How can I quickly replace the drill bit?
Rotate the keyless chuck at the front, put in the drill bit and tighten it to fix it.
If sparks appear, what is the fault?
Seeing small sparks inside the drill when its on is normal. If there are big sparks near the motor, cord, or battery, its a sign of a problem that needs fixing.
How is the quality of the tools?
The home drill kit is engineered from high-strength, heat-treated chrome vanadium (CR-V) which enhances durability. It features corrosion and rust-resistant finishes in critical areas to prolong tool life.
