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

Worked great on hardwood floor installation. Cut 20 feet of groove quickly and accurately.

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.

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

I needed to do hardwood floor repair and this bit allowed me to add the groove I needed to the end of existing floor boards while they were still in place. Worked great!

Worked great

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.

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.

Fast shipping, item exactly as described

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!

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