Makita GA4530 Angle Grinder vs Makita 9557PB Angle Grinder

Both are 4-1/2-inch corded Makita grinders at 11,000 RPM, so the choice comes down to switch style and motor headroom. The 9557PB has the stronger 7.5 A motor, a large paddle switch, labyrinth-sealed bearings and a lower vibration rating, which suits all-day metalwork and cutting. The GA4530 is lighter at 4 lbs with a slide switch and a shorter body, which suits one-handed work in tight spots and buyers who prefer a slide switch. Owners of both rate them as dependable, but the 9557PB's extra amperage and dust sealing give it the edge for heavy use.

• Choose the GA4530 if you want the lighter, shorter grinder with a slide switch and lock-on for long grinding sessions.
• Choose the 9557PB if you want more power, a big paddle switch and sealed bearings for steady cutting and metalwork.
