This is an ultra-precision workholding tool. When doing the inspection to ensure that each part is wiped especially clean, and the installation must be in place, otherwise it has a great impact on the accuracy

When testing, whether the user's machine tool spindle has errors on the accuracy also has a great impact. So you need to ensure that the accuracy of the spindle of the user's test machine must be high. In addition, please make sure that the accuracy of the ER collet must be high, many ER collets are marked as 0.0005", many of them cannot reach it.

If the accuracy of the collet in the hands of the customer is low, the accuracy of our toolholder is no longer high enough to detect the accuracy.

R8 Shank for Manual Milling: Perfectly fits machine spindles with R8 taper, enhancing milling precision and stability.

ER32 Collet Compatibility: Holds tool diameters from 0.08" to 0.787", offering versatility for various machining tasks.

High-Grade Tool Steel Construction: Ensures durability and resistance to wear, extending the chuck's lifespan.

Ultra-Precise T.I.R. Rating: Maximum T.I.R. of 0.0002" O.D to I.D for unparalleled accuracy in tool alignment and surface finish.

High-Speed Capability: Designed for use up to 8000 RPM, suitable for both high-speed and precision milling operations.
