Broca Smart SDS MAX 22 mm para betão, modelo 18-220320

Smart SDS MAX 22 mm drill bit (model 18-220320) is designed for percussion drilling in concrete and masonry. This 22 mm diameter bit fits SDS MAX rotary hammers and is intended for making anchor holes, drilling through rebar-free concrete and general construction applications. The bit combines a carbide tip geometry with a robust shank to deliver consistent penetration in standard concrete mixes and common masonry materials.

Advantages

The SDS MAX 22 mm bit offers straightforward compatibility with SDS MAX rotary hammers and stable connection for effective energy transfer during hammer drilling. Its carbide cutting tip maintains edge retention for repeated use in typical construction conditions, while the solid shank resists deformation under heavy load. The design supports efficient dust evacuation and reduces binding in holes when drilling into concrete or brick.

How to use

Secure the drill bit into the SDS MAX chuck of a compatible rotary hammer according to the tool manufacturer's instructions. Position the bit perpendicularly to the drilling surface, start at low speed to establish a guide hole if necessary, then apply steady pressure while operating the hammer function for percussion drilling in concrete or masonry. Withdraw the bit periodically to clear chips and reduce heat buildup. Always verify the required hole depth and use appropriate eye, ear and respiratory protection during operation.

Recommendations

For best results, use the drill bit with a rotary hammer matched to SDS MAX tooling and suited to the required hole diameter and depth. Avoid drilling into reinforced concrete without prior inspection for rebar; if rebar is present, use a specialist bit or cutting method. Clean and store the bit dry after use to extend service life.
