Yonico Router Bits Slotting Cutter 1/16-Inch 1/4-Inch Shank 12101q

Poor quality

Using cutter for rail and stile dado cuts for raised panel doors

I needed to cut a dado around a 19 x 36” piece of Baltic Burch. Turned my Bosch corded router down to about 1/3 speed, and tried to make 2 shallow passes as opposed to one deep one. It accomplished 50% of the job with no problem. Barely made it through the last half. Was ready for the trash when finished. World have bought a Diablo, but figured I would never need to perform this application again, and for 1/3 the price,…

Reasonable price - used to groove composite decking for clips - made two passes

Great product and very strong

Better than expected thank you very much

Worked as advertised

In my opinion, Yonico makes quality router bits. This one is tricky because 1/16 is such a narrow cut. Its really just a horizontal saw blade. I bought this to install vinyl T-moulding edging in a custom melamine sewing table top. First thing to know is you dont need to make the full depth cut in one pass. Three passes or more works best in my experience. Doing it in one pass builds up WAY too much heat and youll ruin the bit in no time. The cutting teeth are so narrow at 1/16 that the metal disk is almost as thick. I actually wire-brushed the pretty yellow paint off to reduce friction-produced heat. This seems to help, but multiple passes still recommended for a full depth cut. [Edit] In the process of learning the above, I pretty much had ready heat-damaged the bit, making the carrier disk brittle (photo). Working on my second project, one of the teeth snapped off. Cant blame that on mfr. as I clearly mistreated the bit. Ive ordered another and will be more careful this time.

Bearing shaft is not standard diameter, so adjusting depth of cut is almost impossible without using a fence (ie, using bearing only.) Otherwise, decent value for the money.

Mine warped after one use.
