The Brush Research MGB3-1/2-120 Block Cylinder Hone is a precision-ground honing tool designed for use with standard brush handles, delivering consistent surface finishing inside cylinder bores. Built from hardened steel, it provides long-lasting durability through repeated use in demanding shop environments.
Ideal for engine rebuilding, automotive maintenance, and MRO applications, this cylinder hone works to deglaze and refinish cylinder walls to the proper surface finish. The 3-1/2" diameter and 120 grit configuration make it suited for mid-size bore finishing tasks requiring controlled material removal.
