DEWALT 60V MAX* Cordless Brushless 1-1/8 in 15 Kilo Rotary Hammer

Description

Deep core drilling through reinforced concrete walls binds standard electric hammers and sprains operator wrists. The DEWALT 60V MAX* Cordless Brushless 1-1/8 in 15 Kilo Rotary Hammer powers heavy core cutters through structural concrete with 27 Joules of impact energy. Driven by a 60V brushless motor, this massive tool handles SDS-Max drilling and chipping. Feeding dry core bits without clearing slurry jams the bit and overheats internal clutches.

An induction-hardened steel crank mechanism drives an oversized electro-pneumatic striker cylinder inside a heavy cast magnesium gear case. The mechanical safety clutch pairs with DEWALT E-Clutch technology to cut motor torque within a split second of a rebar pinch. The SDS-Max tool holder features oversized alloy steel locking keys to endure brutal torsional shock loads. Spring-mounted handle isolation mounts decouple operator hands from punishing linear recoil forces. Abrasive concrete dust entering the cooling air intakes causes premature wear on stator wire insulation over long shifts.

Heavy Structural Hammer Engineering Array

Industrial foundation drilling requires extreme torsional torque combined with massive kinetic impact force. The mechanical design balances brushless motor efficiency against heavy internal shock loads during continuous deep boring.

• Brushless 60-volt motor delivers massive kinetic striking energy equivalent to large corded pavement breakers
• SDS-Max chuck system secures heavy demolition chisels while allowing rapid one-handed bit changes
• Active Vibration Control system reduces handle vibration acceleration to minimize operator forearm fatigue
• E-Clutch anti-rotation system cuts motor power instantly if the drill bit binds against heavy rebar
• Wireless Tool Control enables automatic remote activation of paired jobsite dust extractors
• Integrated service light alerts operators when internal mechanical components require factory servicing
• Two-stage mechanical impact selector alters strike energy to protect fragile masonry from edge blow-out

High Energy Kinetic Telemetry Analysis

Current draw pulls up to 52 amps from the 60V battery pack during continuous 2-inch coring in structural slab work. The electro-pneumatic piston cycles at 1,080 to 2,210 blows per minute. Striking force measures 27 Joules of linear kinetic energy per stroke. Compressive air cycling inside the striking chamber elevates front barrel temperatures to 148°F during continuous chipping passes. The SDS-Max drive spline withstands up to 110 ft-lbs of torsional side pry force. Sound pressure registers 98 dBA at operator ear level.

Structural Concrete Care Application Limits

Heavy 15-kilo hammers demand physical operator strength and disciplined tool support. Residential electricians running small plastic conduit should not buy this massive breaker because its high impact force shatters brick walls. Prying heavy foundation slabs with the chisel shank while running the motor snaps expensive tool steel inside the chuck.

• Apply high-temperature hammer grease to every chisel shank before sliding it into the SDS-Max holder
• Blow fine silica dust out from the battery connection terminals using clean compressed air daily
• Allow hot battery packs to cool down before locking them onto high-speed multi-bay battery chargers
