I'm installing lots of electrical boxes to the concrete walls in my basement. About 29 boxes and 58 one hole straps to hold the 6 foot length of 1/2" EMT conduit. Choices are a rotary hammer with SDS bit and Tapcon screws. I already own the Makita rotary hammer, bought for this job a year ago. Haven't used the rotary hammer drill yet but I have installed electrical boxes with Tapcon and a hammer drill in the past and hated the hammer drill. Or purchase a Remington powder actuated tool and use the powder and nails. $20 for the hammer hit Remington, $40 for the trigger model that looks like the hammer model, or $70 for the trigger model that looks like a pistol. I've used powder tools to attach 2x4s to concrete and they worked great for that. Cost isn't really a concern since these amounts are not material. Concern is more time, neatness, effort, frustration, etc.
So for attaching 29 handy boxes and the 58 conduit clips to 8 year old concrete walls, which would be the most pleasant to use? Concrete has that brick mold look to it from the forms if that matters.
If powder actuated, does it make sense to get the trigger models so placement of the hndy box or clip on the wall will be easier than with the hammer model?
