What else needs to match?
Makita DGA452: buying checks
Start with the listed 115 mm diameter and 22.23 mm bore. Verify the accessory speed, application and guard requirements.
- The disc speed rating must meet or exceed the maximum marked speed of the tool.
- Check approved disc types and thickness in the manual.
- Do not select a larger disc because it shares the bore size; confirm the correct guard for the operation.
Bosch Professional GWS 7-115: buying checks
The manual states a 22.2 mm internal diameter. Match the mounting flange and exact tool specification rather than assuming every 115 mm disc fits.
- Use an accessory rated for at least the speed required by the manual and tool label.
- The manual prohibits adapters or reducers for grinding and cutting discs.
- Cutting with bonded abrasives requires the specified cutting guard; follow the manual for disc thickness and application.
Makita GA4530R: 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.
