How Does a Hammer Drill Work?
The magic of this tool lies in its internal helical mechanism. When you strike the back of the tool with a hammer:
1. The vertical force pushes the bit deep into the screw head, preventing it from slipping (cam-out).
2. The rotational torque created at the same time "breaks" the resistance of the rust and unscrews the screw instantly.
Key Advantages:
•Absolute Power: Unblocks screws that no electric screwdriver can move.
•Reversible Operation: Features a selector switch for clockwise (tightening) or counterclockwise (loosening) movement.
•Durability: The body is made of solid steel to withstand thousands of hammer blows.
•Screw Protection: Because the tip is pressed inward while turning, the chances of it "kicking" and damaging the Phillips or flat head are minimal.
