1/4" Shank 45 Degree Lock Miter Router Bit - 1/2" 9/16" 3/4" Cutting Height Woodworking Glue Joint Tools Set 3Pcs by ROOCBIT

Quality

Only tried the 1/2# bit. Worked perfectly.

Well the corner joiner is big. Too big to work with ease. I'm going to have to build a special router table for it because it doesn't fit on mine. It would work fine for my makita plunge router. BUT it doesn't have a guide like the others. This would be fine if I was using a larger board that I could use my guide rails on. But I'm trying to join 2" boards. So it's been a hassle trying to figure out how I'm gonna make this cut. But besides that (which isn't their fault at all) the bit seems to have a good cut. It appears to be strong. I bored it right into a board just to see if it would bend or anything. And it didn't. So I have pretty good confidence in the strength and quality of the bit.

So to start That off I used a brand new Ryobi router table a router set every thing up got the depth right. Started test cut 1-2. Went smooth. Test cut three after adjustment. Sound changed. I stopped made sure every thing was tight an align started 4 cut errrr wwwwwwong. I shut it off quick. Went to look. The mitter bit bent halfway through cut. On grade 2 White pine is the wood I was using. I tried to contact the seller of the tools an to no avail even after amazon guy russi suggested. I a stating this but is probably possible the most dangerous router bit over ever used. Bit was very sharp but ultimately failed.

Doesn't perform well on soft woods

On the very first use of this bit, the first time it touched a soft pine board, it had a catastrophic failure. Fortunately nobody was hurt thanks to proper safety equipment and procedures but the router table was seriously damaged and requires replacement. The router itself was not damaged, at least as far as we can tell right now. The other bits in the kit have all worked well so far but with this catastrophic failure, there's no confidence that they won't explode either. Considering the cost of the router table and these bits, I'm out about $200. Very unhappy with these bits and (so far) the inability to get things "made right" by Amazon and the vendor.

Looks like it will work

I have been using routers for many years. I inserted a finger joint bit into the router tighten the bit up turn the router on and immediately the shank on the router bit Bent didn’t even get a chance to touch a piece of wood to it the other router bits work OK tried to get finger joint router bit replaced but haven’t been able to contact company
