HSD ISO30 ER32 Tool Holder with Retention Knobs and covernut

Covernuts are used to hold and clamp tools into a spindle. Spindles operate at speeds up to 24,000 RPM so it is vital that balanced covernuts are used. Tool holders (also called "Cones") are used in ATC style systems. All tool holders and covernuts on this website are balanced.

Using unbalanced covernuts or tool holders will damage the spindle.

Correct installation of the collet and tool is required to avoid damaging tooling, cones, and spindles.
