EY79A2 is equipped with a new brushless motor which helps make the tool last twice as long compared to tools with brush motors. Its new ultra-hard chuck jaw tips are brazed into each jaw giving extra strength and helping reduce wear. Plus, the new hybrid semi-electronic switch helps eliminate heavy friction to internal parts of the switch and it also allows for smoother operation.
Powerful to the Finish
The new large brushless motor delivers a high-speed and powerful performance. The newly designed control circuit increases stable current flow to the motor by more than 70%* enabling the high-power output to be evenly maintained until the task has been completed, even during high-load operation.
*Compared with previous brushless motor.
Increased Efficiency and Flexibility
The new “speed control function” lets you to choose from three different low rotation speed settings (high, medium and slow) based on allowable maximum speeds for metal hole saws. It greatly reduces ‘run out’ when using metal hole saws and prevents surface scorching on stainless steel and other materials.
New Advanced Speed Control
New advanced speed control electronics start rotation speed gradually. This enables slow and smooth starts allowing for ultimate control when you start drilling or working with small screws in precise applications.
With EY75A7, you’ll achieve high-power with optimum centre-balanced ergonomics thanks to its compact design and shorter brushless motor. It’s also incredibly comfortable to use, even in narrow spaces.
Multiple Modes for a Variety of Applications
The Impact Driver has four different loads:
• Hard: fastening long bit and bolts
• Medium: fastening for furniture
• Soft: fastening for plaster board
• Self-Drilling Screw Mode: this new mode starts at the highest speed to cut the hole, and then it transfers to High-Impact for power. It automatically switches to a slower mode.
Robust Design for Heavy-Duty Use
Powerful and compact, the new brushless motor delivers approx. 200%* more life cycles thanks to a new brushless motor. Plus, a thicker motor shaft ensures more strength for heavy-use. EY75A7 uses rigid metal parts in the switch and housing increase durability and increase wear.
