I work in a steel door factory where I work mostly in the assembly department where I use drills and angle grinders. The management is cool enough to let us borrow the tools for home projects so I sometimes bring them home.
I decided to replace shower head holder on the ceramic tile bathroom wall since one of the plastic holders was broken and other one kept coming out of the wall and causing the shower head to rotate. The plastic anchors of the new shower head holder as I am told require 6mm holes. I also got some anchors for the toilet which wasn't fixed (nor there was silicone) which require 10mm holes.
I decided to take CatPower 5920 (920W/980RPM/5180 Impacts Minute) rotary hammer for the toilet business and KL Pro KLDM1850B (Torque 60Nm/28800 Impacts Minute/1800 RPM) for the shower head holder business. My boss told me KL Pro would get a blown engine and told me to take DeWALT DW112S-QS instead (which I won't use anyway since it's not a hammer drill). So I got CatPower and some extension cord and a tape measure for the job
I got some cheap really cheap masonry drilling bits and I guess I will be doing the job. What I am wondering is, there was a jack of all trades/departments (master of fitna and spying) kid at the factory that no matter how I and everyone else told him a DeWALT 18V battery drill that doesn't even have impact isn't suitable for 10mm holes to 1mm thick door frame steel but he would keep doing it non stop anyway.
Would the KL Pro be useful for drilling couple holes to the ceramic tile wall and into the concrete behind? The anchors require 6mm of diameter and 30mm of depth and there is only two of them. I am assuming CatPower won't have many issues drilling a couple of 10mm of diameter and 43mm holes into the ceramic tile floor and the concrete under that.
How does someone know if a drill is just not powerful/durable enough for the job?
