Hi Gary,toggle quoted messageShow quoted text
Grizzly has them in drawbar style MT3 for 3/16, 3/8, 1/2, 5/8, and 3/4 size endmills. They are on page 462 of the Grizzly catalog. Part numbers are G9540 through G9544 inclusive, prices are 16.96 for the 2 smaller and 17.95 for the three larger sizes.
These are for a standard imperial drawbar(3/8-16), metric drawbar for these is M12-1.75. Grizzly has them also.
There's always the option of MT3 collets available. I won't use a collet to hold any tool with helical edges (at least not in shanks < 3/4 inch), but some folks seem to get away with it. Little Machine Shop sells a pretty nice set of Chinese MT3 collets for around $70.
