End Mills Concentricity

  • Mini Mill Tooling - LittleMachineShop.com

    End mill holders have a set screw that bears on the flat on the shank of the end mill and so ensure that the end mill cannot slip. Collets are more concentric than end mill holders because they grip all the way around the end mill's shank. Because they fit the end mill closely end mill holders ensure concentricity.
