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

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.

Worked great

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.

This bit is great for adding grooves to cut off ends for hardood floring- best ever

After hanging really nice, Hunter Douglas motor driven faux wood blinds in the wall of windows in our family room, I discovered that having to remove these extremely heavy blinds periodically to replace the eight AA cells in their battery packs was a royal pain. Three of them are hung about 16 feet off the floor, which made removal without two people and two extension ladders virtually impossible. So what does this have to do with a router bit? Well, I decided it was time to run wires and power these window coverings from a single accessible power supply, and this is the hard-to-find router bit that allowed me to do it! I needed a bit that would cut a 5/32 wide slot in the top piece of the wood casing of each window, and I didnt want it to be more than 3/8 deep. All I needed was to be able to recess a pair of wires into the casing which would be hidden by the header of each of the blinds. Most bits of this type have a small bearing and are a larger diameter cutter, which means a deep slot. Yes I could have fitted something temporarily to run the bearing on, but it was tough enough balancing the router over raised panel trim. In fact, I had another 1/4 shank bit with a top bearing that was a larger diameter, so I put it on this bit and reduced the cutting depth a little more. Aside from being a nice small diameter for shallower cuts, the bit cuts cleanly. From the description image it appeared to have only two cutting surfaces; in fact it has three. So assuming the carbide is decent, it should make nice clean cuts for a while before dulling. For the price, its disposable. If this thing makes the kind of cut you need, buy it.

I would say this is the 2nd most important tool. Any time you rip a board this router bit puts the groove back in the board. If use use square edge boards for a professional look. This bit is needed for the inside to cut a groove. Easy to use router bit. Professional look that maintains the hidden fasteners pattern going.

Fast shipping, item exactly as described

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.

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

I used this to cut slots in Trex decking to accept their hidden fasteners. Worked perfectly and cost a fraction of the price Trex asks for their proprietary version.
