The Radio Lectric #495 hand reamer is a vintage tool made in the United States. This specific tool is designed for reaming holes from 1/8" to 5/16", making it versatile for various machining and drilling needs. With its classic design and durable construction, this hand reamer is a valuable addition to any collection of tools and hardware. While useful for many purposes I believe this was originally used to ream holes drilled in metal where wires are passed through and the holes need to be reamed to remove any burrs that may cut the wire insulation.
