00:00If you've ever chucked up an end mill and watched your cut wander all over the place,
00:04chances are it wasn't your spindle, it was your collet.
00:07I've spent the last few weeks digging through the cheapest, best-rated ER collet sets I could find,
00:12and honestly, the prices I stumbled across kind of shock me.
00:15So here are the top 5 ER collet chuck sets for spindles,
00:19from a $3 single collet all the way up to a full precision kit.
00:23Let's get into it.
00:25First up is the XCAN spring collet, and this one's the budget hero of the whole list.
00:30You pick your size ER 11, 16, 20, 25, 32, or 32, and it lands on your bench for around
00:38$3.
00:39$3.
00:41That's less than a coffee.
00:43Now, obviously you're not getting a full set at that price, but that's exactly why I like it,
00:48if you only ever run one or two shank sizes, why pay for a box of collets you'll never touch?
00:53Nearly 5,000 sold with a 4.9 rating tells you people are actually happy with them.
00:59Great as a replacement, or as a spare for the size you always seem to lose.
01:04Next is the Precision ER AAA collet set at around $1276, and this is where things get interesting.
01:10You've got the choice between AA grade at 8 microns of runout, or a grade at 15 microns,
01:16and for under $13, getting AA grade accuracy is genuinely surprising.
01:208 microns is tight enough for detailed engraving, aluminum work, small diameter end mills,
01:26the stuff where sloppy grip ruins your finish.
01:29It's sitting on a perfect 5-star rating with over 4,600 sold.
01:33If you want one set that just quietly works and you don't want to think about it again,
01:38this is a really easy recommendation.
01:40Coming in third, we've got the full ER 11 through ER 40 set with the AA and upgrade option,
01:46and this is the one for people who take their tolerances seriously.
01:49The upgrade gets you down to 5 microns of runout, that's about as tight as you'll realistically
01:54need on a hobby or small production spindle.
01:57It's the most expensive on the list at $20.49, but think about what that actually buys you,
02:03a complete range of collet sizes with premium accuracy.
02:07Better tool life, better surface finish, less chatter.
02:11Perfect 5 stars, 4,600 sold.
02:14If you're cutting parts that have to actually measure right, spend the extra $10.
02:19Fourth on the list is another precision ER AAA set, this one at $1470.
02:25Same AA and a great options, same ER 11 to ER 40 coverage, and I'm including it because
02:30sellers on these platforms go in and out of stock constantly, and having a second solid
02:34option at basically the same spec is genuinely useful.
02:38It's also got a perfect 5-star rating with over 4,300 sold, so the quality is clearly consistent.
02:45If the cheaper listing is sold out or the shipping to your country is slow, grab this one instead.
02:51Same collets, same accuracy, no compromise.
02:55And rounding things out at number 5 is the ER Spring Collet Chuck set with the 15 and 8 micron
03:00options, at $10.62.
03:03This is the cheapest complete set on the list, and that makes it the perfect starter kit.
03:08If you've just built a CNC router, picked up a used mill, or you're setting up a little
03:13engraving machine, this gets you the whole size range for about the price of lunch.
03:175 stars, 4,000 plus sold.
03:20Go with the 8 micron version if you can, it's usually only a dollar or two more and it's
03:25absolutely worth it.
03:27All 5 of those are linked down in the description, and prices on these do move around, so it's
03:32worth checking before you buy.
