Yakamoz 2Pcs 1/4 Shank Top and Bottom Bearing Guide Flush Trim Pattern Router Bit Set Woodworking Cutter Tool with 10 Pcs Top Mounted Replacement Bearings

I used these to route mdf using a template guide. On first use, the ball bearing literally fell apart and flew off, leave a huge gouge into my template and desired workpiece. With that said, the cutting edges are as good as most premium router bits. Paint is atrocious and flakes off. these are quite wide, so youll want to have your router set to its highest rpm (if its variable) as the bit will want to jump and skip if the router is spinning too slow.

Piece of garbage. Only used once on 3/4” oak plywood and it almost hit me in the face. Highly do not recommend.

My guitar top was over the size of the back and so I flipped it over and put this bit in my router table adn slowly worked my way around the guitar body. It did a beautiful job at replicating the wall of the back of the body on the faces edge to match. The blade isnt blunt or chipped after that job and it hardly smoked or heated going at a reasonable speed. because of the cheaper quality make sure you go with the grain or there WILL be tear out of the finer more delicate edges. tape up and do it right the first time. Thumbs up. PS. keep in mind a half inch shaft will not fit a domestic router bit hole. It has to be a quarter inch. Quicly arrived and well packed with their own little hard plastic cases, really stoked. Thank you.

The bit itself is ok. The bearings on the other hand are crap. I used this first time to trim a piece of 3/4” subfloor being used for a workbench top. Routed/trimmed about 6 ft and bottom bearing failed. No problem, they provided 10 spares. Went about 5 feet and second bearing failed. Got to within 1 foot of being done and third bearing failed and the bit cut into the work damaging it. Not a big deal as it was a workbench. Definitely would not use on a fine piece of work. At this failure rate I’ll be out of bearings in 2 more simple projects. Returning it. While cheap, not a good value and not worth risk of messing up a good piece of work.

This is the first time Ive used this kind of bit on a router table. Worked very well to cut out a body for an electric guitar using a template.

every time I used them something would break. Mostly the bearing on the top would come apart. One of them actually broke in half while in use. I ruined two templates because of them. They also are not very sharp and chop at the wood leaving ridges. I ordered some more so that I can trash these things.

These are horrible. quality, if you are roughing and edge maybe....bought them for the depth. the quality is absolute junk. do not buy

This is a brilliant idea, since it is generally the bearing that goes on these flush cut bits. I bought this, fired up the router, went a couple inches on the cut, and the screw and bearing flew off. Alright, maybe it doesnt come tight enough to use from the factory. I retrieved the pieces, put it back together, tightened it, but the same thing happened. I repeated this process, tightening the screw until the allen key skipped in the screw head. It is thus not possible to tighten the screw any tighter with the allen key. Well, the screw and bearing once again flew off after a few inches. This time I reassembled, tightened to the max with the allen key, then tightened further with my vise grips. The screw snapped off, rendering that bit unusable. Moved to the second bit, tightened to the max with the allen key until it skipped in the screw head, then gave just another 1/8 turn with the vise grips. Perfect! Fired up the router, cut a few inches, the screw and bearing flew off again. So I conclude: brilliant idea, but unfortunately does not work.

this is a cheapo. so go slow and chew less meat. best to run a variable speed controller and run it at medium speed. if you fail to listen to this then u get what you get. dont be stew pedd cheerz p.s. i would buy again if i blow this one up

Great value but dont use freehand routing it needs both bearings in contact with the work surface
