    Expert Review

    I had to include this grinder, because it is rather unique. While there are a few other pencil style die grinders on the market, they are hard to find. Of all the pencil die grinders around, Id have to say that this is the best. Working with it reminds me a lot of using my flex-shaft. This compact unit runs at a maximum speed of 56,000 RPM. A twist throttle on the grinder allows you to control that speed, setting it where you need it and leaving it there. The collet is 1/8-inch, not the 1/4-inch that is common for the other die grinders we've looked at, so finding bits for it might be a bit more challenging. However, when you've got to work in a tight space, this pencil grinder is ideal.Rating: 4/5
