Makita 28mm Cordless Hammer Battery and Charger Sold with HR011GZKV Drill, 40Vmax, Separately, Case

Introducing the fastest-in-class 28mm cordless hammer drill (among 28mm class cordless hammer drills ; as of November 2025, according to Makita research). High-speed drilling improves work efficiency. Furthermore, it remains compact and lightweight even with the dust collection system installed, achieving excellent maneuverability. Drilling speed increased by approximately 30% (compared to conventional Makita models, using a 16mm diameter carbide drill at a depth of 60mm, with concrete compressive strength of 40N/mm2). Improved maneuverability. A redesigned dust collection system has resulted in a significant size reduction compared to conventional Makita models, with a weight reduction of 600g (compared to conventional Makita models with dust collection system attached). One-touch attachment and detachment. Removing the dust collection system converts it into a regular hammer drill. DC 36V (40Vmax), slide-type Li-ion battery. Battery and charger sold separately.
