipping, regardless of quantity.
