Piloted tap???
Gang,
Quick question.... possible situation ... need to tap a hole in, say 1/2" plate, through to the other side, but needs to be "perfectly aligned" and say the plate is mounted on a piece of machinery that can't be moved to another location and the tapping has to be done by hand. Possible solution - is it possible, (or has anyone ever done this), by grinding a "pilot" on the front end of that tap and then relieving the cutting edges again to look almost like factory just behind the end of the pilot? Is this a viable concept? Ken. |
