Product Introduction This handheld pneumatic grinder uses compressed air as a power source to drive gears. Through a pair of meshing gears, the power is transmitted to the grinding blades, causing them to rotate. The high-speed rotating blades grind damaged electrode caps, effectively repairing them. It features a compact size, lightweight design, simple and safe operation, stability and durability; low manufacturing cost; high grinding efficiency; and high-quality, smooth, and aesthetically pleasing finish. Product Features Compressed air driven, grinding speed 80-120 RPM Simultaneous grinding by upper and lower motors Only the blade needs to be changed to grind electrodes of various shapes Weighs 2.25kg, compact, lightweight, easy to operate, and portable Pneumatic quick-connect coupling allows for rapid changeovers.
