SmartPro Engraving System Universal Collet 3.5mm- 5 Piece Set + Wrench

Air Do Universal Collets are precision-engineered collets designed for secure and reliable graver holding in pneumatic engraving systems. Optimised for use with Air Do handpieces featuring the SPH3 inner shaft, these collets provide excellent concentricity, stability, and control during detailed engraving work.

With a 3.5 mm graver capacity and compact, robust construction, these collets may also be suitable for use with other engraving handpieces on the market that accept 3.5 mm gravers and utilise a compatible collet and inner shaft design. Compatibility with non-Air Do systems will depend on the internal dimensions and chuck mechanism of the handpiece.

Ideal for professional engravers seeking consistent performance, precision, and durability across compatible pneumatic engraving setups.
