Hi, Thanks- Not sure if it would be usable for the mill (still learning! lol)but let me know what you might want for it...
Thanks,
Scott
"I got mine" All of the above -collets included - and a lot more.
But the Burke is only one of three #9 B&S here, the much bigger Quartet's vertical head uses it and the tiny Ellis indexer/DH as well.
My advice?
Grab every scrap of #9 B&S as crosses your radar. There's a lot of it still out there, but it is never as handy as a trip to Big Box when you are in need.
You aren't likely to get "stuck' with it, either. Lot of us running it as wouldn't go near an Are-Ate with a latex-bagged-and-buttered-bargepole.
B&S # 9 has right about DOUBLE the grip and power-transfer capacity as Are-Ate.
Most especially in Weldon-style side-lock holders where the # 9 has stiffer support than an Are Ate solid. Collets in a mill are for the Bird's Ports anyway.
B&S #9 just plain kicks an Are-Ate BirdPort's ass so high up between the shoulder blades it can draw government disability.
B&S #
7 is the one comparable to Are-Ate or MT #2.
#9 is a workhorse.
Just do NOT pull-tight into a
hot spindle. Might stay there for a long while! VERY long while!
Doesn't LOOK all that diffrent from MT, but MT's taper was chosen to reliably eject fron axial loading in a DRILLPRESS, wants to walk right out under milling-cutter side loads and flute impacts, does so unless retention wedge keyed (see hor-bore) or tight drawbar-ed.
B&S taper was chosen to near-as-dammit self-lock and resist milling side loads, even with not a lot of drawbar help. Has done exactly that and rather well, since the 1800's.
