Always use the guard but gloves I’m never quite sure, a snagged glove could cause worse injuries than bare hand in some instances. I wear gloves a lot but rotating machines it’s always case by case. I brushed a flap disc against some cut5 gloves and was surprised that it went through very easy, the cut5 are excellent at resisting knife blades etc but seemingly not the discs so chose type carefully too.
Yeah have been looking at more tonight as my current pairs feel like they might show holes any day now. Noticed a lot of gloves that have 'cut 4 or 5' have much lower 'abrasion score' and vice versa.
I have chainsaw gloves, but they'd be a bit bulky for using with a grinder i'd think and only one of them as any real depth of Kevlar, even then I'm not sure how good they'll be against a grinding disc. My Emeralds have been good to me so far; first time not wearing them... ain't that always the way lol
