## Description

3" (76.2mm) Ball Bearing Solid Steel Balls Precision Balls: desertcart.com: Industrial & Scientific

Review: Solid and HARD - These a solid. I have not put them on a micrometer as I don’t need them that precise and won’t be measuring them. So if you’re in need of solid bearing balls this size, these are it. They’re perfect for my needs. Better than perfect. Just by my hardness tests, don't expect to drill into them. They are HARD steel.
Review: Perfect ! - These 2 1/2” bearings arrived well packaged and in pristine condition. I’m using them as Chinese hand exercise ‘Baoding’ balls, and for that purpose they’re as good as I could ever hope for. 5 Stars for sure ! ***Update: I’ve since also purchased pairs of the 3” and the 1 3/4” to be used as Baoding balls, and all are absolutely perfect. Highly recommended!

### ⭐⭐⭐⭐⭐ Heavy, Useful Steel Balls With Many Applications
*by C***C on August 21, 2025*

I bought these 1.5" (38mm) steel balls to clear clogs in my shop vac hose. Every week I vacuum a chicken coop with wood shavings, and waste clumps sometimes block the hose. These balls are the perfect size and heavy enough to roll through the hose and break up the clog. Even if you don’t have chickens, you might still enjoy them. They’re solid, satisfying to hold, and could be useful for many projects. The finish is polished steel (not chrome), so they may rust over time, but they can be kept in good shape with a little care.
