Bosch 5 in. Angle Grinder (Corded, 7.5 Amp) vs Makita 4-1/2 in. / 5 in. Angle Grinder (Corded or XGT 40V)

Makita's instant-on, instant-stop trigger response is not a luxury — it's a functional requirement for welding and fabrication work where you're making short, controlled grinding passes on weld beads and metal edges. Bosch's smoother, more gradual power delivery is actually a liability in that context, but it's exactly what you want when you're running a cup wheel across 200 square feet of concrete and need consistent torque without surging. These are genuinely different power delivery philosophies built for different jobs.

Most cordless grinders are a compromise. The Makita XGT 40V is not. It delivers corded-equivalent power for heavy grinding, which means you can actually use it for real fabrication work without the tool bogging down mid-pass. Bosch's recommended configuration is corded-only, which means you're tethered to an outlet. On a job site or in a shop with fixed power, that's fine. On a structural steel project or anywhere mobility matters, Bosch simply can't compete.

Bosch's 5-inch disc gives you more cutting depth than a 4.5-inch disc — and for concrete and tile work, that extra half-inch matters when you're cutting expansion joints, profiling slabs, or undercutting door jambs. Makita offers both 4.5-inch and 5-inch configurations, but its heritage and community reputation is built around the 4.5-inch form factor for metal work. If your primary material is concrete or thick tile, Bosch's 5-inch focus is a genuine edge.

Makita has a wide accessory ecosystem purpose-built for grinding and fabrication — dedicated cutting wheels, grinding discs, wire wheel setups — and the XGT platform is growing fast. Bosch's 18V cordless ecosystem has real gaps in North America: fewer specialty accessories, fewer local service centers, and less shelf presence at big-box stores. If something breaks or you need a specific wheel at 7am before a job, Makita is easier to support. Bosch's reliability means you'll need service less often, but when you do, it's harder to find.
