How to use

Secure the Norton Clipper VB Extreme core bit onto an angle grinder or drill with an M14 arbor, ensuring the tool is switched off and disconnected from power during fitting. Mark the drilling location, start at low speed to establish the cut, then apply steady pressure with controlled speed appropriate for the substrate. Periodically withdraw the bit to clear debris and avoid overheating. Use appropriate cooling or dust suppression methods when drilling in dense or reinforced concrete.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Match tool speed and feed rate to the material being drilled and allow the bit to cool between prolonged cuts to prolong life. For reinforced concrete or heavy-duty work, consider pre-drilling pilot holes or using water cooling where compatible with the power tool.
