Direct Answer
Choose angle grinder disc size by cutting depth, guard compatibility, user handling and product positioning. A 115mm grinder is compact for light trimming, while a 125mm grinder gives more cutting depth and broader B2B appeal. Do not mix guards or discs outside the tool design.
Why Buyers Ask This
Tool buyers often compare 115mm and 125mm grinders because the machines look similar, but guard size, cutting depth, disc availability and safety positioning differ.

|—|—|—|
| Compact handling | Strong | Good |
| Cutting depth | Lower | Higher |
