Tool cup extension

Description

The tool cup extension provides the required clearances for conducting a vertical 220° partial arc test with a QC20 ballbar on a machine where space is limited. It attaches to the magnetic tool cup and keeps the ballbar stable for reliable measurements.

It has two different outer diameters.

Dimensions: The smaller diameter is 12 mm and the larger diameter is 1/2; inch, to suit metric/imperial collets.
