I fitted a new mortice lock to a PO door today. Big heavy thing with steel reinforcement to both sides. I started with my Bosch cordless, which went flat after a hour or so,changed battery, and that went a bit later. So to the back up plan of using the B+D Quattro mains drill from around
1992.Christ it is a revelation - so smooth and powerful. And at least 15 years old. When drilling metal, it makes the Bosch feel very amateur.
Mind, it's crap at masonry drilling, and screwdriving, which i tried today - no, you cant control it enough to drive screws in.
And to think I was going to give it away, as I used cordless all the time now.I'm really glad I've kept it - it is invaluable for large wood augers, and even 10mm drills through steel. Alan.
