Key specifications
 Diameter: 22 mm
 Overall length: 300 mm
 Shank type: SDS‑Plus
 Suitable material: concrete and masonry
 Quantity: 1 piece
How to use
Insert the SDS‑Plus shank into the chuck of a compatible rotary hammer and ensure it locks securely before starting. Select the hammer drilling mode on the tool and apply steady, moderate pressure while keeping the bit perpendicular to the work surface. Withdraw the bit periodically to clear dust from the hole and allow cooling. For through-holes, drill from both sides when possible to improve hole quality and alignment.
Usage recommendations
Use appropriate personal protective equipment, including safety glasses, hearing protection and dust mask. Match the drill bit diameter to the anchor or sleeve manufacturer’s recommendation and avoid excessive side loads to prevent premature wear. For best results in reinforced concrete, consider using a pilot hole or appropriate carbide-tipped masonry bits and maintain regular inspection of the bit for wear.
