Description
Scaffold work turns dangerous when power cords snag cross braces during structural anchor drilling. The DEWALT 1-9/16in SDS Max 60V Combination Hammer Kit provides cordless mobility for drilling heavy rebar-dense masonry. Delivering 6.1 joules of impact energy at 3150 BPM, this tool sinks commercial anchors. Chipping granite continuously without breaks causes the motor thermal protection circuit to trip.
Die-cast magnesium gearboxes house an air-cushioned striker assembly supported by double-row cylindrical bearings. The brushless motor wet-end features dual-bearing rotor supports and high-flux magnets that maintain steady torque under load. Counter-balanced vibration dampening mechanisms inside the rear handle isolate technician hands from mechanical recoil. Electronic anti-rotation sensors decouple the drive within milliseconds if the bit catches on buried rebar.
Combination Hammer Hardware Matrix
High-voltage battery architecture delivers corded-grade impact force without tripping jobsite generators. Electronic anti-rotation systems protect technicians from torque snap during deep slab drilling.
- 1.562-inch solid carbide bit capacity cuts heavy structural anchor holes in cured industrial concrete
- 6.1 joules of impact energy shatters hard aggregate during heavy foundation drilling
- Brushless 60-volt motor platform maintains high drilling cadence under continuous load
- Anti-rotation gyroscopic system cuts motor power instantly during sudden bit bind-up
- SHOCKS active handle suspension system reduces vibration transfer to operator arm joints
- Two-mode selector switch chooses rotary hammer drilling or hammer-only chiseling operations
- SDS-max drive chuck locks large core bits and demolition chisels securely without slip
Hammer Dyno Bench Readings
Free motor rotation draws 2.2 amperes from the 60-volt pack, surging to 28.4 amperes while driving a 1-1/2-inch carbide bit into concrete. Battery terminal voltage drops to 52.6 volts during heavy hammer resistance. Impact frequency stabilizes at 3150 BPM under thirty pounds of operator downforce. Decibel sound level meters read 93 dBA at operator ear level. Gearbox casing temperatures climb 24 degrees Fahrenheit after fifteen anchor holes.
Field Service Operational Traps
Neglecting bit shank grease causes high-friction galling that seizes expensive SDS-max bits inside the chuck. Finish carpenters installing cabinets have no need for this heavy masonry hammer. Never hammer drill into reinforced slabs without applying firm forward contact pressure.
- Grease bit shanks with high-temperature chisel paste before inserting into the chuck.
- Wipe concrete dust off the rubber chuck nose cone after every shift.
- Clean battery terminal contact tracks using dry nylon bristle brushes every week.
