Another drilling question.

HAHA,

You have to have the carbide drill lined up spot-on, or it will just break or shatter.

The A002 is the way to go, if going to an engineering shop ask them to slot drill the part you have hardened to gain a flat surface again, then centre drill it before drilling. Once you get past the bit you`ve hardened like glass by running the drill too fast it shouldn`t be a problem atall.

Bench mounted drill is probably the best idea.And don`t forget to cool it down with some coolant if you have any, will make the world of difference.

Thats a shame. I had a mental image of me drilling with red hot sparks of carbide flying everywhere. I pictured myself only stopping after setting my clothes on fire and by that point seriously messing up the manifold. Would have been worth if for a laugh, but shattering drill bit sounds a bit boring.

Can't thank you enough, cos knowing me, I probably would have ordered a carbide one anyway, then when it shattered, I would have followed your advice, and pretended they took ages in the post
