Screwfix have dropped A LOT of stuff recently, they seem to be stocking more and more of their "own brand" items, Energer, Erbauer, No Nonsense & Titan. Also be aware that 75-80% of the tools stocked and sold by Kingfisher Group are remanufactured for them.
ToolStation was initially started by the same people who started Screwfix before it was bought out. Sadly ToolStation has been bought out by Travis Perkins, and a lot of the good stuff disappeared.
If you're looking for specific tools, can I suggest a traditional tool supplier, not a "one stop crap shop". I also fail to see the draw to eBay, 90% of it is now from China and takes an age to arrive, then when it does its either wrong, broken, or worse it never arrives.
I agree, screwfix tooling stocks have plummeted, but what I will say is I have a few titan tools, and all are good sturdy btis of kit. most of all the 5kg sds drill, it has taken a massive battering when I took out a 14 foot poured concrete wall a few weeks ago, just kept going. got a bit hot but never stopped. in fact it got that hot the grease melted in the gearbox and I had to re grease it, but again, never stopped
