Hi all
I'm getting into model engineering as a hobby and one of the most frequent tasks is drilling small holes. I'm therefore looking to stock up on some drill bits but could do with some guidance on what to get.
Don't want to spend vast sums as I tend to break them pretty frequently so looking at the budget end of things here but are cobalt drill worth the extra.
eg at Toolstation I could get 2 x 4mm cobalt bits for £1.98 or for 30p less I could get 10 x HSS jobber bits. Are cobalt drills 5x better/stronger/sharper etc or is it just a gimmick
I know we're only talking pence here but the 5x factor seems to apply across all sizes
Thanks
Jim
ps I'll be using the bits mainly on mild steel and brass
