FAQs
Can I use this bit on metal surfaces?
No, this bit is specifically engineered for masonry materials like brick, stone, and concrete. Using it on metal will quickly dull the carbide tip.
Does this bit require a special drill?
It is compatible with any standard corded or cordless drill equipped with a standard chuck.
Why is my battery draining quickly?
If you are pressing too hard, the motor works harder. This bit is designed to reduce resistance; try using a lighter touch.
What does the 70mm measurement refer to?
The 70mm represents the total length of the drill bit, while the 3mm is the diameter of the hole it will create.
How do I know when to replace the bit?
Replace the bit if you notice the carbide tip is chipped, or if it takes significantly longer to drill the same depth in similar material.
Troubleshooting
Bit is sliding or not biting into the surface
Ensure the drill is in hammer mode and apply firm, steady pressure starting at a low RPM.
Excessive heat build-up
Reduce drilling speed and withdraw the bit frequently to clear dust and allow the bit to cool.
Hole is larger than expected
Check that the bit is held perfectly straight and that the drill chuck is not worn or loose.

Setup, Compatibility & Care
To ensure the longevity of your drill bit, always insert it fully into the drill chuck and tighten firmly. The 3mm shank is compatible with standard three-jaw chucks found on most cordless and corded drills. When storing, keep the bit in a dry environment to prevent oxidation on the shank. For maintenance, periodically inspect the carbide tip for signs of chipping; if the tip becomes dull or damaged, it is recommended to replace the bit to avoid excessive tool vibration and inaccurate hole sizing.
