Just bought this bit to use on some drawers i plan on makin and I am having a heck of a time. take a look at pics below. For some reason I keep getting some form of snipe when I use the bit. The fence is even and flush with the bit. Its really frustrating . take a look at the first pic.

As you can see on the 2nd pic, I have a gap. I don’t know why? I thought I had everything set up correctly.

Does anyone have experience with this bit? I could really use some help.

Thanks, Jeff

As far as the snipe move your fence out using a feeler gauge till it is flush or slightly passed the center shank of the bit, as far as the gap is concerned using plywood could be part of the culprit, but try raising the bit first
Hope this helps :)

Source: I’ve used one of these in a shaper before, though I’ve never used one on a perpendicular joint like that, only on panel piece edges.

Because this type of bit removes material from the entire edge, the fence has to be set up like jointer tables. The outfeed face should line up with the end of the little tongue, since that’s what sticks out farthest. This is for the piece you feed flat. For the piece you’re feeding standing up on end, the fence needs to be flush, and high enough that the uncut part of the piece rides on it (above the bit).

As far as the gap, I don’t think this type of bit is intended to do this type of joint (you’ll want a drawer lock bit instead), but you might try lowering it so the shoulder in the piece in your hand is right at the thickness of the perpendicular piece.

As JJ said you need a drawer lock bit for this type of joint.
The reversible glue joint bit is more for edge gluing and not for joinery. You can also use the table saw to make drawer locking joints as well if you don’t want to buy another bit.

You may want to try a lock joint bit like this.

You might want to try to turn your pieces around (if that makes sense) rout the face of the other piece and vice versa. You need them to fit like this, right?
