I got about a million miles on pipe and chicken plants driving a 3 inch cutoff wheel. I swear I can use it like most folks use a pencil. It is my solve everything tool. I appreciate the beauty of using the correct tool for the job but I am not going to invest in a tool for spot welds. I am just to cheap! Figure it is kind of like blowing a bearing off a shaft and never nicking the shaft. I can use a zip wheel just like that! You guys rock.
