## Long description

Advantages
The solid construction and robust carbide tip provide reliable drilling performance in hard materials while reducing breakage risk.

Key specifications
Diameter: 20 mm
Working length: 400 mm
Total length: 540 mm
Shank type: SDS‑MAX with square contact profile
Material: carbide tip on a hardened steel body (designed for masonry/concrete)
How to use
Install the bit into an SDS‑MAX compatible rotary hammer according to the tool manufacturer’s instructions, ensuring the shank locks securely in the chuck. Select appropriate drilling speed and impact settings for concrete or masonry, apply steady axial pressure and allow the hammer action to drive the bit without excessive force. Withdraw periodically to remove dust and improve cooling when drilling deep holes. After use, clean debris from the flute and tip and store the bit in a dry place to prevent corrosion.
Usage recommendations
Use personal protective equipment including safety glasses, hearing protection and dust mask when drilling. Match the drill mode and power of the rotary hammer to the bit size and material. For reinforced concrete, use measured, controlled feed and verify anchor hole dimensions before installing fixings.
