Print ArticleDon’t work the bit too hard. If you are pushing your router
so hard into the stone that the bit sparks or your router slows down, you are working the bit too hard and it will cause premature wear-out.
Use the proper speed. Remember this general rule: For your positions 1 and 2 bits, use the fastest speed possible. Slow speeds won’t cut fast enough and will also cause the bit to glaze. If this happens, you can buy a dressing stone that will unglaze the bit.
Remember, when purchasing any tooling, always ask for performance stats. If the dealer has no idea, ask him for the names of some other fabricators who do so that you can talk to them.
