Mounting Block for Spinogy HSK32 Tool Holder
How do you hold the taper while clamping a milling cutter into the tool holder?
This device is the answer. The center bar inside engages in the recess at the bottom of the cone and secures it against twisting while you tighten the union nut.
Especially when loosening the nut, a lot of force is often required to counteract it. Mounting holes therefore make it easier to firmly attach the tool holder to the wall or workbench.
