I have a Bosch 700watt hammer drill that I got from B&Q a couple years ago, mainly used for drilling masonry. Recently I have been using it a lot in our old house and found it not quite up to par. My dad lent my his 15-20 old 500watt hammer, can't recall the brand(not common) and the chuck was broken but it was a million times better than my drill. What took me 30 seconds with my Bosch took 4 seconds with this drill....
So, I'm looking to get a new drill. What exactly makes one drill much better from another? wattage, rpm, brand?...just looking through the screwfix catalogue, it's not 100% clear why drill A costs so much more than drill B......and finally, should I be looking at regular percussion drills or SDS+ drills for drilling masonry? I have about =A375-100 to spend.
