Last month I posted about the new Veritas rotary tool plunger base, and as some of you pointed out, this wasn’t the first attachment that turns a rotary tool into a router.
Here are 4 more rotary tool attachment options that we learned about thanks to reader comments and some more research. Prices range from very affordable to almost absurd.
Dremel 335-01 Attachment
The cheapest option is Dremel’s own 335-01 plunge router attachment. This attachment mounts to your rotary tool via it’s threaded housing.
This attachment features a clear base to make it easier to view your workpiece, two depth stops so you can make progressively deeper cuts, and storage for the wrenches and extra bits on board.
Dremel says this attachment is compatible with the 100, 200, 275, 285, 300, 395, 398, 400, 3000, 4000, 8200, 8220, and the 4200 with the 4200 attachment adapter, but it probably works with other tools, as long as it has the same threads as the above Dremel tools (3/4-12).
The Dremel 335-01 plunge router attachment comes with an edge guide for routing parallel to the edge, a circle cutting guide for making arcs and circles, and a mounting wrench. You can buy it at Amazon for $20 with Prime Shipping.

Milescraft 1000 Plunger
Thread the front collar of your rotary tool into the Milescraft 1000 Plunger, and you’ll turn it into a small plunge router with integrated dust collection.
The plunging mechanism is designed with three steel posts for sturdier construction, rather than the normal two, and the clear base is also compatible with Milescraft’s TurnLock inserts.
If you look at the instructions, the plunge mechanism works a little strangely. You zero the bit like normal and set the depth gauge to the desired depth. But then instead of puling a release lever, you just push down on the handles to plunge the bit into the workpiece and the height will lock at the last position. When you want to release the plunge mechanism and raise the bit, you press the lock tab on the right handle.
According to the Amazon page, the Plunger base can be used with Dremel models 275, 285, 395, 398, and 8000-01; ToolShop; Mastercraft; Craftsman; and Black & Decker RTX, but other rotary tools should work as long as they have standard Dremel threads.
The Milescraft 1000 Plunger base comes with a steel edge guide and a circle cutting guide. Home Depot says this base has been discontinued and I can’t find it on the Milescraft website, but it continues to be sold at Amazon for about $25 shipped with Prime

Stewart MacDonald Base
As Chris Parker pointed out in the post where Stuart discussed his ordering of this plunge base set, StewMac also makes a precision router base. It’s much simpler design, but maybe that’s what you’re looking for.
Stewart MacDonald says their compact base, is the best way to hold a Dremel for freehand routing, inlaying, widening fret slots, and more. This base was designed especially for working on stringed instruments. They tout their base as having easy installation, excellent control, accurate freehand routing, all while being sturdy, compact and adjustable.
They machine the base from steel, brass and aluminum. The depth is adjusted with large thumb wheels and each complete revolution adjusts the depth by 0.035″. The plunging mechanism also doubles as handles to give you more control of the base.
The base has a built-in nozzle which can be attached to a mini-air pump, allowing you to blow dust away from the base for better visibility.
Installation for this base is the same as the others, the threaded plastic nose of your rotary tool screws right into the 3/4-12 threads of the base.
You can buy just the router base on the Stewart MacDonald site for $55 or you can buy a set including the rotary tool base, an edge guide, a 5/16″ router bit, and an air pump with hose for $110. The edge guide and router bit selection are intended for guitar-making applications, so they might not be suitable for other types of work.
A very similar looking tool is also available on Amazon. It’s unclear as to whether it’s the same model or a clone.
Micro Fence Base
On the high end of the price scale, Micro Fence sells a very expensive plunge base and edge guide for rotary tools. But for your $500, you’ll get adjustable precision to 0.001″ in both the horizontal and vertical axes.
Lets step back a moment, before fixating on the high price. The micro plunge base alone has some interesting features. This 4″ diameter base has “silky smooth” plunge action, it has a very open design that allows for high visibility when making cuts, and there’s a micrometer dial for adjusting the cutting depth with high precision.
This base doesn’t attach to the threads on the nose of the rotary tool like the other bases, instead it uses a acrylic insert that is custom cut to each different motor. These include most Dremel rotary tools, the Milwaukee M12 rotary tool, and select Foredom, PowerCrafter, and Proxxon handpieces and rotary tools.
Made to precise standards from aluminum and hard chrome plated stainless steel, this base alone costs $300. When you buy the base, you get the acrylic motor insert for your particular tool and an LED light source.

If you want the 0.001″ precision on two axes, you’ll need to plunk down a total of $500 to get the micro plunge base with edge guide. I can’t find anywhere on the website where they mention it, but it looks like the edge guide sports another micrometer dial to get the 0.001″ precision on the horizontal axis.
At 3.5 pounds, this base with the edge guide practically weighs as much as a small router.

Veritas Rotary Tool Plunge Base
There is also of course the Veritas rotary tool plunge base that we previously wrote about. It’s $85 for just the base, and $169 for the complete set with all of the shown accessories.
