Description
Corded demolition hammers tether operators to noisy generators during critical structural concrete repairs on elevated bridges. The Metabo KHA 18 LTX BL 40 18V Cordless 1 9/16in SDS Max Rotary Hammer bare tool delivers corded-equivalent power with pure cordless freedom. An 18-volt brushless motor generates 8.6 joules of impact energy. Pushing SDS-max core bits beyond four-inch diameters will trip thermal safety limits.
Die-cast magnesium gearboxes house a heavy electro-pneumatic striker assembly supported by double-row cylindrical bearings. The brushless motor wet-end pairs with high-output battery architecture to deliver extreme wattage without thermal motor trip events. Metabo VibraTech handles integrate counter-balanced dampening springs that decouple reciprocating shock from technician hands. An S-automatic safety clutch disengages drive gears mechanically the instant drill bits bind inside structural rebar cages.
Brushless SDS-Max Hammer Specs
Massive electro-pneumatic hammer pistons deliver 8.6 joules of impact energy for rapid anchor hole production. S-automatic safety clutches decouple drive gears mechanically during sudden bit bind-up.
- 1.562-inch solid bit capacity cuts heavy structural anchor holes in cured industrial concrete
- 8.6 joules of impact energy pulverizes hard aggregate during heavy foundation drilling
- Brushless 18-volt motor platform provides corded-grade power with total jobsite mobility
- Metabo VibraTech suspension handle absorbs reciprocating shock to protect worker joints
- S-automatic mechanical safety clutch disengages drive gears instantly during bit bind-up
- Two-mode selector dial shifts between hammer drilling and hammer-only chiseling operations
- SDS-max drive chuck locks large core bits and demolition chisels securely without slip
Hammer Dyno Bench Load Telemetry
Bench testing monitors battery power consumption and impact energy through 5000 PSI cured concrete. Unloaded motor rotation draws 3.1 amperes from the 18-volt battery, surging to 34.2 amperes while driving a 1-1/2-inch bit. Battery terminal voltage drops from 18.2 volts to 15.4 volts under continuous load. Impact frequency stabilizes at 3200 BPM under heavy forward thrust. Decibel sound level meters read 94 dBA at operator ear level. Gearbox casing temperatures climb 26 degrees Fahrenheit after ten deep holes.
Field Service Operational Traps
Neglecting bit shank grease causes high-friction galling that seizes expensive SDS-max bits inside the chuck. Electricians drilling small tapcon screw holes have no use for this heavy hammer. Never operate this tool without securing the auxiliary side handle firmly.
- Coat SDS-max bit shanks with high-temperature chisel paste before every insertion.
- Wipe abrasive concrete grit off the front chuck rubber seal sleeve after every shift.
- Clean battery terminal connections using dry nylon bristle brushes every week.
