The best bores start with a tool aimed on target. Since accurate alignment is essential, TT Technologies offers aim and launch equipment that assures the Grundomat piercing tool is aligned both vertically and horizontally before the bore is begun. Equipment may be ordered in a convenient kit, or ordered as separate components. See individual items for full descriptions (below).

A kit is available for larger models of the Grundomat piercing tool, and provides a proper match of all components. Kit includes an Aiming Frame, Surveyor’s Stake, Starting Cradle and Anchor Stakes.
