Performance and durability are no requirements for the use of the PGM mark. Therefore, the user has the choice between PGM marked hammer drill bits and rotary drill bits, which are suitable for safe anchor installation, with different quality and price levels.
Generally, the quality level of drill bits with PGM mark can be assumed as higher than those of unmarked drill bits, because reliable and quality focussed drill bit manufacturers are normally certified by PGM.
PGM mark has established world-wide as mark for safety and quality of hanmer drill bits (SDS drill bits) and rotary / percussion drill bits. PGM mark is granted to manufacturers only, not to distributors or private labels.
Please find here a list of these manufacturers with conatct details.

SDSplus, SDSmax) and masonry drill bits (rotary or percussion drill bits with cylindrical shank) are marked with PGM mar in addition with the name or trademark of the manufacturer and/or with a manufacturer code (two digit number or letter combination) as follows:
