5pcs T-Slot Cutter Router Bit 1/4 Inch Shank Keyhole Router Bit Set with 1/4 & 5/16 & 3/8 & 1/2 & 9/16 Inch Blade Diameter for Wood Hex Bolt T-Track Slotting Wood Milling Cutter

Although it is not an expensive product, the value leaves much to be desired. Sadly, I bought the set because I needed one of the bits and figured why not get a whole set? Why not, the one I needed broke on the first use, right the gate. I had to make due with the next size bit and an alteration to the bolt head. Not sure if I will send them back or not, but buy these if you can use either of them for your task, not if you really need them all.

Burn out city. These bits are worse than cheap, they are junk. Don’t waste your hard earned cash. There is also no way to contact anyone about the poor quality of this garbage.

I made 4 acceptable holes with the 5/16 bit and then the head snapped off during the 5th. It was hard maple wood, but I expected a little more use out of the bits than 4 holes.

Got these to make keyhole slots. Getting five sizes at this price is a great deal. Only used 3/8 so far but it made perfect clean keyhole slots. Used on pine and maple so far. Worked great on both woods.

On the very first use they snapped in half. I can't tell what they are made of but it's not for woodworking.They are garbage.
