Is there an easy guide to the markings on your bits to the markings on the leigh bits
Are your bits for the Leigh DR4 made exactly to Leigh’s specifications? In particular, is the carbide height a little longer that the “cutting depth”? I’m asking because several other brands that claim to be Leigh jig compatible are not; the carbide is exactly the cutting depth (or even less!) which leaves no room for fine tuning the joint fit. For example, I recently tried using a Whiteside bit that is supposed to be the equivalent of the Leigh 128-8 which has a "cutting depth" of 3/8”. However, the carbide is actually only 0.368” (measured with calipers) whereas the authentic Leigh bit carbide is close to 0.40”. The optimum depth of cut was around 0.385” so the Whiteside bit would not work in spite of being advertised as an equivalent to the 128-8 Leigh bit. I’ve confirmed directly with Leigh that this is often a problem with after-market bits. I’ve used Infinity bits in the past and overall like the quality and value, but need to ensure they are suitable for this application.
