Dear all,
Want to buy new drill for home usage purpose. First priority right now to install ceiling fan in concrete ceiling.
Last time want to drill 6mm-8mm concrete wall using cheap impact drill, took forever

until give up and just borrow Bosch from friend. If not mistaken GSB 500 RE, can do the job but quite slow and need to push really hard. Based on my budget :
Option 1: BOSCH GSB 16 RE (my 1st choice until I found stanley rotary drill below)
Rated power input 701 W

Power output 351 W

Rated speed 0 - 1640 rpm
Drill spindle connecting thread 1/2"-20 UNF

Impact rate at no-load speed 0 - 48000 bpm
Drilling range
Drilling diameter in concrete 16 mm
Drilling diameter in wood 30 mm
Drilling diameter in steel 12 mm
Option 2 : Stanley STEL503K 720W 22MM Rotary Hammer (Any one had experience using this? )
Power 720W
Speed without load 0 - 980 / min (rpm)
Beats per minute 0 - 5200gpm (bpm)

Concrete drilling 22mm (7/8 ")
Drilling in wood 30m (1-3 / 16 ")

Or should I just go for STANLEY STHR272K 5KG
