DEWALT DWE4257KT-QS is an electric concrete sander for efficient concrete surface sanding. Working close to the edge is possible thanks to the removable front edge of the sander. Power 1500W. Disc diameter 125mm, spindle thread M14. The grinder has a DEWALT motor with a very high copper content, which in turn improves performance. The zero voltage switch prevents the machine from being started unintentionally. Delivered in a handy, hard TSTAK storage bag.
- The electronic stepless speed increases operating control and enables optimal use of the machine with different accessories, for different materials
- An electromechanical clutch reduces the kickback to the user if the blade gets stuck
- The zero voltage switch prevents the machine from starting, even if the switch is on. The switch must first be reset to start the machine.
- The overload protection prevents the machine from overheating by reducing the maximum power until the machine has cooled down
- The dust extraction system removes most of the debris before air enters the engine, preventing wear and scoring
- The vibration-damped side handle increases comfort
- The disc cover can be removed and attached without tools, which increases the flexibility of use
- Field wiring without connectors increases the durability of the motor
- Self-igniting carbon brushes protect the armature from damage, which increases the durability of the motor
- The compact gearbox enables access to tight spaces
- A wear-protected motor increases the durability of the motor
- The non-locking flange prevents overtightening of the disc and locking of the disc
