I have a Glastar All Star Grinder. I still have the bit that came with the grinder years ago. I would like to get a coarse bit and a fine bit, and replace my standard bit. However, there seem to be two kinds of grinder heads--the cheaper Twofers or Gel bits, and the much more expensive (like 4 times the price) Glastar brand bits. I am wondering if I need to get the Glastar bits to get the same quality of grinding that I am used to, or will the cheaper bits suffice? Would appreciate advice!
I don't have THE answer, but in my view you most often get the quality you pay for. Cheaper bits will wear more quickly, largely because the bonding is not so good, or there are fewer diamonds for the area. In my view
I have used both the gelbits and the twofers. The gelbits did not seem to last as long, but the twofers are great and that is all that I buy now. I get just as much wear out of them as I did the expensive ones. Tim
