• Flute type: spiral flute for efficient dust evacuation

How to use

Fit the drill bit into an SDS‑MAX compatible rotary hammer according to the tool manufacturer’s instructions and ensure it locks securely. Mark the drilling location, start the hammer at low speed to create a guide point, then apply steady pressure and allow the tool’s percussion action to advance the bit through concrete or masonry. Periodically withdraw the bit to clear dust from the hole and prevent overheating. Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask.

Usage recommendations

For best results, use the Smart SDS‑MAX 12 mm drill bit with a rotary hammer rated for SDS‑MAX shanks and match drilling speed and feed pressure to the material. When drilling deep holes, withdraw the bit regularly to remove debris. For anchoring, check hole depth and cleanliness before inserting anchors or dowels.
