pd4dThe PD4D scaler tips are compatible with their DTE scaler handpieces and NSK orinal. PD4D: Can replace the traditional G reamer, used to prepare good endoThe Pd4d bands extend from 1 to 8 eV in binding energy and the Au 5d bands from 1 to 10 eV below the Fermi level. When the ratio AuPd is 3 to 1 up to 1.5 to 1, the band is
