Advanced Electric Pickaxe Made in China

BOSI Tools is an electric breaker manufacturer from China, offering both Conventional Electric Pickaxes and the Black Warrior Cool Series Electric Pickaxe.

From floor slotting to mining demolition, the core value of an electric breaker lies in converting electrical power into high-frequency, powerful chiseling energy—BOSI combines a power range of 1100W to 1600W with a quick-change chisel system and a vibration-dampening handle, making demolition work more efficient and less labor-intensive.

Working Principle

BOSI electric breakers convert the motor's rotary kinetic energy into linear reciprocating impacts from the piston, acting directly on the tail of the chisel to generate high-frequency chiseling strikes. The current drives a high-power motor, which, through a gear set, moves a crank-and-connecting-rod mechanism, causing the piston to reciprocate at high speed within the cylinder.

As the piston moves forward, it compresses the air inside the cylinder, forming an air cushion that forcefully drives the striker to hammer the tail of the chisel. As the piston retracts, the striker resets, and the chisel returns to its original position under rebound force and its own weight, completing a single hammering cycle.

This process repeats at an extremely high frequency: the 1100W model reaches an impact rate of 3,800 blows per minute, the Black Warrior 1300W model achieves 3,700 blows per minute, and the 1600W heavy-duty model delivers a single impact energy of up to 60J at a frequency of 1,900 blows per minute, using low-frequency, high-energy strikes to tackle hard rock and concrete.

BOSI has specifically tuned the fit precision between the striker and the cylinder, as well as the layout of the vibration-dampening structure, to efficiently convert high-frequency impacts into demolition force, while simultaneously reducing the vibration load experienced by the operator through its dampened handles.

Common Problems During Operation and Solutions

Our Electric Breaker Products vs. Other Brands: Why Choose BOSI?

The core value of BOSI electric breakers lies in concentrating practical configurations such as imported-grade bearings, a quick-change structure, and multiple power options into a reasonably priced package, allowing even small to medium construction teams to use demolition tools whose core performance is not inferior to that of high-end models.

Safety Precautions for Use

Personal Protection

When operating an electric breaker, safety goggles, a dust mask, and noise-cancelling earplugs must be worn. As demolition debris and dust pose significant hazards, it is recommended to wear safety shoes and close-fitting work clothes.

Pre-Operation Inspection

Ensure the chisel is securely locked by the quick-change mechanism. Using a deformed or mushroomed chisel is strictly prohibited. Check that the power cord and plug are intact; for 220V~ models, ensure reliable grounding.

Correct Operating Posture

Hold the handles with both hands. For larger models, always install the auxiliary handle to share the reaction force. Keep your feet apart and stand firmly. During demolition, let the tool's own weight and impact force do the work; do not apply excessive downward pressure.

Notes for Special Models

The toolless auxiliary handle on the 1600W heavy-duty electric breaker can be adjusted 360°; when working vertically, adjust it to the optimal support angle. For work at heights, attach a safety rope and cordon off the protected area below.

Transport and Shutdown

While the breaker is running, never touch the chisel shank. After stopping, always wait for the tool body to come to a complete stop before setting it down. Transporting larger models requires two people to avoid injury from dropping.

Heat Dissipation and Maintenance

Regularly clean the ventilation slots of the housing according to usage frequency, and check the carbon brush length. Store in a dry, ventilated area to prevent motor moisture intrusion.

How to Choose the Right Electric Breaker?

The core logic for choosing an electric breaker is to match the hardness of the demolition material and the duration of the work.

For home improvement tasks such as tile removal and light wall slotting, the 1100W model, with its high-frequency impact of 3,800 blows per minute, is more than adequate, and its body is light and flexible.

For construction site tasks such as partial demolition of concrete structures and pipe trench chiseling, the 1300W Conventional Electric Pickaxe balances single-impact energy with efficiency at 2,900 blows per minute.

If high impact frequency is desired along with the need for frequent chisel changes, the 1300W Black Warrior Cool Series Electric Pickaxe, with its high frequency of 3,700 blows per minute and quick-change design, is the choice for efficiency.

When facing mining rock, thick concrete slabs, or large-scale urban renovation, the 60J single impact energy and imported NSK bearings of the 1600W heavy-duty electric breaker are irreplaceable—low-frequency, high-energy breaking, combined with a 360° adjustable auxiliary handle, maintains stable output even during continuous heavy-duty work.
