YONICO Router Bits Set Cabinet Door Rail and Stile Raised Panel Back Cutter 3 Bit Bevel 1/2-Inch Shank 12349

Ordered the Scoop set, and Og, I paired them with my Porter cable 7518 variable speed router, at around 12k rpm speed, mowed right through mdf, I also tried out some soft maple, I elevated the rpm’s to 19k and cut as smooth as a 5hp heavy duty shaper.I highly recommend these, just make sure you get the 1/2” shank, you can’t run that much metal on a 1/4” shank it could be dangerous, idk know why they offer it in 1/4”, also you need a heavy duty router that puts out at least 15k rpm, as well as a nice router table, with a vacuum, !!!!you need a vacuum!!!! It’s a must.

Quality bits - but take the time to adjust them first. The attached photo shows a closeup of my first door. My later ones were better; in particular I got better at avoiding chipping along the panel slot, and doing a better job of sanding before assembling the door. I really like the profile, although I think I would like a smooth curve up to the panel surface.Adjust adjust adjust!Don't assume that the matching smaller bits (for stiles and rails) are properly adjusted when they arrive. I made this mistake and as a result my first few attempts wouldn't fit together properly - the notch was smaller than the tongue going into it, so I couldn't get the stile to fit fully into the rail, and I had to toss my first batch of door parts.However, a simple bit of work with rearranging a few shim washers (installed between the bit parts) fixed the problem neatly, and the rest of the project went great.The panel bit is scary huge, and howls when spinning at full speed. I had to add a 1/4" plywood surface to my small router table, because the bit had to sit slightly below the main surface, to get the proper depth. I set things up for multiple increasing depth passes to limit how far I was cutting on each pass; this was necessary to work with the power limits of my router.I think the largest bit was slightly, slightly off-balance, but that's not surprising with something this large. Working with a small router table means that any slight imbalance results in a lot of poorly-damped vibration when at full speed - I assume a professional router table wouldn't have this problem, so I don't consider it worthy of dropping a star rating.I had not built cabinet doors for about 30 years - since working in a cabinet shop as a teenager. So this door-building project was really intimidating, and I was very worried about my ability to pull it off. But these bits, coupled with an appropriately powerful router, did the trick neatly. And after a few doors, I was back in the groove, remembering some of those tricks I used to use.I would definitely buy this again - in fact, I liked it enough that when I needed to buy another bit for the door edge profile, I really wanted to find another Yonico.

I rarely write reviews but I feel this needs to be said. I almost didn't buy these because of some of the reviews. I finally took a chance on them as I didn't want to spend $$$$ on Freud bits that I'll only use 1 or 2 times. I'm glad I did as the bits worked as well as I could have even hoped for.Buy these bits if you have the following four things:1. A router with 1/2" collet. These are big bits and you need the stability of 1/2" shanks. Yonico could avoid many bad reviews by not offering such large bits with 1/4" shanks, it's a recipe for failure. Even with a 1/2" collet, make sure that the shank is inserted deep....it's important!2. Router table. You cannot cut rails and stiles accurately with a hand held router....no how no way (and it's dangerous too).3. Router speed control. Slow the bit down and practice a few cuts to get your feed rate and speed right before making your panels.4. Basic woodworking abilities. If you haven't done any woodworking, starting off with raised panels is a rough way to go. It can be done but probably won't yield primo results. If you chose to do them with no experience and it goes bad, don't leave a poor review. It's your fault!I hope this helps some people decide. They are a great bit for the occasional user if you use them properly.Check out the photos. Those are the actual cuts with no filler.Paul
