lithium brushless cordless drill household industrial drilling screw hand-held motor-operated electric tools 锂电无刷充电钻家用工业钻孔拧螺丝手持电动工具

1. Product Features

1. This lithium battery brushless charging drill features a brushless pure copper motor, which avoids the wear and degradation caused by carbon brushes in traditional brushed motors, ensuring smooth and stable power output throughout the device.
2. Equipped with 2,3+1 torque adjustment levels, it supports quick torque switching and can simultaneously perform both drilling and screw removal tasks.
3. With a slender body structure, it features a laser engraving and ergonomic grip design that provides ample friction for holding, suitable for long-term continuous handling tasks.
4. A dual-bearings concentric shaft structure ensures minimal movement of the drill bit during operation, effectively improving the accuracy of drilling and screwing tasks.
5. The device comes with an internal LED light source, which provides illumination in dim and confined working environments such as cabinets, wall corners, and ceilings, eliminating the need for additional lighting equipment.
6. A single machine can perform drilling, screw fastening, and removal, suitable for processing various materials such as wood, metal, and plastic; the wireless lithium battery design eliminates the need for power cables, allowing flexible operation both indoors and outdoors.

2. Product Advantages

1. Compare to standard brushed charging drills: Brushless motor eliminates carbon brush friction loss, reduces heat generation during operation, extends the motor's lifespan, and also results in lower operating noise.
2. A combination of 23 torque mode and counterbore mode allows for both fine screwing with low torque and drilling with high torque—no additional tools are needed to complete different tasks.
3. The handle features anti-slip textures, ensuring stable grip even when the palm is sweaty, thereby reducing the risk of the tool slipping.
4. 10mm specification collet; common twist drill bits and chucks on the market can be mounted directly. The accessories are highly versatile, making it easy and convenient to purchase replacement parts.
5. Dual-speed mechanical speed regulation structure, tightening operations for low-speed gear adaptation, drilling operations for high-speed gear adaptation, with a clear division of speed ranges.
6. Modular detachable lithium battery pack, supports alternate replacement of backup batteries, reduces downtime caused by waiting for charging, and enhances continuous operation efficiency.
7. The entire body is compact and small, allowing it to operate in tight spaces, making it suitable for home repair services and outdoor installation tasks among other complex applications.

III. Product Applications

6. Usage Instructions

1. Battery installation: Push the fully charged lithium battery pack into the bottom slot of the device, hearing a click sound indicates the battery is securely locked; to remove it, hold the side clip and pull the battery downward.
2. Drill bit / Head installation: Loosen the clamp, insert the drill bit or head, tighten the clamp, and ensure it holds firmly without shaking.
3. Torque setting adjustment: Rotate the torque adjustment ring at the front of the unit, and select the appropriate torque level according to the task requirements; when performing drilling operations, rotate it to the flat drill indicator level.
4. Speed gear adjustment: Move the speed control lever at the top of the machine to one side for low speed mode, used for screwing screws; to the other side for high speed mode, used for drilling operations.
5. Turn control: Move the middle direction switch button. Moving it to the left indicates forward rotation and tightening; moving it to the right indicates reverse rotation and loosening. Keeping the button in the middle position activates the safety lock, preventing the trigger from being pressed to start.
6. Power-on sequence: After all settings are completed, pull the trigger. The trigger stroke can control the speed of rotation; the body’s LED supplementary light will turn on simultaneously.
7. Task completed: Release the trigger, wait for the drill bit to stop rotating completely, move the direction switch to the middle safety lock position, and remove the drill bit head; after completing the task, remove the battery and store it separately.

7. Precautions

1. Wear safety goggles for all work activities. When drilling, wood chips and metal debris may scatter; avoid injury to the eyes caused by these debris. It is recommended to wear anti-slip gloves. Do not wear loose clothing or jewelry, as this may cause you to get caught in rotating parts.
2. This device has no impact function, and it cannot drill through thick, hard steel plates or concrete walls. Forced operation will cause the motor to overload and damage.
3. Tool operating status: Do not touch the rotating drill bit or collet. It must be completely stopped before any adjustments are made.
4. Lithium batteries should be kept away from high-temperature sources and open flames. Breaking the battery pack is prohibited; when not in use, remove the batteries and store them in a cool and dry place to prevent water ingress and moisture.
5. During prolonged continuous operation, the body shell becomes significantly hot. It is necessary to stop the machine and let it cool down to prevent the motor from overheating and being damaged.
6. Tools must not be used in humid or rainy conditions to prevent electric leakage risks.
7. The equipment must be placed in a location inaccessible to children, and children are prohibited from operating the machine.
8. If the jaw becomes loose or there is any noise from the device, you must stop using it immediately. Only after identifying and fixing the issue can you continue working.
