Dremel 4000 Rotary Tool - Review
"Man, this thing has some stones."
That's what our coworker said after borrowing the Dremel 4000 to fine tune a radius cut on a piece of 1/8" steel. The grinder bit was devastated after the five minute process, but the tool seemed like it was just getting warmed up.
The Dremel 4000 is simply the latest update to Dremel's omnipresent rotary tool. Over the years, we've tried a number of different rotary tools and we keep coming back to the fact that Dremel is where it's at in this category. In fact no one we know even uses the term 'rotary tool,' preferring to use 'Dremel' as the catch all, like 'Kleenex.' So with the release of this new installment in the ongoing Dremel saga, the company was nice enough to ship a unit our way for reviewing purposes. We immediately tossed it in the back of the truck and headed off to work to see what it was capable of.
So what's new with the Dremel 4000? Quite a bit actually. And as an added bonus, the changes are pretty significant when it comes to the functionality of the tool.
First, the 4000 is more powerful than its predecessors, ticking in at 1.6 amps, as opposed to the 1.15 amps of earlier models. We understand that 0.45 amps might not sound like much, but here it makes a large difference. Compared head to head with an older Dremel, the 4000 has reached a strength level that really increases the uses of the rotary tool. Until now, we saw Dremels as items that are useful in many situations, but their 'hobbyist' vibe (read: low strength) prevented us from embracing them as a job site item. Since we're coming at things from a carpenter's perspective, the added strength is right up our alley and, like we said, it opens a lot of new doors for the tool.
But there's also a 'double-edge sword' thing going on here though. Yes, the tool is more powerful, but because of this added strength, the Dremel has outgrown some of its accessories. We used the 4000 to tinker around with the pre-cut lock set openings on a metal door and while the tool showed no signs of stress, we went through the grinder accessories like they were made of origami paper. They might be fine for someone sitting in their basement carving ducks, but on a job site, a more aggressive grinder wheel is necessary. If we were Dremel, we'd start considering a 'Pro Line' of accessories. If they're going to make a tool with this strength, morons like us are going to push it well beyond its limits on a regular basis. (For all of you non-carpenters out there reading this, you can probably ignore this paragraph and take comfort in the fact that the Dremel 4000 is powerful enough to do what you ask.)
The added power is just one of the cool things about the 4000. There is also a new handle attachment called a 'detailer's grip,' that screws onto the chuck and allows a tremendous amount of control over the tool (not available in all kits). During use the handle would loosen some, but this was nothing more than a minor irritation compared to the level of added maneuverability. The kit we used also had a sanding guide and a multi-purpose cutting guide (not available in all kits).
To wrap things up, this is a fantastic tool and by far the best rotary tool in Dremel's already stellar line up. The ergonomics are off the charts and like our pal so eloquently said, it does indeed have 'stones.' Lots of 'em.
It looks like there are three kits available, the differences being in the number of included accessories and chuck attachments. We tested out the 3/34 (3 attachments, 34 accessories), and after looking at the other kits, that's probably the one we'd recommend. There is also a 2/30 kit and a mega 6/50. We suggest checking out each kit to see which one suits your needs best.
