Li-ion Brushless Impact Screwdriver

The BOSI Black Warrior Cool Series Li-ion Brushless Impact Screwdriver is available in 16V and 20V versions, both with a 1.5Ah battery. It uses a high-quality brushless motor, offering high performance, high torque, and durable new technology. The metal chuck ensures reliable precision and flexible installation and removal.

Dual-speed mechanical adjustment: low speed (0-450 r/min) is suitable for high-torque screwing, and high speed (0-1500 r/min) is suitable for rapid drilling. 23+1 torque settings allow for precise control of nail driving depth, preventing stripping.

The machine is compact and lightweight, easy to hold, and comfortable to operate. Suitable for light work such as furniture assembly, appliance repair, plasterboard drilling, and self-tapping screw installation.

Product Specifications

Common parameters: brushless motor, metal chuck, dual-speed adjustment, torque ring, compact body.

Product Advantages

Brushless motor: Compared to brushed motors, brushless motors have longer lifespan, increased efficiency by more than 20%, and longer battery life with no carbon brush wear.

Dual speed mechanical speed regulation: Low speed and high torque are suitable for screwing screws (such as self tapping into wood), while high speed is suitable for drilling holes (such as wood or plastic), with one click switching.

23+1 gear torque adjustment: subdivided into 23 gear clutches, it can accurately control the output torque, avoiding small screws from slipping or breaking; +The first gear is in drilling mode, and the clutch does not operate.

Metal Chuck: 10mm all-metal ratchet chuck, strong clamping force, high concentricity, convenient and durable for changing drill bits.

Compact and lightweight: ergonomic handle, balanced center of gravity of the whole machine, no fatigue during long-term operation.

High-capacity battery: 16V/20V lithium-ion battery, 1.5Ah capacity can meet daily intermittent work needs.

Li-ion Brushless Impact Screwdriver vs. Conventional Brushed Screwdriver: What’s the Difference?

FAQ

Q: How to choose between 16V and 20V?

A: For daily household use and light DIY, 16V is sufficient; for slightly higher torque (such as tightening long self-tapping screws or drilling hardwood), choose 20V.

Q: What is the difference between a screwdriver drill and an impact screwdriver?

A: Screwdrivers can drill holes and tighten screws, with a clutch to prevent stripping; impact screwdrivers can only tighten screws, and the impact function is suitable for large screws but cannot drill holes. Screwdrivers are the first choice for home users.

Q: Does a higher torque ring number mean more power?

A: Yes. The higher the number, the higher the clutch slippage threshold and the greater the output torque. Use the low setting for small screws and the high setting for large screws. To use drilling mode, switch to the drill icon.

Q: How should batteries be stored when not in use?

A: If not used for a long time, it is recommended to charge to 50%-80% before storage to avoid full or low charge; charge and discharge once every 3 months to maintain activity.

Q: Does a brushless motor require lubrication?

A: No user lubrication required. The internal bearings are pre-lubricated with grease and have a sealed design; no maintenance is required under normal use.
