|Carving Tool||Generic||1/8" and 3/16"||15,000 -- 20,000 r.p.m.||110v AC||The Chinese Foredom knockoff - This is a pretty good little spindle. For the most part you can only get to 3/16" shank, which isn't really an advantage over 1/8" because the bits are so hard to find, but what it does get you is "off-site" power. It uses a flexible wand connected to an AC motor. The motor turns between 15-20k RPM. I used one of these for about 6 months before it died. You can see it in my phone dock video (see list of videos below). The foredom knockoff is to-date my favorite choice *IF* I could get it with a 1/4" collett. It's good enough that I've contemplating buying a non-knockoff foredom handpiece just to see if it's any better, but at $355 I'm not sure that's ever going to happen. Because of what EJ was talking about (mounting the majority of the weight) off the machine, gives some great advantages. One that wasn't mentioned is the fact that the tool itself is closer to the z-axis, creating less of a lever arm.|
|DC Spindle||Generic||180 Watts||15,000 -- 20,000 r.p.m.||48v||The 180w DC spindle (48v) - This is ninja quiet! And IMO does a nice job with simple engraving features, but is SERIOUSLY lacking in the power category. Don't plan to cut much (or anything) with this. I don't do PCB engraving, but imagine this thing would be great.|
|DC Spindle||Generic||1/4" ER-11||300 Watts (6.25 amps)||r.p.m.||48v||The 300w DC spindle (48v) - This is the second quietest spindle on the list. It's still lacking in power compared to even the knockoff dremel, but can manage to cut through most woods & plastics if treated nicely (1/32" (0.79375 mm) depth pass). It also has a 1/4" ER-11 collett option, but IMO is worthless because of the lack of power. Blog post about it here.|
|Palm Router||brand-name||1/4" (Other sizes available from Precise Bits)||672 Watts (5.6 amps)||16,000 -- 35,000 r.p.m.||110v||3.3 lbs.||The Bosch Colt - This thing is a MONSTER! It's loud as hell, and weighs more than any of the others (excepting the heaver Dewalt DWP611), and is pretty big, but it can really tear some stuff up. Cat saw it run first hand on one of my prototype machines when he was in Chicago last month and could attest to it's sheer power. I used a 1/4" 2 flute Onsrud bit and tore through a piece of maple at 1/4" depth pass without the Colt even flinching. Discussion in the forums here. European model is GKF-600. Notable features include:
||K2CNC Bosch Colt Router Mount|
|Mini spindle||generic||ER20||800 Watts (7.27 amps)||6,000--24,000 r.p.m.||110v||The next one on my list is the 800w water cooled VFD. At $271, it's pricey, but this one runs off 110v, so the need for a 220v drop isn't required. The 220v versions are about the same price, but most people don't have 220v available and would have to pay an electrician to get it installed.||ali-express|

Collets and Adapters
There are some vendors which make collets for specific machines as listed above.
There are also industry standard forms which some machines use allowing for a certain level of interchangeability.
In addition, it is possible to use adapters to allow a collet to hold a bit which otherwise would not fit:
- Trend CLT/SLV/3263 Collet sleeve 3.2mm to 6.35mm (eBay UK)
- MLCS steel adapter bushing 1/8"
- Elaire Corporation Reducing Collets
It's also possible to directly control a spindle using the electronics: Spindle Control.
Single-speed spindles can also be controlled using a router speed control as noted in Less Power on the Dewalt DW660 page.
