Yonico Chamfer Router Bits Bevel Edge Forming 30 Degree 1/4-Inch Shank 13905q

I've seem some reviews that have been critical of this product so I took a little time to trial and make myself familiar with the router bit before cutting on my final project. With regard to the concentricity of the top bearing I found the run-out to be .022" (Bearing to shank), this is more than I would expect but the bearing itself is true. (with this cutter I used my table fence and not the bearing for guidance.) I measured run-out at the large diameter of the cutter and found it within .004". This is a large diameter and heavy cutter so I use a variable speed router and run the RPM's at the lowest setting. With any routing I do I'll make cuts no deeper than 1/8 per pass. My cut's were very smooth and no chatter of the wood surface is evident. This a value purchase and considering the cost less than 1/2 of the top brands I am pleased that I made this purchase.

Part of this is my fault, and part of this is a stupid product. I got this to make a 45º chamfer on a 3/4" board. 4 out of 5 of the bits have a 1" cutter height. The ONLY bit in the box, the 45º, has a 23/32" cutter depth. that's .72, not .75. So, you cannot make that cut.Why on Earth anyone would make a router bit set with 4 of 5 at 1" and the other at 23/32" -- I don't effing know.The other 4 look great.... so, if you're NOT looking to make a 45º cut, this is the product for you. Well made otherwise.

Used with a Dewalt 12 amp router mounted in a table. Routed 1/4” walnut to make a fly rod case. Bit performed well and didn’t tear anything out and the seams were flawless. Used it to make about 10 cases now and am glad I made the purchase.

The overall Quality seems to be good EXCEPT the casting extends beyond the cutter edges. One dares not grind off the casting as the cutter would no longer be balanced which would render the tool DANGEROUS, yet the casting prevents the work from reaching the cutting edge without first bumping into the casting thereby deflecting the work away from the fence. I am new to this type of cutter so maybe there is something I do not know. I will try to take down part of the edge first on the table saw but am still not sure if this will work still this requires an extra step. I may modify this criticism if I discover anything about it.

Perfect for beveling the edges of 3/4 plywood to make the diagonal shelves for our wine storage rack. I have purchased several different Yonico bits, with the only problem ordering them from Amazon instead of going directly to PrecisionBits to buy them. Somehow Amazon labels different bits than what you order with a label for what you order and ships it out, requiring several returns on my part. This is the case when purchasing from PrecisionBits, via their Amazon storefront. PrecisionBits is painfully aware of this and has no idea why Amazon does this. Go directly to the PrecisionBits website and order what you want - same price, free shipping - and you get what you actually ordered.

I have not used these yet. But I purchased them specifically because the 22.5 and 30 degree are advertised with 1" cutter heights where most other options are less.Unfortunately the 30 degree' chamfer does not extend all the way to the large diameter, so you cannot get a full 1" high chamfer. (see first picture)The 22.5" degree is a full 1" high cutter, but the smaller diameter of the cutter (near the bearing) has a smaller diameter than the bearing. So you cannot take full advantage of the cutter height without an undersized template. Very strange, never seen this before on a chamfer. (see second picture)

I bought this bit specifically for putting a bevel detail on the tops of a three piece bedroom set I was building. I am completely pleased. It made excellent quality clean cuts without burning even across the grain. A CMT or Freud bit can easily run you over $70. For a fraction of the price these bits do just as well. I would definitely recommend them.

The bit is not true, I never even tried to use it, it was visibly wobbly (enough to shake the router a little). Maybe 2mm runout at the bearing. Confirmed that my router was fine. Even just holding the bit by the bearing and spinning with my fingers I could see it wasn't true. I'm returning for a refund, don't waste your time. Now I need to get another (name-brand) bit, no project progress this weekend.

The item seemed good, but unfortunately was too large for my Bosch 1200 so had to return it. The Bosch can only take up to about 45mm dia and this was larger. Yonico seems to produce good bits at reasonable prices, so bought a similar bit but of a smaller diameter. Seemed good, but double check your router can accommodate the large bit.

This make was always a long time to be delivered in this country. I first saw this make on an American channel, however they are now available here at a very reasonable price & delivery time, will be buying more of these in the future.

Good value and accurate. Has stayed very sharp over lots of jobs.

Prompt delivery, arrived in good condition, does what it says on the tin .. good value tool for DIY

Provides a very clean cut. Differently to be recommended.
