Drill bits for concrete?

[PaulKemp]

Hey everyone,

Im looking for a 3/4" inch (I think that would be 20mm?) drill bit to mount a concrete anchor. Looked in home pro, where they sold the anchors, but they didn't have the bits. Is there anywhere in Bangkok that I can get them??? Preferably in the city centre, or close to a metro/bts station.

Thanks!

Does your drill chuck accept SDS drill bits?

You can use a smaller bit and work it to make larger hole if you have to. You hanging a safe? My normal is 6-8mm

19mm is closer to ¾" and quite readily available.

20mm is not commonly sold here in my experience.

Thanks for the replies!

The chuck on my drill does accept SDS bits, and I think the biggest they had at the HomePro was something like 16mm or 18. Either way I am still without a bit and there is a lot to be done around the house!

You will need a drill that is sds, otherwise you will be drilling that 1 hole for over an an hour in that 'chuck'

Yep. Got everything set........ all I need is the bit.
