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

Works as expects, and a great value for the price. I use them on smaller drill press and haven’t experienced any issues thus far. If that changes, I will update my review.

Bits came as described and work as they should

I usually buy CMT, Whiteside, of Freud. When I would break a big name bit after less than 40 holes the cost was too much to sustain for my product. I bought this 3 pack specifically for the 3/8” keyhole bit and it has made over 400 holes and counting! I sharpened it this morning with a credit card file and it’s like new again. Unbelievable!

I have used these for cnc sign making and have not had any issues with them.

These were good quality and did a fine job of cutting key-hole slots in poplar. This size was very difficult to find when I was shopping.

Nothing special

Muy buena calidad la recomiendo

They do not come with the sizes engraved in them, but I can tell the difference! Only down side was that, they work great and do what they are supposed too, one other thing is I don’t know why they skipped 7/16 but good bits price is well worth what they do!
