Usage Guide & Tips
-
Drilling Technique:
Start at low speed, apply light pressure to mark the drilling point, then gradually increase speed.
When reaching half the depth, retract the drill briefly to aid in heat dissipation and debris removal.
-
Compatible Tools:
Hand drills, cordless drills, and bench drills (Note: Not recommended for lithium drills below 24V due to insufficient power).
-
Important Notes:
-
Avoid drilling into steel reinforcement bars to prevent edge chipping.
-
For overhead work, maintain a speed of 800–1000 RPM for safety.
-
Regularly inspect the drill bit for wear and replace it as needed to maintain performance.
How It Works
The eccentric tip rotates to easily anchor onto the material, while the main and auxiliary cutters work alternately to create a cross-cutting trajectory. This enables fast, smooth drilling with minimal vibration. The multi-tooth interlocking design enhances durability and is suitable for deep-hole applications.
