This industrial power tool couldn't handle a standard JOB. The chuck wouldn't grip the drill bit properly and it made excessive noise. Its also quite expensive. While it claims to be industrial and scientific, it doesn't live up to the hype....
If you're drilling holes in steel or stainless steel less than 1/4 inch thick, you've had a miserable life without one of these! a little twist again if you absolutely don't have to.
