Is this drill working properly? Makita 8391
I bought this drill...
http://www.screwfix.com/prods/83834/...-Accessory-Kit (but for £100 - don't know why Screwfix made that price up!) I'm concerned the clutch (or whatever it is that lets the drive slip) isn't quite right. On the screw driver setting, even at the _highest_ torque setting, I can stop the shaft turning just by holding the chuck with my hand. On the drill setting, the clutch has no effect (i.e. the drill turns unless it can't - it doesn't intentionally slip). The gap between highest torque and no slip seems ridiculously large. I was using one of the hex bits to drive a bolt into a wall, and it didn't go in at all on the screw driver setting. It went in fine on the drill setting, but then nearly broke something at the end. On both my previous drills, the top setting was far far stronger. On a cordless I borrowed there was still a slightly annoying gap between the top setting and the "drill" setting - but nothing like this! On my old mains drill, the range was continuous, which was ideal. Is this new drill faulty, or is it a design fault, or is it just crap? It's possible, when changing gears or direction, to get the clutch stuck "open", but that's not what I'm talking about here. Even when it seems to be engaged, it doesn't seem to be as strong as I'd like. The batteries don't seem to be that great. I posted a thread on here a few weeks back asking about cordless vs mains. As I drilled a 15mm bit through stone at the weekend, I was wishing for a mains drill - the cordless got through in the end, but it was so slow and kept stopping completely when the bit caught. (There wasn't quite room for my SDS). I thought the batteries were getting flat, but swapping to a freshly charged one only improved things for a few seconds. Cheers, David. |
