I'm looking for a new mains powered portable non-SDS 'percussion' drill,
the ten year old B&D is on the way out.

One of its faults is that the plastic sleeved keyless chuck doesn't seem
to put a tight enough grip on the drill bit, even if I put a good
gorilla effort twist on it.

I don't have that problem on another portable key chuck drill, so I'm
wondering if that is a known down side to keyless?. Or is it my twist
chuck just worn out? It gets used for 2mm steel sheet, ally and wood all
up to 10mm.
