Dynamic performance Drilling and Screwing

Extremely powerful with 18V 5.0Ah Battery.
Change modes: Drill Driver or Hammer with one switch! Comfortable in any position as highly ergonomic design helps reduce fatigue whatever the position.

Protection technology

The Tough Tool IP* concept includes features such as sensors which monitor batteries and protect against overheating and ‘over-discharge’. This technology ensures reliable, safe and powerful operation for the user.

1: Switch
Increased sealing helps protect against water and dust.

2: Electronics
The electronic circuits in control panel and battery pack are covered by a urethane layer for added dust and water protection.

3: Battery
The battery cells are designed to avoid intrusion of moisture.


Best ergonomics - T SHAPE design

The front and rear of the tool are well balanced for easy movement in any direction. Drilling can be done with precise control and accuracy, even with one hand.

BIT Adaptor (Standard accessory)

A handy adaptor is as standard equipment and is easily stored in drill body when not in use. Bit adaptor: SDS plus chunk EY9HX403E

High flexibility - Dual voltage function

Dual Voltage circuitry detects the battery pack voltage for best performance. So you can choose the power with our high performance 14.4V or 18V battery packs.

Support function: dust collection cup

For added dust protection for both tool and user, we include a dust collection cup. This minimises falling debris when drilling overhead. Available for our other products (EY78A1, EY7840, EY6803).
