Circle Cutting Jig,Circle Cutting Jig for Electric Hand Trimmer Wood Router Woodworking (C)

I have already used it to cut a few large circles out of 3/4" material, and it works very well. Very stable.I removed the existing base from my Makita router, and replaced with this one (I purchased the "C" model). It fits perfectly, and (with YouTube) is easy to figure out.I think they should add at least a single piece of paper with basic instructions, but there are so many videos on YouTube describing similar products, that the lack of documentation is actually not a real problem.I would add, from my recent experiences, something that is not mentioned in any of the videos on YouTube. When you are using this jig to cut out the circular hole, route the material on alternating sides, rather than performing the entire routing operation on a single side. First of all, you will need to adjust the cutting depth half as many times (I route about 1/8" each pass). Secondly, it will completely prevent any tear-out from the "back" face (as there is no back face when alternating sides). Finally, it will not ever damage the bench or other material below the workpiece (as the router bit will never be more than half as deep as the workpiece!!Just my two cents worth of advice. I've found a "spiral up" cutting bit to be the best. A "spiral down" bit will constantly clog the cut groove with material, and need to be vacuumed out. If you have the choice, I have found Whiteside to be the best bits, with Freud as a good second place.

I purchase the Type A BTMIEY Circle Cutting Jig since my electric router would not fit the existing mounting holes on the jig (B) or (C). When I received my Type A Jig, I found out that my router’s base plate & mounting holes were greater than the Type A BTMIEY, so I had to purchase a smaller Trim Router (Ryobi), but the Ridgit Tim Router would also work. For those who are looking to purchase the BTMIEY Circle Cutting Jig its dimension’s is 12 ¾” inch long and is 5 1/16” inch diameter where you mount your router, and its 3/8” thick.Even after all that, it was very easy to mount the trim router following the instructions that were provided with no problems. I made sure to use a wood clamp to lock down the routers base plate to the Jig, to center it before drilling the holes with a Countersink Drill Bit.I used a drill press to drill out the mounting holes but you could do using a hand-held drill.It has a max cutting Radis of 13.1889 inch

No instructions but there is a good youtube video that walks you though how to use it, search for:Router Circle Cutting Jig Easy cheap Manor WoodI got the version 'C' and it was very easy to mount my Bosch PR20EVS. After cutting a few 7 inch circles I was glad I purchased this, super easy to use and adjust. I cut the circles rotating clockwise so that the rotation was tightening the guide pin. The plastic is pretty thick, about 3/8" or 9.5mm. Also note that the bit that comes with it is a drill bit for the guide pin hole, not a router bit.

I was going to make one off of plexiglass, but after calculating costs, I decided to get this jig. I tried it minutes after package was delivered! Works great with Makita cordless router (I purchased C ver). The fact that you can make mortises by using the supplied pins - a BIG plus! (although I need to see it in action to believe it :)So why is it nearly perfect? well you cannot mount a plunge base to it, without drilling . You could probably get the ver A and do it then...Anyway, it will definitely stays with my jigs collection !BTW, instructions are included !

The tool is top quality material, I was very impressed. I got the blank style so I had to drill my own holes for my router. Nailed it the second time around, lol. Make sure to have a counter sink in order to drive the router screws flush. I would definitely recommend this tool.

Seems to work. First time using a circle jig. There were no instructions for use of the jig, which would have been helpful for a first timer, but I think I managed to figure it out for the most part after some trial and error.

Easy to adapt to my Ryobi router.

Nice idea.. very hard to set up accurately because there is no visibility underneath and no scale markings on the item but the worst part is the cheap aluminum bar that bends you tighten it to hold it in position. If making a circle cut the diameter is set by the adjustable pin in the center and to cutter rotates around that pin at set fixed distance. The adjustable bar bends when you tighten in in position raising the cutter off the surface and ruining the cut.
