drill bit for door contact screws -

[bm99]

hey all, normally use 4 x 3/4 screws for the D/c's and just wondering what is the best size drill for these - most of the ones i used to use i think were either 2 or 2.5mm

 

Looking to get a couple of bits for the impact and just use that instead of the combi

 

Thanks

You probably need a 3mm aswell

 

But using in impact? I personally think expensive way to do it , I assume you have speed adjust on your impact and if not using a clip on chuck then using the more expensive drill bits with built on shaft
