Well this is my second hole saw, I damaged the first one and I don't wan't to screw up again. Please can you give me any suggestions on using a hole saw to go through a metal control panel. I've heard before that you need to go through metal slowly so that you don't damage the hole saw. Any suggestions??? BTW this is a Dewalt Bimetal hole saw.... TIA |

How big are the holes that you're drilling? If they're fairly small (less than two inches in diameter), you might want to think about using a knock-out set. Some equipment rental businesses carry them. If you don't know what a knock out set is, try Googling 'greenlee slug buster'. It'll punch perfect holes. Coop |

I know about knockout sets, but they're kinda expensive so I went with the hole saw option. Any suggestions. |

Hmmm, I used a Lenox brand bi-metal 1 1/8" hole saw for 30 holes in 16 guage steel without issue. It was still working like new. I don't think I did anything special other than putting a little machine oil on the panel, so try using a little oil this time. Step bits are another option but they too are a bit pricey at around $50. |

well right now the only oil I have in my hands is Car oil... will that do??? |
