Description
The Lathe Alignment Test Bar MT3 is a high-precision measuring tool designed to accurately align lathe tailstocks and verify spindle concentricity. Engineered for machinists who demand accuracy, this test bar helps eliminate taper errors when turning long workpieces by ensuring perfect alignment between centers or within Morse taper spindles.
Manufactured from hardened EN31 alloy steel, the MT3 alignment test bar offers exceptional rigidity, wear resistance, and dimensional stability. With a maximum run-out of just 0.0002″, it delivers reliable and repeatable results for professional workshops, tool rooms, and industrial machining environments. Supplied in a protective wooden box for safe storage and handling.
