Yonico Top Bearing Slot Cutter Router Bit (1/4 Height - 1/4 Depth - 1/4 Shank)

Im resurfacing my deck with Trex Transcend. Some of the boards are the square edge variety so they have a clean look on one side, but on the other side I need/want the groove for the spacer. In another case, I needed to rip two adjacent boards so as to fit in the available space. There too I needed/wanted to put the groove so that I could use spacers. I read other reviews about this product and concluded that this was better than the Trex branded router bit. The first time I used it, I thought something was wrong because I didnt feel any drag as I was making the cut. I assumed I had completely missed the board and was getting ready to reset the depth. Then I saw that I had a nice clean groove in my board. You do have to experiment a bit when setting the depth. Initially I assumed that I would want the groove in the middle of the board, equidistant from both edges. It turns out, this groove is a little slimmer than the groove on the grooved boards, so you should test fit a scrap before cutting a grove on your installed piece. I would agree with other reviews that claim this bit is better than the Trex bit. Also, this bit is very sharp and seems to be very durable. It has certainly been easy to put a nice clean groove in my decking.

Worked great

Purchased to use when retro-fitting windows. Does the job really well. Have not had any problems with this item.

I got this to cut the groove in my composite decking, and it worked out better than the one that was supposedly for composite decking, and it was a fraction of the cost.

For a small and single project I did not wanted to buy something expensive. This came pretty cheap and did the job well. Cuts were sharp and with a bit of adjustments I managed to align them properly for what a Trex deck board needs. Very satisfied with the piece. Probably won’t be using it for a long time but when I’ll need it it’s gonna be handy.

And way cheaper than their bits.

Worked perfectly for grooving the “picture frame” Trex composite deck boards. (They are not grooved) Best to set your router depth by using the groove in a factory grooved board. Easy and smooth cutting. Great value considering the much higher price for the Trex brand cutter. Highly recommend!

If you are a DIY homeowner installing a Trex deck, dont bother with the expensive Trex bit. This one works perfectly. Its very sharp and cuts into Trex boards like a hot knife through butter. Makes a lot of chips though, so have a plan to clean those up so they dont pollute the environment.

needed this to put a groove in hallway flooring at doorway as we did the hall a few years ago - cut groove for perpendicular strip at doorway - worked great as needed something that wouldnt damage the existing flooring and not have the bearing/nut on the bottom to get into the subfloor

Used this to route some trex deck boards. Wasn’t sure if it would work but it’s the same as the Trex bit but a 1/4 of the price or less. Worth the money.
