CONCEPT
01
FEATURES
Cutting-Edge Technology for Superior Fastening Performance
02
Advanced Impact Torque Control with 3 new technologies
01
High Resolution Encoder Sensor
Encoder sensor monitors motor’s rotation angle precisely and simulates snug torque accurately.
02
7 stages Snug Torque Detection Mode
Precise Snug Torque Detection Mode enables accurate fastening on variety of joints with large snug torque.
03
Consistent Impact Control
Powers of impacts are always kept consistent regardless of remained battery capacity.
High Efficiency Double Hammer Block
(EYFLA9, EYFMA2 only)
Reduce Vibration, Increase Comfort
Newly developed Double Hammer lock reduces tool’s vibration, and thus operator’s fatigue and reflection noise from work material.
