DeWalt DCG407N-XJ 18V XR Brushless 125mm Angle Grinder (Body Only) vs Einhell Professional TP-AG 18/125 CE Q 18V Power X-Change Brushless 125mm Angle Grinder (Body Only)

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, thinner evidence than any other cordless pick on this list

Pros

• + Brushless, rated by Einhell at the equivalent of a 900W corded grinder
• + Speed dial from 3,000 to 10,500rpm with an LED display, and electronics that hold speed under load
• + An exceptional owner rating on a substantial Amazon UK record, sold and dispatched by Amazon
• + Runs on Power X-Change, which Einhell lists as over 300 devices

Cons

• − No electric brake and no kickback cutoff, so the disc coasts down
• − Costs more than the brushed Einhell grinders it sits above
• − Body only: no battery, charger or disc in the box
