claynlr Posted August 22, 2017 Share Posted August 22, 2017 Hey Guys- Looking for advice on the channeling of conduit and electrical boxes in QCON. Anything better to use than the grinder and chipping method? The boxes are done the same way, as in cut the box outline and chip out? Eyecatcher had a neat looking hand tool for raking out the channel smooth after it was chipped out. Link to comment Share on other sites More sharing options...
Pdaz Posted August 22, 2017 Share Posted August 22, 2017 I use a grinder with a masonry cutting disc to cut the edges and a rotary hammer with a broad bit to chase out the channel. The grinder makes a shed load of dust. But at least the rotary hammer is easier on the wrists than a bolster and mallet. I know there are specialist wall box cutters available in the UK ( like below ) but doubt they are available here. Rotary Hammers are available for about 3K baht - I bought a Hyundai from HomePro.. Good bit of kit. Link to comment Share on other sites More sharing options...
Pdaz Posted August 22, 2017 Share Posted August 22, 2017 With a broad bit it eats thru Qcon and other lightweight blocks. Used it so many times since I bought it. Worth the price and no bruised knuckles. Link to comment Share on other sites More sharing options...
carlyai Posted August 22, 2017 Share Posted August 22, 2017 I used the grinder, chisel and hammer, but next time I'd use the specialist bits if I can get them. Lots of dust.Sent from my SM-J700F using Tapatalk Link to comment Share on other sites More sharing options...
sometimewoodworker Posted September 12, 2017 Share Posted September 12, 2017 Don't bother with an angle grinder for the channel, use one of these. it it is designed for the job Link to comment Share on other sites More sharing options...
claynlr Posted September 13, 2017 Author Share Posted September 13, 2017 Thanks STWW. That's the same tool Eyecatcher had. I will look in Global for it. Link to comment Share on other sites More sharing options...

Sent from my SM-J700F using Tapatalk You hold the bottom handle with your left hand and the triangular handle with your right and run the cutting edge (bottom left in the pic) down the wall where you want to cut the channel. If you have to do a lot of channels it's quite slow and hard work using this tool. I found it a lot easier and quicker to first cut five grooves with an angle grinder, and then subsequently use the tool in the picture to clear out the debris.

carlyai Posted September 13, 2017 Share Posted September 13, 2017 Does it do a better job than cutting many groves with a grinder then knocking them out? Probably lot less dust but.Sent from my SM-J700F using Tapatalk Link to comment Share on other sites More sharing options...
