(Bulb not included) Excellent Grinder ★★★★★ I could not be more pleased with the Grinder it works well,has plenty of power torque and speed to make great knives in short order. The Grinder appears to be solid and well built. I am very happy with this purchase so far. Best sander! ★★★★★ This is the 3rd belt sander I\'ve bought to sharpen knives I\'ve made and it is awesome! Super fast rpm and eats away the steel super fast and does not bog down at all! Perfect for making knives! Great, affordable tool ★★★★★ This is my second grinder-belt sander, now I hav one set up wit a coarse stone and belt, one with medium stone and belt. I do fabrication and metalworking in a small garage and they suit my needs without taking up valuable space or swapt belts endlessly. Eastwood\'s belt selection is limited but thanks to the internet I\'ve found what I need. Again, a great affordable tool, my first is almost 2years old and has performed flawlessly, I expect the new one to also.
