Description
Overhead beam scraping and wall tile chipping fatigue arms when using oversized 25-pound demolition hammers. The Metabo HPT 16lb AC Brushless ACDC AHB SDS Max Demolition Hammer with UVP delivers high-velocity chipping in a compact 16-pound chassis. Powered by an 11-amp AC brushless motor, this hammer yields 9.2 ft-lbs of impact energy. Pushing down off-axis on the chisel jams the floating bit holder and drops breaking speed by half.
An Aluminum Housing Body encases an AC brushless motor that operates without carbon brushes, eliminating brush wear and commutator burning. The internal electro-pneumatic drive mechanism encloses an air-cushion piston striker engineered for maximum kinetic energy transfer into the SDS-Max tool shank. User Vibration Protection integrates internal counterweights and flexible handle dampeners to isolate the operator from linear kickback. Sealed ball bearings keep abrasive masonry dust out of internal gears. Hardened grease breakdown inside the piston chamber causes loss of impact force and piston seizure during cold weather.
Brushless Demolition Mechanical Hardware Array
Masonry restoration contractors require sustained linear impact power that runs reliably on generator power cords. The AC brushless drive motor maintains full striking velocity across long jobsite extension cords.
- 11-amp AC brushless motor delivers maintenance-free operation without carbon brush replacement needs
- SDS-Max tool holder accepts heavy demolition bull points, cold chisels, and bushing tools firmly
- Aluminum Housing Body technology combines metal internal durability with lightweight outer handling
- User Vibration Protection uses internal counterweights to cut vibration transfer to operator joints
- Push-button electronic speed selector adjusts striking rate across four distinct impact power stages
- Full-wave electronic controller maintains constant impact frequency even under severe voltage drops
- Twelve-position bit angle settings lock chisels at the optimum attack angle for floor and wall work
Chipping Telemetry Dynamic Load Analysis
Power consumption stabilizes at 11 amps under full mechanical chisel load in reinforced concrete foundations. Impact rate cycles from 1,320 to 2,850 blows per minute, delivering 9.2 ft-lbs of kinetic energy with each stroke. The active counterbalance system lowers handle vibration acceleration down to 8.0 m/s2 during hard slab chipping. Internal pneumatic cylinder friction warms the front aluminum gear barrel to 145°F under continuous operation. Chisel retainer splines endure high shock loading without axial shearing. Acoustic output registers 95 dBA.
Masonry Demolition Field Care Directives
Lightweight SDS-Max hammers require regular bit shank lubrication to preserve internal retainer splines. Plumbers drilling round holes in foundation walls must not purchase this tool because it lacks a rotary drilling mode. Prying heavy slabs with the chisel shank while running the hammer will snap the tool bit inside the SDS-Max chuck.
- Coat the shank of every SDS-Max chisel with high-temperature hammer grease before chuck insertion
- Blow concrete dust out of the rear motor ventilation slots using dry compressed air weekly
- Inspect the SDS-Max chuck retainer sleeve for axial play to prevent loose bit retention failures
