Review: Perfect! - perfect metal spheres. If you need metal spheres for a project these are great. You can weld on them and the bond is great. I use them in metal art projects and have yet find any flaw with them. Cutting them is not bad but they are strong and seem to be hardened. My metal band saw didn't have any trouble cutting them but I did break a couple of drill bits in the press putting holes in them (may have been not enough lube on the bit during drilling). I love the structural strength of them. Review: Good,metal - Welds good. Heavy enough to drill and tapand holds bolts ## Features - DIY welding project component - 3" hollow steel ball - With a welder & imagination, you can build anything; we supply the hard to find components so nothing gets in your way - 3" steel balls commonly used to make fitness & ninja warrior grip training tools - 3" steel ball works well as a fence post finial or any decorative element in a project - Leave a photo in your review and show us what you built using these 3 inch spheres ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076ZSPYRT | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #1,446,539 in Automotive ( See Top 100 in Automotive ) #1,259 in Arc Welding Equipment | | Customer Reviews | 4.5 4.5 out of 5 stars (63) | | Date First Available | August 29, 2017 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 2 | | Item Weight | 13 ounces | | Item model number | 300BL-2 | | Manufacturer | Columbus Design & Manufacturing, LLC | | Material | Metal | | Number Of Pieces | 2 | | Part Number | 300BL-2 | | Product Dimensions | 3 x 3 x 3 inches | | Shape | Circular | | Thickness | 0.13 Inches | ## Product Details - **Material:** Metal - **Brand:** oumebiu - **Item Weight:** 0.81 Pounds - **Number of Pieces:** 2 - **Item dimensions L x W x H:** 3 x 3 x 3 inches ## Images ![Hollow 3" steel ball weldable DIY project component (2-pack) - Image 1](https://m.media-amazon.com/images/I/81rBSFG1-SL.jpg) ![Hollow 3" steel ball weldable DIY project component (2-pack) - Image 2](https://m.media-amazon.com/images/I/71oXIVUbzHL.jpg) ![Hollow 3" steel ball weldable DIY project component (2-pack) - Image 3](https://m.media-amazon.com/images/I/81K3rnO+z3L.jpg) ## Questions & Answers **Q: Are these solid steel or hollow?
