Review on Walter 13E504 Crimped Threaded Diameter Tool by Fred Vazquez

Revainrating 5 out of 5

Took 5 minutes with Power Brushes

I know they fall apart over time but this one only lasted about 5 minutes before most of the wires came out of the brush. My coffee grinder runs at 10,000 rpm, this is rated at 12,000, so that's not the problem.

Pros
  • Specifications: The carbon steel wire brush is 5" in diameter. This orange brush has a wire diameter of 0.020 inch. This cup brush is designed for a maximum speed of 8600 rpm.
Cons
  • boring pack
