A starting point for 4 exact models.
Disc diameter and backing-pad diameter can differ. Read the field label, then check the pad’s extraction-hole pattern and abrasive material as well as attachment.
The models below share the stated size or part reference. Other requirements can differ between tools.

What else needs to match?
Bosch Professional GEX 34-150: buying checks
Choose 150 mm hook-and-loop discs; compare their extraction-hole layout with the pad actually fitted to the tool.
- Check extraction-hole alignment rather than relying only on diameter.
- Choose grit and abrasive type for the material and finish required.
- Replacement backing pads need exact-model approval; a matching disc diameter does not establish pad fit.
Bosch Professional GET 75-150: buying checks
Choose 150 mm hook-and-loop discs; compare their extraction-hole layout with the pad actually fitted to the tool.
- Check extraction-hole alignment rather than relying only on diameter.
- Choose grit and abrasive type for the material and finish required.
- Replacement backing pads need exact-model approval; a matching disc diameter does not establish pad fit.

- Replacement backing pads need exact-model approval; a matching disc diameter does not establish pad fit.
Makita BO6030: buying checks
Use 150 mm hook-and-loop abrasives and compare the extraction holes with the pad actually installed. Pad diameter and abrasive diameter are separate specifications.
- Match the extraction-hole pattern; a nominal diameter alone does not establish dust collection fit.
- Choose abrasive type and grit for the material and finish required.
- Replacement backing pads need exact-model approval; do not use this disc-size guide as pad-fit confirmation.
