My FIL gave it to me, said he found it in when he was cleanig out an old cabinet shop. It's a very hard composite material of some sort. Fine-grained and powdery when I drilled a hole in it, the "sawdust" smoldered as I was doing so. As you can see in the picture, it kind of chipped off where the drill came through the underside.
I am chewing up a 3-1/2" bi-metal hole saw attached to a Craftsman percussion drill, and not able to get through more than a couple of mm in before it slows the drill down.
Anyone know what this material is? Thinking I might just take it to a metal fabricator or someone with a router. However, I want to call and tell them what I've got before lugging it around.
Any advice on cutting it would also be helpful.
Thanks.
