Sanding & Paint Scraper Disc for Drill?

furyou on 26/08/2021 - 20:41

I'm trying to diy some stuff. I have a 20yo plug in B&D drill that still works. I'm looking at
1) Paint And Rust Stripper Abrasive Disc like this
https://www.bunnings.com.au/3m-4-inch-paint-and-rust-strippe…

2) Sanding discs

I see for both there are ones with :
* a shank for the drill built in
* velcro system
* a rubber backing part with shank, and small screw and washer thing in the middle to lock the pad onto the backing

So I ask you, what type is better to get for a cheapo ozb DIY? I'm not going to use it much, I need to strip some paint from outdoor timber patio so I can repaint.

The sanding is also for the same thing, and probably not much else. So (1) I probably use for this 1 job and that's it. (2) I can use if I have other lazy stuff I don't want to sand, but I can't imagine what.

Bunnings has NO C&C for most of these, so I have to decide online and get delivered.

    Those 3M style ones are amazing in an angle grinder for paint or rust on steel but no idea what they'd be like in a drill for timber. The velcro backed ones sound like they're just sandpaper and I'd bet they'd clog quickly and be slower. I'd be tempted to try the 3M one.

      Second this, I got two 115mm poly discs from Amazon for half the price of that Bunnings one and they're spectacular.

      Removing old, layered or oil paint with sandpaper can be slow and frustrating but the fibre disc gives a surface good enough for painting after a single quick pass.

      I'd recommend a fibre disc in an angle grinder; they can be had very cheap secondhand.

    Sanding with a drill isn't easy.
    It'll torque out of control very quickly and may cut deeper than you want to.
    Easier and better results to be had with a proper sander.

    Better to buy a cheap, corded orbital sander from kmart/bunnings/mitre10/whoever. Likely cost less than $30 with a few sheets of sandpaper.
    You will struggle to get a good finish with these sort of discs, it will ding and gouge the timber if you press too hard, or not be effective if you press too soft.

    Either way, expect to spend a couple of hours hand sanding to finish, as you won't get fine results with a power tool on assembled furniture.

      It's not furniture, but my structural frame on my patio. I have some alu/window/doors framing the area, but there's wood holding the roof up. Basically not really noticed when inside, you can see it when outside. It's under the sun so its paint is cracked
      It just seemed mayb it's easier to have 1 tool than store 3. I don't really know what's what.

        It's probably $15 for the disc, or $30 for a tool that you can donate to the Salvos if you don't want it when you are done.
        The sander tool will make it substantially easier.

    Dont recommend a drill for sanding unless you want to take off in bulk and don’t care about the finish, or will be sanding smooth after with a proper sander.
