About a year ago I bought an inexpensive dremel-type tool from a tool outlet. It never really worked and soon quit altogether so I worried about buying another one that was not a genuine Dremel. But I took a chance on the B&D name. It used to mean quality but lately the story has changed. Well this little gem may change my mind. In the first few minutes of use, it has ripped through some projects and seems to be completely up to the task. A really nice surprise for half the price of the cheapest Dremel. For the price you can't beat it.

And though it says three speed those are only the "stops" on the speed adjustment; my experience is that it is adjustable between those. The quick tool change seems to work fine although that may be the weak link. The plastic catch seems cheap so I'll need to watch how rough I handle it.This is a very nice tool that can do almost anything. It is also just as good as a Dremel because I once had one of those. For 1/4 the price as well it's a steal. It also has a nice lock/unlock function that the dremel didn't for safety when changing bits. I have to remember to use that though when I am using the flex shaft. But this tool does a very nice job at finishing off wood. Hollowing out wood takes some time, but I think I need thicker cutters for that than the ones I have. The stuff that comes in this kit is a carrying pouch, the tool, 2 coarse sandpaper drums, 3 finer sandpaper drums, and the handy wrench tool. It has 3 speeds, low, medium, and high. For cutting I was advised to use medium to avoid burn out and it functions just as well as high. For engraving though high is much better. I highly advise checking this one out before spending the money on the overpriced Dremel. Just as good if not better a tool than that one. You don't get many accessories with this one, but I bought a kit that had almost everything and then some for less than $20 on Amazon.com. Go pick one up today!

veryone's right, the stock collet and collet nut are garbage. Replace them. I wanted to see what others were talking about so I didn't buy a replacement right away. Immediately after unpackaging it was hard to even insert a bit because the collet lip was so sharp. After I got a bit in and used it for a while it was difficult to get the bit out. I found that I had to pretty much unscrew the collet nut completely every time I wanted to change bits. I'd get a Dremel 4485 Quick Change Collet Nut Kit with this and forget about it.

The bad:
I read a lot of reviews saying it was quiet which sounded nice. It is... when on the low setting. After you get past low an appreciable amount it jumps up in speed and gets loud. On the high setting it's actually annoyingly loud. I have a WEN 2305 Rotary Tool Kit with Flex Shaft that I got off eBay for cheeaaappp and it's actually quieter if the housing screws are perfectly tight to keep vibrations down. No matter how hard you grip the Black & Decker it's going to buzz like mad.

The good:
It's quite a bit more powerful than the Wen rotary I have. Even on the low setting it's surprising what kinds of jobs I can get away with doing. It's pretty cheap.

Bottom line:
I'd recommend this for some one who's going to get quite a bit of heavy use out of their rotary tool. I've gotten by just fine with my Wen for a number of years and the only reason I "replaced" it was because I thought the motor brushes died on me. The Wen uses a real funky sized motor brush that's hard to source and the company doesn't supply replacements so don't even ask them. After opening the Wen the problem was just that the PCB for the variable speed pot had gotten fried somehow and had a lifted/open trace. Resoldering this with a jumper wire completely fixed the problem and it's back in action. The Wen is more than capable for most jobs I find. My only gripes with it are that I have to crank the speed a bit to get proper torque and that it doesn't accept Rockworth RW1504ST 4-Gallon Hitachi KM12VC 11DEWALT DW368K QEP 83200 Hitachi G12SE2Surebonder 9772 Bosch PS10-2A 12-Volt Stanley Bostitch PN100K LCON40 40 DEWALT D28114Powerhouse XM-380 7-TonDEWALT DCG412B 20-VoltPaslode T250A 16-GaugeHitachi NV45AB2 JET 629004K 16-32 DEWALT D25023K Rikon 50-150 Belt/Disc Dremel 3000-1/24 1 Attachment/24Milwaukee 2310 12-VoltMakita JN1601 5

I used to buy Dremel tools fairly frequently. They were very useful, but they didn't hold up well. To be fair, they were fairly heavily abused. But they would break pretty easily, and I got tired of fixing them and replacing them... The brushes would get hot and melt the brush holders, the electronics for the variable speed would fail, etc, etc, etc. I would spend $80 a couple times a year buying Dremel tools.

I bought this as a replacement for the Dremel about 8 years ago, and I use the heck out of it... (All the abuse that I put the Dremels through I heap on this tool... And more!) The only reason I bought it was I had killed my second Dremel in less than a year, and I was tired of spending the money! This thing was so cheap I thought, what the heck, I'll give it a try.

The difference is, this $30 tool has never quit! It still works like new, and I beat the tar out of this tool! I reach for it several times a month, and it just keeps going! I have gone through hundreds of cut off disks, hundreds of sanding drums... It has way more power than a Dremel, and the 3 speeds are exactly what I need.

Everything about this tool is better. The flip up lock, the on-off switch, everything! It's a work horse that you just can't kill.

The RTX-B is 100 times more durable than a Dremel, it's more powerful than a Dremel, and I like the controls better than the Dremel. If mine got lost or stolen, and I had to replace it (because that's much more likely than having it quit working...) and Dremels were on sale for 2 for $5, I would still buy this tool.Makita MAC5200 DEWALT DWE575 GenTran RJB10410 10-Foot 30Panasonic EY7410LA2S 3.6-Volt Bosch DDB180-02 18-Volt PacTool International SS404 DEWALT DCD970KL 18-VoltIngersoll Rand 121K6AIRCAT 6255 Bare-Tool Makita BHP454Z 18-VoltDEWALT DCK210S2 12-VoltDustless Technologies MU305 Shop-Vac 9625510 6.5-Peak Fein FMM 250QDEWALT Bare-Tool DC608B 18-Volt MR-50 SteamPorter-Cable PCL212IDC-2 12-Volt Rockwell RK5108KDEWALT DW331K 6.5Makita GD0800C

I purchased the RTX-B intending to use it as the cutting element on a light-duty CNC mill I built, as well as for general handheld use. While the motor power holds up under load, I was disappointed to find that the shaft wobbles excessively while spinning. Even with the tool turned off, light finger pressure against the collet would cause the end of the bit to deflect visibly. For drilling and milling tasks, this shaft wobble resulted in uneven cuts with a larger diameter than the bit itself, as the bit is not so much spinning as orbiting within the work piece. For hand grinding or cutoff wheel use, it resulted in excessive "chatter" against the work piece in some orientations.

Since I'd already invested the time building a mount for the tool, I decided to take it apart rather than try for a refund. The problem stems from the way the collet shaft is attached to the motor internally. Rather than a rigid coupling, the motor and shaft are coupled via what is essentially a universal joint. In addition, the motor itself is mounted on rubber vibration dampening pads, and so itself can move about inside the case when load is applied. Together, these factors cause the shaft end to wobble all over the place.

If you have already bought this tool and experience the same problem, it is "fixable" if you can get inside (the tool is held together by a mix of Phillips and security "star" screws). Running a generous portion of JB Weld into the U-joint, front bearing mount and around the rubber motor mounts seems to have cleared it up for me.Makita Bare-Tool BSS610Z 18-Volt Porter-Cable 330DEWALT DCF895L2 20-VoltBosch GTS1031 DEWALT Bare-Tool DC823B Makita 4329K 3.9 DEWALT DCK955X 18-Volt DEWALT DC750KA 9.6-Volt Bosch 1617EVS 2-1/4 HP Bare-Tool Milwaukee 2650-20 M18 18-Volt Porter-Cable PCL418C-2 18-Volt Makita Bare-Tool BSS610Z 18-VoltShop-Vac 1032000 Porter-Cable 7518 DEWALT DCK274L 18-VoltMilwaukee 2426-20 M12Bosch PS60B 12V Bosch MX30EK-33 Porter-Cable 7800 4.7 Fein FMM 250Q
