Free .pdf saw owner's manual: Write Bob@theaerosmith.comPer Bill Wilson, Dremel expert: "The 580-2 is a later model and has a few minor upgrades. The Motor shaft and pulley diameter is approx. 1/8 thicker than the earlier 580 model. Also the front hub with gear has a baked on Grey enamel rust proof finish. The cheap chrome front knob on the 580 model tends to be prone to rust. The hardware screws that attach the motor frame assembly are also anodized screws rather than chrome screws. Other than these differences the saws are identical in every other way."

Carbide blades: If you don't do ANYTHING else to you your Dremel saw, buy carbide blades for it. They are the single-most huge improvement you can make to it, a sound investment. I've recommended Harbor Freight's carbide blades for many years as they have been an excellent buy, a third the cost of MicroMark's, and every bit as good in my opinion. Recently they discontinued them, leaving people stuck with the very high priced MicroMark blades or chancy buy off eBay. I lucked into source for a really great set of blades (20 and 40 tooth) but they only sell wholesale, 25 minimum, so 50 blades to get 20 and 40 tooth. I felt obligated to have them available, so bit the bullet, made the investment and have them on hand. Didn't want to be in "business", but I keep them right on the desk, packed and ready to go. You can send a PayPal (Bob@theaerosmith.com), and it goes in the mail.
August 2013: Price change. 20-tooth and 40-tooth, $45 a pair, post-paid...MicroMark's no longer sells a 20-tooth blade, necessary for long ripping and other heavy cuts. Their 40-tooth blade is $33.50 + tax and $10 shipping. MM's are fine blades, just a little pricey... The blades I have are very high quality. Single 40 tooth blade shipped at $27.50, two for $50. 20 tooth blades are $18.50 singles, $35 for two. Write me about other quantities. The Dremel manual in .pdf is free, of course. Has been for years now. Over 600 given away a/o December 2012. Write me for blades or the manual at either email@example.com or Bob@theaerosmith.com
More about blades:
310 tooth blades: if you're a train or model ship buff, or do some other work requiring doing really fine cutting, tiny stuff, and require a jewelery blade like the one MicroMark sells, their 310 tooth, hollow-ground, HSS blade at about $40 + tax and shipping, I might suggest an alternative. Personally, I use and recommend blades of known industrial quality. These are available, Made-in-USA no less, for a good deal less, as well as imports for slightly less, also of known high standards. A blade from a well known and respected US brand (Malco), exactly the specifications as MMs can be found here, a place I buy from for my shop often, $28.60 each:
They sell a quality import for $25.79, I'd imagine you couldn't tell the difference, but for so little difference, I wouldn't settle for anything but the very best.
December 2013: Harbor Freight now has a 24 tooth blade available. Very inexpensive. I haven't seen one yet to test-can't recommend it yet. Item #: 68400 4 Inch, 24 Tooth Carbide Tipped Saw Blade. $4.99 at the stores or on line plus shipping. Take your chances...
Replacement BELTS: You NEED to replace your belt if you're running an original type. These are seamless belts, only ones I've seen. Smooth running. The belts are only $7.50 and $2 to ship (US). I'd get two, a lifetime supply. I've sent hundreds of people here, never heard a bad word. Also has printed copies of the manual for sale in case you don't want to print your own from my free .pdf...has blades, too, but I wouldn't want you to know that.
Be sure to look here for some mind-boggling, super quality modeler's tools made by modelers for modelers:
Jim Byrnes saw fully equipped isn't cheap and it shouldn't be. It is billet
aluminum, CNC made right here in the USA by Jim. It has some extraordinary options available. It doesn't feature the standard tilting arbor a Dremel does, but an (optional-$125) tilting table that I understand isn't nearly as convenient to use; has to be mounted to the machine to make angle cuts rather than just crank over the blade. Still, a superb machine capable of super-precision work. He has some other items worth looking at, too. Neat stuff!
See the page with more photos of the saw modifications.
If you don't do anything else for your saw, get carbide blades...and buy a spare belt. I think the HF blades are a great deal, and the Zimbyo seamless belts have good feedback. Smoother running than standard belts.
Other items of interest to Dremel owners:
Harbor Freight has (had-see note below) carbide blades nearly identical to the (VERY expensive)Micro-Mark blades, but for an excellent price. William Berg Co has toothed pulleys and belts, and Grainger may have motors.
From the folks at Dremel: The correct belt for the DREMEL saw through McMaster is Catalog No. 6082K51 and you need to specify 10" circumference, 1/4" width. Check their site for this time at www.mcmaster.com.
(Those Zimbyo belts: http://zimbyoproducts.com/shop/article_ZIM-DTSB/Belt-for-Dremel-Table-Saw.html?shop_param=cid%3D2%26aid%3DZIM-DTSB%26
Also check Micro Mark that specializes in small tools and accessories. Their web site is www.micromark.com. The correct belt for the DREMEL saw through Micro Mark is #82871. They also have blades for the Dremel table saw #60293, #602994. Blades are VERY expensive, but good.
www.harborfreight.com (See note) Great quality carbide blades at an EXCELLENT price.
24 Tooth: #90175 @ 7.47
40 Tooth: #90176 @ 10.99
These are an extraordinary buy, and I highly recommend them. Only differences, aside from them being about third the price, is that they cut a slightly wider kerf.
1-28-12 NOTE: Sadly, these great blades have been discontinued by HF. BEWARE, one of the numbers has been reused and if you order it, you will receive a 7" blade!! You might try calling your local HF stores to see if they happen to have any of the little 4" blades left on their shelves. 1-13: they just got a new 22-tooth blade that's really inexpensive. I bought one and it doesn't look as good as the old 20-tooth they carried. Haven't tried it and haven't user's experiences yet. Most of us need a 40-tooth for most of our work anyway (so relieve me of a pair of the ones I have...)
Toothed belts and pulleys:
TB7UP4-120 (120 teeth) 9.99
TP7A3W4-22 3/16" bore 9.99
TP7A4W4-24 1/4" bore 10.23
TP7A4W4-30 1/4" bore 10.97
This guy has some NEAT tools!!
Here are some modifications The AeroSmith found most useful.
(See Dremel Photo Page)
1) Mounted to 3/4" Marine plywood base.
2) Table top surfaced on the milling machine.
3) Switch wired with hot pigtail for vacuum; it comes on when the machine is running.
4) Completely new, micro-adjusting rip-fence built.
5) Stock Dremel Miter highly modified for accuracy.
6) Inserts made to minimize the gap between the blade and the work.7) Backside enclosed and vacuum fitting attached for really good dust control
