Leigh D4 Dovetail Jig Bit Question

Any bit with the proper profile will work. The Leigh bits are excellent quality, and one plus is that you get an option for 8mm shanks, which are sturdier than the 1/4”.

LeeValley sells off brand bits for the jig as well including 8mm shanks.

I’m not even sure I have any Leigh bits. I’ve used Freud, CMT, and Jesada with mine and all have worked fine.

Rumor has it Whiteside makes many of the Leigh bits, but either way the Leigh bits are quality.

I use a mix of brands, as long as the length/angle are proper you are good (I’ll admit that it can be tricky to find some off-brand versions of those smaller bits)

Yea there are some funky sizes. Especially for half blind. And many of them are out of stock…

Is the 8 in the cutter number referring to 8mm? I know there are No. 80 and No. 80-8.

Yep.

I’d definitely go with Whiteside bits. I’m pretty sure they’ve set just for Leigh jigs. They are my favorite bits out there. I don’t buy anything else.
