The photos provided are leading the customer to believe that they have received both bits needed to make T-slots in wood. The reality is that only one bit is activated. Amana makes wonderful pieces. I have many of them and love them all, but this list is deceptive.
This would be a great product for the price but the picture and product description are misleading. They show and describe two T-slot cutters, but I only have a T-slot cutter, not a straight cutter. I contacted the seller (Routerbitworld) and they agreed it was misleading and promised to change the add. I had to wait another week but they sent me a straight beat. Very good quality product and works great now that I have both attachments.
After drilling a 5/16" hole in a piece of wood, I use this drill bit to widen the hole at the bottom so I can have a 1/4"-20 -Can use T-bolts to make my woodworking jigs and jigs adjustable. With this cutter (and a 5/16" straight cutter) I can cut a T-slot. No more ordering a T-track and waiting for it to arrive. Also, it's a lot cheaper to make your own. Next on my list is to buy a larger t-slot bit so I can use carriage bolts in that track.
