Review on 💪 Aluminum Abrasive Grinder: Powerful Grinding and Sanding Solution by Girish Underwood

These serrated lock washers definitely do what I need. still do a lot. At just over $1 each, I will continue to buy these instead of spending $5-6 on big brands. They're still significantly cheaper than Harbor Freight, even if they have theirs for sale, and pretty much the same quality. It is much more convenient and cheaper for me to order bulk packaging from Revain than to drive 20 minutes to the nearest cargo port. The mixed grit pack is very handy as it allows you to move from heavy sanding to lighter jobs.
