The Record Power RSBG8 Bench Grinder features fully adjustable tool rests with solid locking mechanisms to give optimum support. The cast iron base and sturdy body reduce vibration to give the smooth operation that is essential for successful and accurate sharpening. Rubber feet also dampen vibration whilst ensuring the grinder does not move during use. The wide body of the machine further increases stability and minimises the load on the bearings for increased life. The 40 mm white stone is ideal for giving a fine finish, particularly to HSS turning tools, while the more coarse grey stone is perfect for rougher grinding and shaping. In addition, the spark guard of the white wheel features a magnifying lens to aid fine sharpening. The build quality and reliability of this grinder is significantly higher than some of the more common and cheaper machines which generally have lower powered motors and are substantially lighter. Record Power grinders are designed to give many years of service and replacement stones are readily available should the original ones become worn out, a sure sign of the robustness of these machines.
