What else needs to match?
Makita DGA504: buying checks
Match diameter and bore, then confirm the disc type, speed rating and guard required for the intended task.
- The accessory speed rating must meet or exceed the maximum speed marked on the tool.
- Check the manual for approved disc types, thickness and guard requirements.
- M14 is the spindle thread, not the disc bore; do not use an X-LOCK-only disc.
Makita GA5030R: buying checks
Diameter and bore are initial checks. Disc type, thickness, guard, flange and speed rating must also suit the tool and task.
- Match the disc’s rated speed to at least the grinder’s specified maximum speed.
- Check the permitted wheel type and thickness, mounting flange and required guard in the manual.
- Select the abrasive for the material and operation; a cutting disc must not be used for side grinding.
Makita DGA513: buying checks
Diameter and bore are initial checks. Disc type, thickness, guard, flange and speed rating must also suit the tool and task.
- Match the disc’s rated speed to at least the grinder’s specified maximum speed.
- Check the permitted wheel type and thickness, mounting flange and required guard in the manual.
- Select the abrasive for the material and operation; a cutting disc must not be used for side grinding.

- Use a disc rated for at least the grinder’s specified maximum speed.
- Check the manual’s permitted disc type and thickness, mounting flange and guard.
- Match abrasive and operation to the material; never use a cutting disc for side grinding.
