The 15 amp motor powers an improved hammering mechanism which more efficiently transfers energy to the bit, improving demolition performance. A new vibration absorbing main handle produces low full-load vibration, resulting in less user fatigue and greater productivity. The H90SG employs a sealed grease system and auto-stop brushes for minimal maintenance and durability.
