CRB7 Universal Combination Router Jig MK3

    Fred P

    Money well spent
    I needed a quick and easy way to rout some mortises in table legs. This worked amazing well for this. It was my first time to do mortise and tenon joints and I tried a couple of other ways that didn’t work to my expectations. It would have been better if the CRB7 Router Base came with it.

    Good investment
    This jig was a life saver. Mortising door slabs for new installation has super easy and they came out nice. This was definitely worth my investment.

    Robert S – Rockler

    very multi-functional

    A Knowland – Woodcraft

    Quality Product – I used the CRB7 and Mortising kit to rout the dovetails on the pedestal of a Shaker candle stand table and it worked like a charm. It saved a lot of time and the joints came out perfectly. Thank you again for a quality product and for standing behind it.

    Darvin R – Rockler

    Works great – I have only used 3 times but so far so good.

    T Smith – Amazon

    Great for routing – Fits perfectly and Works very smooth

    Robert S – Rockler

    Great Product – I have used the M-Power CRB7 jig with a DeWalt DCW600 20V trim router to cut circles out of 3/4 inch plywood with great results. I like the micro adjustment feature which allows for the easy adjustment of the circle diameter to the exact size desired. I have also used the same setup to install T-track on a bench and use the edge guide to make evenly spaced dados for the next row of T-track. I highly recommend the CRB7 and find it to be great quality.

    Jessica Beatty – Amazon

    Excellent Product – I got this before the router showed up so I didn’t get to mess with it for almost a month. When I did start to get it set up I spent a good bit of time but once I got the hang of it I cut precise dados that worked out perfect on the first try. I would advise buying the edge guide with it and get a digital height/depth gauge, or setup blocks, to set the router bit height/depth. Also, if you buy a Dewalt (dw628) router it apparently doesn’t come with the required thumb screws, though everything fits together. So I had to get some metric bolts for now and order the thumb screws. The one thing I with this kit had was a storage case for all the little parts. I will come up with one, and usually I don’t like the stock cases anyway, but it this case I’m using the box it shipped in at the moment. If you are woodworking with routers this is definitely worth the investment.

    Good router attachment.

    peggy hambel – Amazon

    Fits routers great – Many uses

    Jim N – Amazon

    May not fit your router – Does this jig work? Yes, however it took me considerable time to get it to work with my router. I have a fairly large Skill unit. Interestingly it has very small passages cast into the base for the rods to pass through. I had to actually drill them out! Additionally the locks for the rods on my router are underneath so I cannot access both. I can only lock to one rod, Obviously I chose the adjustable rod. I am considering modifying the base to allow access to both rods. That aside I am so far happy. Going to cut a couple large circles later this morning.

    Useful jig – well made – Using it to remodel kitchen to cut panels from 1/4” material.

    Scott B – Via Rockler

    Excellent Product – Definitely makes numerous jobs more easy

    Jim – Via Rockler

    Works well – It works as advertised and is easy to use.

    Dutch – Via Rockler

    Best thing since sliced…. – have four Bosch routers, found their guide adequate but with short comings. took a look at this unit and it is an absolutely great upgrade. the fact that it is capable of multiple chores and is built with precision should not get in the way of it just being fun to work with. added the edge trim guide and spent the afternoon finding out what it was capable of. I’m happy as a clam.

    whr – Via Rockler

    great tool

    Dale M – Via Rockler

    nice piece of hardware – It will bring life to an old large plunge router.

    Luis O – Via Rockler

    Peter J – Via Rockler

    A very versatile accessory
    I have had mine for several years, use it for a variety of tasks. Bought one for my son in-law who’s getting into the hobby.

    Douglas B – Via Rockler

    Well made good add on – This a five accessory. I want to buy the other accessories that are available

    Gary P. – Via Amazon

    Good Idea – This has got to be one of the most useful router attachments I have ever bought. I now am able to use my router in lots of new and different ways.

    Jonathan Smith

    One can easily make a suitable jig from MSG and a few – This is quite expensive because it is well made but has quite limited use, one can easily make a suitable jig from MSG and a few screws. I thought it would hook onto my trend varijig but it doesn’t.

    Four Stars – Its Good

    Great Product – Versatile

    Mr William Cipolla Sr

    Well Made – Easy Set Up – I bought this to do mortices, dados and edges of my projects.

    William J Cipolla – Amazon

    Great addition for a router – This tool is easy to assemble and allow me to do some things that I was not able to do with my router until I got this tool. I recommend it for doing circles and doing dadoes and for doing edges of boards and plywood.

    Guest via Rockler

    Quality.. this is first and foremost.. – I have used the other plastic circle guide but this is the real deal, very well engineered and well thought out. If you do any amount of wood work this should be in your tool selection… fast accurate and worth the investment.

    David via Rockler

    Mpower Combination Router Base CRB7 – I contacted the Mpower factory direct via email and they have amazing customer support. They sent me out the 12mm rods free of charge for my Dewalt Router. I am very happy with the product now and will definitely buy from them again

    Ted via Rockler

    A well thought out and welcomed product – I’ve been a wood worker for 25 years. I have almost exclusively used a router table and table saw when routing, because I haven’t liked the stability of a router. I bought this product (along with the edging trim kit) to hopefully give me the stability I wanted and therefore, additional versatility. It did exactly that and more. Edge trimming and flush trimming are finally a breeze without the worry of “dimples”. While I do most of my mortising using a standalone mortiser (go figure), there have been times when I needed to create a mortise “after the fact” on a project. This does it easily. My favorite feature is the ability to create repetitive dados knowing that the alignment is perfect. One the main keys to good working and safety is control. This product finally does that for me when using a router by hand. It will take you a few minutes to get it set up, but once I did, I have been able to leave it attached for all of my hand-held routing needs. I recommend it highly.

    Eddie via Rockler

    Great Product – It easily allows accurate workmanship – I have modified my Combination Router Base to provide more stability between the router and the base. It felt that the base was too flimsy to take some of the pressure during cuts and had concerns of the 2 screws below cracking the plate. Also found the plate was flexing away from the router base plate. Method used was a piece of wood with 2 holes for the rods to pass through freely and it is screwed upward at Read More

    Edward via Rockler

    What a tool – I don’t know of another tool, for layout and cutting in so many ways, as this one. Any width of dados from one setup ( plywood thickness) inlay work (different patterns) and circle cuttings, just to mention a few.

    Anita M via Rockler

    Handy tool to have – This is easy to apply and easy to use.

    Ern via Rockler

    Useful – I needed something to cut mortises on the back legs of curved dining chairs I was making and it worked fantastic,

    A Rashad via Rockler

    Must have router accessory – If you need dadoes, rabbits or grooves in large work pieces this is the tool to have. Works equally well at edge routing or while doing interior work. I’ve coupled mine with my clamp-on edge guide with great success.

    TRANSLATION: I use a router from the brand Elu. The assembly was very easy without problems. Very user-friendly. Have applied different possibilities and yes it was fine. So, a must!
    ORIGINAL: Ik gebruik een Bovenfrees va het merk Elu. De montage was zeer gemakkelijk zonder problemen. Zeer gebruiksvriendelijk. Heb verschillende mogelijkheden toegepast en ja het was prima.
    Dus, een aanrader!


    TRANSLATION: Sits well and works easily. This Baseplate functions as a guide for various operations and does so for an amount that is very reasonable. Nothing to complain about. Recommended!
    (I use the device with a Dewalt D26204K)
    ORIGINAL: Zit goed in elkaar en werkt gemakkelijk. Deze voet functioneerd als geleider voor diverse bewerkingen en doet dat voor een bedrag dat heel redelijk is. Niks op aan te merken. Aanrader!
    (ik gebruik het apparaat met een Dewalt D26204K)


    TRANSLATION: Nice addition for the Maschine cutter. Only when you use a Festool 1400, like me, the fine adjust can NOT be used as Festool is locked on two 2 axes with one button.
    ORIGINAL: Mooie aanvulling voor de frees maschine. Alleen wanneer je een Festool 1400 gebruikt, zoals ik, is de fine adjust NIET te gebruiken daar Festool met één knop aangedraaid wordt op de 2 assen.


    Translation: The CBR7 is the perfect solution for circles. Both for small circles in speakers. As for a table top.
    Or the copy function to mill multiple grooves is excellent. It is worth the investment.
    Original: De CBR7 is de perfecte oplossing voor cirkels. Zowel voor kleine cirkels in luidsprekers . Als voor een tafelblad. Of de kopiëer funcntie om meerdere groeven te frezen is uitmuntend. Het is de investering waard.

    Perfect circle jig – Makes it very easy to cut small diameter circles with a router.

    D Smith – Amazon

    Works Great – I’ve only used this jig for cutting arcs and circles, but it is simple, sturdy, and very accurate.

    Calvin Moldenhauer – Amazon

    Nicely built works okay

    Westerner – Amazon

    A Quality Tool – I use this primarily for making circles, but it can be used as an edge guide also. I like that the router is positioned by the rails and not with the myriad bolt patterns for different makes’ sub-bases. I wish the micro-adjustment device worked a little smoother and easier, but overall this tool has worked well and I can see it has more uses I have yet to employ.


    You spin me round – Bang On – This is not like the photo and I don’t care. Easy set up, not getting why some cannot centre their routers, my porter cable, dewalt, and ryobi Were a breeze. I love that you can “creep up” on your cut diameters, and make ANY small adjustments necessary. Well worth the price difference for a circle jig. Buy this, it’ll destress Your circle cutting.

    Easy set up, easy to use. Real pleasure how simple this is to set up and adjust. Versatile, fast, steady for round and straight cuts. Don’t understand concerns regarding smaller rods than before: they still tighten in all 3 routers I own, and if you push your cuts hard enough to bend them, you’re probably snapping your bits. Learn to use tools! Highly recommended product.


    Top notch engineering – I haven’t had a chance to use every feature this is has. There are so many ways to use this simple yet elegant piece of equipment, it will be some time before all are tried out. Fit and finish are great and the functions I have tried were easy to set up and came out perfectly. I do high-end fine woodworking as well as speaker building, and this tool accessory is a jewel for the price of a rock! I recommend the edging kit if you work with plywood part #365-652 See review.


    First Day – I used the M.POWER CRB7 for the first time today for a dual 6 ½”woofer, soft dome tweeter build. I was using my Dewalt DW618PK. I wasn’t able to use the handle that comes with the CRB7 for most of my cuts because of the Dewalt handles interfering.
    I ended up making a small adapter to keep my cuts accurate. The posts that mount to the plunger section of my Dewalt are smaller in diameter and caused play in router to CRB7 mounting. It would be a lot nicer if there were sleeves to make it a tight fit. My adapter did not work for all cut diameters I needed.
    The CRB7 is a lot nicer and easier to use then a similar kit that I bought from sears.

    John Frum

    Great Circle Jig – I love this tool. I use a digital micrometer to set the diamter and knock out perfect circles. It’s as accurate as you can measure. You are not locked into 1/16th of an inch increments. Oh and it does a bunch of other stuff I have not tried yet.

    Chris C – Infinity Cutting Tools

    Great Product – “only played with it on scrap however it is built well and I can see many hours of use I would recommend it”

    Stephen K via Rockler

    Functionality – Adds a lot of functionality to my small DeWalt Router.

    Greg Hines – Middle Tenesee

    I like it! – I have had this for a couple of years, and while I do not do as much woodworking as I used to, it is particularly versatile when you need to use a router for many common hand held procedures. I have used it for edge banding, dados and grooves, and a couple of circle cuts over the years.
    My only complaint is not really with the base, but with the Porter-Cable 690 router that I use with it. I use a plunge base, and it is very handy. However, the PC690 uses regular Phillips head screws to lock the router to the guide rails, and nobody sells thumbscrews in the 12-24 pitch that you need to replace them. Nobody, that is, except for Who will be happy to sell you between 800 and 4000 of them. Why that would be is a very good question.

    King Waters – Via Hartville Tools

    One nice thing.. – This jig takes a little getting used to [what doesn’t?], but it works. I suggest you take a little care with it. My son used it as a circle cutter and succeeded on his first try. One nice thing is that it gives you a way to see exactly where your adjustments take the bit, before a cut is ever made. The base is plastic, as is the edge-guide. So don’t toss it around. It is from a British company, and they have thought out various operations. Videos are available on their website, and on YouTube. Buy it on sale, or with credit card/Amazon points, and you will be getting a useful piece of equipment. I also have a Micro Fence, which is more expensive, but more robust. I use whichever makes the job easy and efficient.


    First Impression – Good item, good quality, start to test it.

    Thanelson – via Madisound

    Quality first and foremost – I have used the other plastic circle guide but this is the real deal very well engineered and well thought out. if you build speakers or do any amount of wood work this should be in your tool selection before you buy more bits fast accurate and worth the investment.
