Right im needing some good drill bits for drilling through metal.Not any cheap shite that will just go blunt after tickling a piece of metal.

Any serious reccomendations please.

Need to be able to go through stainless steel.

Lies. My dewalt set was wank.

Bosch are shite too. Bought some cheapo ones from wickes and they were better!

If you have an engineering supplies shop go there and spend good money on them, then you can regrind them on a bench grinder.

Think im just gonna nip it down to the local engineers and get him to do it.

Think he said the last time he drilled some locking nuts out he used HSS Cobalt drill bits.Seem cheap enough on ebay but i will prob end up messing it up.

If your going at stainless, you want to use cobalt, and take it slow.

Go to local engineering shop and buy the single sizes you need.

Plenty of drilling lube on them as you use them, otherwise your going to melt the tip.

I personally use high speed cobalt drills from Dormer.

Probably the best drills you can buy for the money.

I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.

Totally forgot i had made this thread.

Anyway i got 2x 5mm Cobalt HSS drill bits from ebay for less than £3.

Wee bit of grease on the tip and they went through stainless steel like a knife through butter.
