DeWalt DCG407N-XJ 18V XR Brushless 125mm Angle Grinder (Body Only) vs Makita DGA454Z 18V LXT Brushless 115mm Angle Grinder (Body Only)

Pros

• + The only 125mm disc 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
• − 69 Amazon UK ratings is far thinner owner evidence than the Makita or the corded picks on this list

Pros

• + 4.8 stars from 463 Amazon UK ratings, the strongest owner evidence of the seven picks
• + Brushless, with an automatic speed change function that swaps between high-speed and high-torque modes under load
• + Active Feedback sensing Technology shuts the tool off when it detects the wheel binding
• + Makita publishes the full set: 115mm wheel, 8,500 min-1, M14 spindle, 362mm long
• + Runs on 18V LXT, which makitauk.com publishes as more than 225 products

Cons

• − No electric brake: Makita's manual for this model does not describe one, so the disc coasts down
• − Slide switch that locks in the on position rather than a dead-man paddle
• − Superseded in Makita UK's current catalogue by the DGA463, DGA467 and DGA469, and no longer carries a Makita UK data sheet
• − The most expensive pick on this list, and it arrives body only with no pack or charger
