I’m getting a .005 of TIR I thought it was my machine so I tore it down and inspected the entire machine measured and ran in everything to make sure it wasn’t my machine then got the same reading. So I’m pretty sure my test bar was made in a Friday at about 4:59 pm or a Monday after a drinking weekend

Rundlauf ohne Mängel, es ist sogar ein Gewinde zum Einzug in den Konus vorhanden. Der Vergleich mit einem zertifizierten Prüfdorn zeigt nur minimale Abweichungen.

Runout was 0.005". Diameter different at different locations along the rod. Don't waste your money like I did.

La caja de envío era inadecuada. Los centros no están muy bien alineados. Sin embargo, por el precio, es una herramienta útil a un nivel moderado.

Was straight but has a sanded spot on it so it looks bad compared to the rest or the polished rod

The straightness of this so called test bar was measured with .0005 accuracy Mitutoyo test indicator and measured off by .005”. This may be good enough for some, but a test bar should be of better quality than this. As they say, you get what you pay for. Just don’t expect in to be straight within .0001” or even .001”.
