TS79 Posted October 6, 2012 Share Posted October 6, 2012 Not the type readily available in Soi Paradise! I need to drill a 100mm hole through a double skin concrete wall and need a pretty heavy duty cutter to do it. I only need 1 hole so don't really want to fork out to buy one. I guess I could phone an Air Con shop as they use these tools to make the holes for the pipes through the wall but is a bit cheeky and they probably wouldn't be interested in a few hundred baht only. Any ideas? Anyone have one I could borrow for an hour? I'm in Kathu. Link to comment Share on other sites More sharing options...
LivinginKata Posted October 6, 2012 Share Posted October 6, 2012 Sure it's 100 mm (or 10 cm) you really need. That's a big hole. Not your normal bit size. Link to comment Share on other sites More sharing options...
Old Croc Posted October 6, 2012 Share Posted October 6, 2012 Drill a dozen small holes in a circle and knock the centre out, then patch with cement after inserting drain pipe. Link to comment Share on other sites More sharing options...
phuketsub Posted October 6, 2012 Share Posted October 6, 2012 There is a little mini-mart shop that rents out tools on Trang Road in Rassada, just south of the three-way junction at the start of Rassadanusorn Road (at the border between Phuket Town and Rassada)....I don't know if they have the kind of drill you need though...

TS79 Posted October 6, 2012 Author Share Posted October 6, 2012 @ LIK Doesn't need to be 100mm but certainy bigger than 60mm (kind of drink coaster size). I'm relocating a CCTV DVR with loads of coax cables that need passing through the hole. @ Old Croc I didn't want to take the drilling loads of small holes route as it is very messy and would like a clean cut hole. The two skins are probably 20 - 25cm total depth so would need a long drill bit also or drill from both sides. @Phuketsub Cheers, I'll see if I can find a number and ask them.

pagallim Posted October 6, 2012 Share Posted October 6, 2012 Think that you're talking about a hole saw (concrete specific), not a drill bit. Example here, but don't know where you would actually get one: Link to comment Share on other sites More sharing options...

Example here, but don't know where you would actually get one: Yup, a hole saw just like that. Probably pretty expensive to buy for just 1 hole. I only mentioned drill bit if I was drilling the circumference to knock through but would rather not do it that way. Link to comment Share on other sites More sharing options...
