I just received my Jessem yesterday so far I love it. The only issue is that the 9.7mm bit supplied with the jig does'nt drill very well in hardwoods. I tried a 3/8 brad point and that works much better. The 3/8 bit is slightly loose in the 9.7mm guides but so far in my tests it has'nt affected accuracy. Has anyone else have experience with using different size bits with the Jessem?
