Anyone have a good method for removing the plug from a bi-metal hole saw after cutting a hole in steel???
I'm not too happy trying to jab them out with a small screwdriver.
Thanks,

| Sounds more difficult than getting 2" of wood out of a 3" hole saw. Is it similar? Just wedged harder? |

"Just wedged harder?"
Yes, and the sharp edges will cut you. |

Roy, Try clamping the shaft your hole saw in a pair of "vice grips". Then rap the vice grips on a short piece of 2x4 block. The vice grips stop upon impact with the 2x4 but the plug keeps moving due to inertia. It works better the heaver the plug is but it will work with light plugs as well. You really don't have to hit it that hard but I use a block of wood to keep from damaging the locking pliers. Watch your fingers to keep from crushing them between the block and the pliers.

| I'm going to try that! I don't have metal wedged in mine, but I still have 2" of wood jammed in my hole saw from the bathroom work about 2 weeks ago. Not sure how metal works... Roy let us know that. |

Phil,
Your method looks sound but requires removal of the hole saw from the drill press. Was trying to avoid doing that since I was drilling multiple holes.
Thanks,
Now, please tell me your Vice Grips aren't really as rusty as they look.  |

Roy, What are you cutting holes in?
Yes they are rusty... actually they look better on "film". This is a set I found in the mud on the side of the road. Actually they are Craftsmans which I would not buy. I prefer the real thing... are they still made in Dewitt, Nebraska? |

This particular job I was cutting holes in 1/8" steel plate. I have some more pieces to do that are 1/4" flat bar. Picking the plugs out of the hole saw is a PITA.  |

Why don't you and Ron get your heads together and come up with a hole saw with a plug ejector. I hear that Ron can work marvels with mechanical things and performs wonders that defy explanation. After all he has that magic wand that he keeps bragging about.  |

| I wonder if for metal you use a little oil or extra oil, if it helps with removal. |

Michael,
The plugs are sloopy with all the cutting oil. Hole saws work much better in steel with lots of cutting oil. |
