Will Leigh D4 Dovetail bits work in an Incra set up?

[CutsTwice]

Hi guys,
I just got a deal on a Leigh D4 13 piece dovetail bit set to use with my Incra Wonderfence. I just noticed that the Leigh's are all 8, 10, 14, and 18 degree bits, and it doesn't say if they are through or blind dovetail bits.

The Incra Whiteside set is seven degrees. Will my Leighs work? How do you tell if they are through or blind bits? Is there a difference?

I don't know much about all this yet, but I've just about collected all the parts I need to get started playing with them. If it turns out that these won't work for my Incra set up, I'd sell them to buy an Incra Whiteside set.

Thanks for the help guys,
J.

You didn't state if you have the LS system or just the Wonderfence.
The Incra LS System is definitely able to use Leigh dovetail bits(WoodRat bits also) Incra's system is not independent on particular bits as many other stationary jig- type systems are.
Do your bits match the sliding scales?*Metric/Imp.*
Get yourself the Incra DVD If you don't have it.

Leigh's system can only use 8° Bits for blind DTs, for example.
I've the Whiteside Incra DT set also, in 1/2", and the Whiteside 8 pc 600 set for Hingecrafter.
Leigh's bits are made in Taiwan, but the carbide is from Sandvik. No complaints so far, I've got 15 or so of them. I prefer them to the Whitesides.
