drill bits

[dig-dug-dan]

Is there a decent set of drill bits out there for drilling metal?

Brought some cobalt ones from screwfix or toolstation, dont seem that great.

happy to spend a bit more for quality

DeWalt Extreme are pretty good

Makita as well do good drill bits for metal. Ive just worn one out and I've used it to drill the holes for about 200 pot rivets. That was through ally and steel. Come to think of it I think the bit was a multi purpose bit. :-)

Dormer or Heller .

What did you find wrong with the Screwfix ones? to brittle? dull too easily?

 

Either way learn how to sharpen them, it isn't too difficult on anything from about 4mm up assuming you have a bench grinder. Even expensive ones while being vastly better than cheap ones will need re-sharpened at some point.

 

Some people don't like Cobalt bits if using a hand drill as they're more brittle than HSS bits which if good quality should be hard enough. Fancy coating are likey to be more effective at attracting consumers than they are at improving performance.

 

As suggested above, Dormer, Heller and I'll add Presto.

Unless you are drilling harder material such as stainless steel where temperature can be an issue, cobalt drills offer no benefit over a decent quality HSS bit.

I bought a budget dormer set a while ago and have been very pleased. However if you are using them in a hand drill they do bite quiet hard.

your as well with a decent hss drill like dormer than a shitty Chinese cobalt drill I found dewalt overpriced for its quality when it comes to drills I have found you get what you pay for reca is another decent make

Are you using a press drill or drilling by hand?

The engineers I work with use dormer drills by the box load, work very nicely and take a sharpen well.

I once had a couple of the makita multi purpose bits as I needed to drill through some steel sheet with a concrete lintel tight behind it and they worked fine, but I wouldn't bother to buy them again unless I had a similar job to do.
