Hi
I know this topic has already been covered, but I think my questions are a bit more specific. Anyway, if you think they've already been covered, feel free to ignore!
I bought a Makita HR2450 SDS drill the other day. Up until now I have relied solely on my trusty DeWalt 18V cordless combo drill, which seems to be able to do almost anything. Almost. It cannot drill granite (obviously) or large holes in high density concrete, and it struggles with large hole saws (unsurprisingly).
So I chose an SDS drill with a "mechanical safety clutch", as I thought this was what was needed for safe use of large hole saws, and would of course be well suited to granite and concrete. But on reading the instruction it says: "Hole saws cannot be used… They tend to pinch or catch… This will cause the torque limiter to actuate too frequently".
So my questions are:
a) Is their statement about hole saws likely to apply to hole-sawing wood, or just masonry/stone/metals (I never intended to attempt to hole-saw these).
b) In your experience how likely is it that I will find the drill really is incapable of hole-sawing wood, or is damaged by this, and how likely is it that they are just covering their donkeys? I won't hold you responsible if you say it's fine and then I wreck the drill!
I know some of you will be thinking I have the answer in black and white and should just follow the instructions, but I can't justify the cost of two drills (an SDS and a core drill) for two things I don't do that often, nor do I have the space to store them. It would seem ridiculous to keep using my combi for hole sawing when I have this beast of an SDS in my tool kit. Any thoughts from your own experience/knowledge?
Anyway sorry for a long post, thanks for reading to the end!
