FAQ
What materials is this core bit designed to drill?
It is designed for concrete and stone. It is a diamond core bit for heavy-duty drilling work, not a tool for cutting iron, steel or other metals.
What does "laser welded" mean for this product?
The diamond cutting segments are laser welded to the bit body. This construction is specified for heavy-duty drilling, which is why the bit is positioned for demanding concrete and stone applications rather than light-duty use.
Is this bit suitable for cutting metal?
No. This product is intended for concrete and stone only. For metal cutting, a different type of tool is required.
Who is this core bit intended for?
It suits professional users such as contractors, installation teams and stone fabrication workshops that regularly drill concrete or stone and need a durable, heavy-duty diamond core bit.
