Machine Mart do a 25 piece set for £46

 

Justoffbase do a 19 piece set for £37

 

Any better deals?

Seems like a lot to pay, when you only use 2 or 3 sizes mainly. Is it not cheaper to buy them separately?

[Guest Battery Bill]

Yes much better but I can't tell you where

You can probably guess from that

[Guest brummy-ade]

screwfix do a set of 7 bits for 7.99 order on line

[Guest daveg]

Just brought 7 drill bits for £19 from Here

 

Might have been better getting a set :boohoo:

[Guest Battery Bill]

Anyway, surely you dont need that many cobalts, we have only used a couple so far and one of them snapped!

i had diff findin a supplier so in the end bought 4 x hss 1/8 (£3 approx) hundreds of holes later have 1 left the other 3 i broke? no prob with blunting and at that price the only pain experienced was when me knuckles hit the car!

[Guest Phil Slater]

I found this place on the web which sells them individually but they are not cheap.

I actually bought a set of 19 from Screwfix, (currently £26.99), but I bought them prior to my build starting - in anticipation!! As Bill says though, I haven't used the majority of them. In fact I've got on well just using jobber drills.

I used warehouse direct for mine, and very pleased with the performance to date.

Still got a lot of holes yet to drill.

I bought a set of drill bits/ screwdiver bits in a case ....Performance Power from B&Q with so called Titanium coating for £7.99,I just drill holes working up from a small size ,to the largest size,and they have lastest ages,the only problem I have

encountered is bits breaking,due to snagging on the stainless.

I must admit I bought a number of Colbalt bits and they are good but can be expensive.

 

I now use Dormer Jobber HSS bits....even though they don't last as long they so cheap you can't go wrong.

To stop drills breaking...drill slower

 

I brought a 25 piece set, TiN coated from ScrewFix with the intension of replacing blunt bits with Cobalt...in hindsight I should have brought a complete Cobalt set :boohoo:

 

The theory was any well used bits would be worth replacing with better quality ones and rearly used bits could remain TiN...but, the cost of just a few bits brought individually cost almost as much as a complete set...more money wasted :boohoo:

 

So the advice to new builders...buy a complete set of Cobalt bits and some drilling oil and drill very slowly, and of course...put the battery in the front

some drilling oil

Not needed !

put the battery in the front

Not true

If you use oil you will notice the difference less heat=better cutting and less snag (less likely to break drill bit)

I have never used oil on normal drilling only if using really "Big" drills and I have never had any problems, just makes a mess bloody oil everywhere
