Bosch 5 in. Angle Grinder (Corded, 7.5 Amp) vs DeWalt 4-1/2 in. Angle Grinder (Corded, 6.5 Amp)

The Bosch runs a 5-inch disc; the DeWalt runs 4.5-inch. That half-inch sounds trivial until you're trying to get cutting depth on thick concrete or running a large cup wheel across a slab. For masonry and tile work, the Bosch's larger disc means fewer passes and more aggressive material removal. For general grinding and cutting tasks, the DeWalt's 4.5-inch is the industry standard and you'll never miss the extra half-inch.

The Bosch runs 7.5 amps; the DeWalt runs 6.5 amps. But the real difference isn't the number — it's how the power is delivered. Bosch's motor is consistently praised by concrete and tile pros for smooth, sustained output under load, which prevents bogging when you're pushing a cup wheel hard. The DeWalt's 6.5 amps is perfectly adequate for light-to-medium work, but you'll feel it protest under heavy sustained grinding in a way the Bosch won't.

The DeWalt starts at $40 and tops out around $80. The Bosch starts at $60 and can run to $120. For a homeowner or occasional user, that $20-$40 difference is hard to justify when the DeWalt handles most tasks just as well. The Bosch earns its premium specifically in professional masonry contexts — if that's not you, you're paying for capability you'll never use.

DeWalt has deeper North American retail and service center penetration than Bosch — if something breaks, you're more likely to find warranty support locally. Bosch's own community notes the accessory and service gap, particularly in Canada. For a tool you're going to use hard and potentially need serviced, that matters. DeWalt's community consensus score (72 vs 68) reflects this real-world reliability and support advantage.
