Engineered for road construction and concrete demolition operations, the SL-80 handheld pneumatic breaker from Kaituo delivers consistent impact energy for breaking reinforced concrete, asphalt, and medium-hard rock. Manufactured in an ISO 9001 certified facility with SGS-audited quality controls, this 37kg pneumatic tool features a forged alloy steel structure that withstands daily heavy use on industrial job sites. The simple valve design enables quick chisel changes and on-site maintenance, reducing equipment downtime for construction and mining teams.

The SL-80 breaker operates on compressed air power, utilizing a proven valve distribution system to cycle the impact piston. Compressed air enters through the rear air inlet connection, passing through the valve body which alternately directs air to the upper and lower cylinder chambers. This reciprocating piston motion delivers 18.3 impacts per second to the chisel shank, transferring energy through the tool bit into the work material.
All major structural components are forged from alloy steel, with heat treatment applied to wear surfaces including the cylinder bore, piston striking face, and front bushing. The four-bolt handle design distributes operating loads evenly across the body, while the removable front bushing protects the main cylinder from chisel wear and can be replaced without full tool disassembly. The forged latch retainer mechanism allows operators to change chisels in under 30 seconds without specialized tools, supporting efficient transitions between different breaking tasks.
An integrated 30ml oil feeder automatically lubricates the piston and valve assembly during operation, reducing wear on moving parts when connected to standard site air compressors. The dual D-handle configuration with rubber grips provides stable operator control during vertical and horizontal breaking operations.
This pneumatic breaker supports a range of industrial applications across construction, mining, and municipal maintenance sectors. In road construction and repair, the tool breaks reinforced concrete pavement, removes asphalt layers, and cuts expansion joints with appropriate chisel attachments. Foundation work teams use the breaker for concrete removal during building renovation and footing preparation, where the 37kg weight balances breaking power with maneuverability in confined spaces.
Mining operations deploy the SL-80 for secondary rock breaking in ore passes and draw points, reducing oversize material before crushing. Municipal maintenance teams utilize the tool for sidewalk repair, utility trench backbreaking, and emergency demolition work. The tool operates effectively at altitudes up to 3,000 meters without performance degradation, making it suitable for infrastructure projects in mountainous regions.

Technical support includes compressor sizing guidance to ensure proper air volume delivery, on-site maintenance training for operating crews, and troubleshooting assistance via video call for international customers. All units are factory tested at 0.63 MPa operating pressure before shipment, with impact frequency verified against specification.
The SL-80 requires a minimum air delivery of 3.5 m³/min at 0.63 MPa working pressure. For continuous operation in high-temperature environments, a compressor with 4.0 m³/min capacity is recommended to maintain consistent performance. Air line inner diameter should be at least 19mm to prevent pressure drop.
Standard available chisels include moil point, flat chisel, wide asphalt chisel, narrow trenching chisel, and diamond point chisel. All chisels use the R32×152mm shank specification, with working lengths from 300mm to 600mm available. Custom chisel geometries can be produced for special applications.
The 30ml oil feeder provides approximately 4 hours of continuous operation with standard rock drill oil. Operators should check the oil level at the start of each shift and refill when the level drops below 1/3 capacity. Using ISO VG 100 pneumatic tool oil is recommended for most operating temperatures.
Daily maintenance includes: draining water from the air line before connection, checking oil level, inspecting the chisel retainer for wear, and tightening the four body bolts to specified torque. After 50 operating hours, the front bushing should be inspected for wear and the valve assembly cleaned.
The standard SL-80 is designed for dry operation. Underwater breaking requires specialized modifications including exhaust hose connections and corrosion-resistant components. Contact our engineering team for subaqueous application configurations.
At 0.63 MPa working pressure, the SL-80 produces 112 dB(A) at 1 meter distance. Operators should wear hearing protection in accordance with industrial safety regulations. Anti-vibration handle options are available to reduce operator vibration exposure during extended shifts.
