Like our core bits, Safari’s casing shoes and rod shoes can be custom-made to non-standard specifications. You can special order any dimension, if we can adapt our equipment to produce it to our quality standards.
Set diameters shown here are for the outer or inner measurements of the matrix body on the casing shoe or rod shoe crown. Depending on the application, Safari applies diamonds and tungsten-carbide, alone or in combination, to keep tolerances constant during drilling.
