Description
Chipping out structural beam pockets with an undersized hammer turns simple jobs into grueling shifts. The Bosch Demolition Hammer SDS-max 14 Amp cuts through concrete footings and breaks masonry walls with heavy linear strikes. You plug this 14-amp tool into standard 120-volt temporary power lines to produce 12.4 ft-lbs of impact energy. Strike concrete without your chisel seated against the work, and you shatter the front internal stops within weeks.
You open the magnesium gearcase to inspect a precision-machined crankshaft linked to an electro-pneumatic striker. Hardened steel locking pawls inside the SDS-Max nose retain heavy demolition chisels against continuous axial vibration. Dual seals on the armature bearings keep fine concrete dust from cutting into the copper motor windings. A rotating collar locks your flat chisels in twelve positions to match wall seams. Run this tool in winter without fresh grease, and the striker sticks in the rear of the bore.
Concrete Chipping Mechanical Hardware Array
You need hard linear chisel strikes without rotational torque when busting concrete footings down to the rebar. The internal gearset turns electric motor watts into rapid kinetic blows through a spring-cushioned striker.
- 14-amp electric motor delivers reliable kinetic impact power under continuous concrete demolition loads
- SDS-Max chuck holds demolition points and wide scaling chisels against continuous axial vibration
- Constant speed circuits keep your piston cycle rate steady under heavy downward chisel pressure
- Brush service light warns you eight hours before the motor brushes wear down to the copper lead
- Variable speed dial adjusts strike frequency to keep fragile masonry from blowing out at the edges
- Twelve-position collar locks flat chisels at the right angle for vertical wall and floor passes
- Padded side handle clamps anywhere along the barrel to give you solid two-handed control
Kinetic Piston Telemetry Load Analysis
Your current meter pulls 14 amps continuous from standard 120-volt lines under heavy chisel loading in cured foundation footings. The air-cushioned piston cycles from 900 to 1,890 blows per minute. Strike force measures 12.4 ft-lbs per blow into structural concrete. Piston friction heats the aluminum front gear barrel to 142°F during long chipping runs. The SDS-Max tool holder handles 75 ft-lbs of side pry leverage. Noise meters register 96 dBA at your ear.
Masonry Demolition Field Care Directives
You must grease your chisel shanks before each shift to prevent keyway galling inside the chuck. Do not buy this machine if you run core bits for electrical conduit because this hammer has no rotary drilling mode. Prying thick foundation stone with the chisel shank while running the motor snaps your tool steel flush with the nose.
- 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 play to catch worn locking pawls before bits fall out
