Due to the unique cutting edge shape, nails do not bite in and can be cut safely.
Replace the center drill with PCHWCD225 (carbide) or PCHWCD175 (carbide) when drilling ceramic-based siding.
Please use our company "Hyperdia Core Drill" for hard ceramic siding.
In the case of metal siding, the thickness of the metal part can be perforated up to approximately 0.5, but it is not suitable when the surface of the metal part is planar (no small irregularities).
Use "Gulboud Core Drill" when drilling thick wood.
If the ceramic siding board is not scratched by a 10 yen coin or a nail, use our company "Hypa."
