| Drilling through diamond plate |
| (1/1) |

You know that stuff that owners of old jeeps put on the corners to cover up rust? Well, I have a 1/8" thick sheet of it that I'm using for a component in my cab and I'll be damned if it isn't the hardest substance on earth. I'm using a fairly decent corded drill and I just drill and drill and drill and barely make any progress. Maybe I need to go pick up a cobalt bit or something. I haven't even finished one hole yet and I need to make about 10 more. |

Sounds like your bit is dull. Go buy some good bits. I would think high speed steel would be sufficient enough for what you're drilling but you may want to buy cobalt bits. Also, I'd recommend marking each hole with a center punch before drilling (if you're not already). edit: Is it stainless diamond plate? SS is not magnetic if you want to check. |

Bit was dull. :-[ After one and a half holes, which took an ungodly amount of time, the bit snapped. So I popped in another identical bit (my bit set came with thee 1/8" bits) and in less time then the first one and a half I drilled the other nine and a half holes. ;D Live and learn. |
