I'm thinking about buying a cordless grinder and I would appreciate recommendations.
I have an old, very cheap 7inch or 9inch corded grinder gathering dust in the garage. It's one a bought years ago, for doing one job (patio slab cutting) and I've rarely used it since. Big, cumbersome thing.
What I actually want is a grinder that will be a more versatile tool, mainly for metal cutting, cleaning, shaping etc, but also some wood work and maybe brick, tile etc.
I'm a DIYer/hobbyist, so trade-rated durability isn't hugely important. Comfort of use and effectiveness is important.
First up, are 18v units okay, or should I push the boat out and get a 36v?
Brands: Makita, Bosch, Milwaukee? On the other hand, for my purposes, will an el cheapo machine suffice? Is there a big weight/performance/ergonomics difference?
