DeWalt DCG407N-XJ 18V XR Brushless 125mm Angle Grinder (Body Only) vs Bosch UniversalGrind 750-115 750W 115mm Corded Angle Grinder (Home & Garden)

Pros

• + A 125mm disc, one of three here: more radius than the 115mm picks, which is where depth of cut comes from
• + Three published safety systems - electronic brake, kick-back brake and an E-Clutch that cuts the motor on a pinch or stall
• + Brushless motor with a metal gear housing, a dust-proof switch and mesh covers over the motor vents
• + Guard adjusts without tools and the cutting guard is removable; supplied with guard, side handle and Allen key
• + Runs on DeWalt 18V XR, so a pack bought for a combi drill or impact driver feeds it

Cons

• − DeWalt UK lists the switch as a slide type that locks on, not a dead-man paddle
• − DeWalt UK publishes no no-load speed and no spindle thread for this model, so neither is quoted here
• − Body only: no battery and no charger, so it is only good value if you already run 18V XR
• − A modest owner record on Amazon UK, far thinner evidence than the Makita or the Einhell cordless pick on this list

Pros

• + 750W at 12,000rpm on a 115mm disc, published by Bosch for this model
• + Three straight cutting discs, a side handle and a guard converter in the carton
• + Corded, so there is no battery range to match and no runtime limit
• + Quick-adjust guard and a slim housing Bosch publishes at 1.8kg

Cons

• − No brake, no kickback cutoff, no soft start and no restart protection is published
• − No restart protection, which the blue GWS 7-115 on this page has
• − Tied to a socket by its lead
• − Green Home & Garden: a DIY range rather than Bosch's blue Professional line
