Broca de martelo Bosch Expert SDS Clean max-8X, 30 mm de diâmetro de trabalho, 400 mm de comprimento de trabalho

The Bosch Expert SDS Clean max-8X hammer drill bit features a 30 mm working diameter and a 400 mm working length designed for use with SDS-compatible rotary hammers. Engineered for drilling deep holes in masonry and concrete, the bit combines a robust flute design with an SDS shank to provide secure connection, efficient hammer transfer and stable drilling performance during construction and renovation tasks.

Advantages

The carbide tip and reinforced body deliver consistent cutting performance and extended wear resistance when drilling into hard substrates. The SDS shank system ensures quick, vibration-minimising coupling with compatible rotary hammers and allows efficient percussive energy transfer for deep drilling. The flute geometry facilitates dust removal and helps maintain drilling progress in long holes.

Suitable for

• Drilling deep anchor holes in concrete and reinforced concrete
• Creating through-holes and blind holes in masonry and blockwork
• Installing heavy-duty fixings, anchors and through bolts
• Professional construction and renovation drilling tasks

Key specifications

• Working diameter: 30 mm
• Working length: 400 mm
• Shank type: SDS-compatible
• Tip material: carbide cutting head
• Application material: masonry and concrete
• Flute design: spiral for dust evacuation during deep drilling

How to use

Select an SDS-compatible rotary hammer with appropriate power and set it to hammer drilling mode. Securely insert the SDS shank into the tool’s chuck until it locks. Mark the drilling point and start at low speed to position the tip, then apply steady axial pressure while allowing the hammer action to do the cutting. Withdraw the bit periodically to clear debris and prevent clogging when drilling deep holes. After use, clean the flutes and tip to maintain cutting efficiency.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust extraction or a vacuum system when drilling. Match drill diameter and depth to anchor or fixing requirements and avoid side loading; allow the bit to cool between prolonged operations to extend service life.
