YANKEE Reamer: 0.374 in Dia, 3/8 in Undersized, Straight Flute

A YANKEE undersized straight-flute reamer is used for precision hole finishing in metalworking, where a slightly smaller diameter is needed for subsequent sizing or coating.

To select the correct undersized reamer, measure the target hole diameter and subtract the desired undersize amount (e.g., 3/8 in). Choose a reamer with matching diameter and flute type—straight flutes for through holes, spiral for blind holes. Ensure the material (HSS) suits your workpiece. YANKEE reamers are a reliable choice for precision work.
