Punta per trapano a percussione Bosch Expert SDS Clean max-8X — 20 mm diametro, 400 mm lunghezza

The Bosch Expert SDS Clean max‑8X hammer drill bit with a 20 mm diameter and 400 mm length is engineered for rotary hammers with an SDS connection to drill deep holes in concrete and masonry. Its flute geometry and cutting head are designed to reduce clogging and improve dust evacuation during drilling, supporting continuous operation and extended service life of both the bit and the tool. The bit is intended for professional construction and renovation applications that require reliable deep-hole drilling performance.

Advantages

The specialized flute design accelerates debris extraction to maintain drilling speed and minimise heat build-up. The optimized cutting geometry provides stable penetration in reinforced and unreinforced concrete while reducing bit vibration. High-quality material and heat treatment improve wear resistance and extend lifetime under heavy use. Compatibility with SDS rotary hammers ensures secure shank retention and efficient power transfer for demanding drilling tasks.

Suitable for

• Drilling deep anchor and through-holes in concrete
• Creating openings for plumbing and electrical installations in masonry
• Renovation work requiring repeatable, consistent hole quality
• Jobs on construction sites where dust evacuation and long bit life are important

Key specifications

• Diameter: 20 mm
• Overall length: 400 mm
• Shank type: SDS-compatible shank for rotary hammers
• Tip and flute geometry: engineered for reduced clogging and improved dust removal
• Intended material: concrete and masonry (including reinforced concrete)

How to use

Install the bit into a compatible SDS rotary hammer following the tool manufacturer’s instructions until it locks securely. Select the hammer drilling mode and set an appropriate speed and impact setting for the material. Begin drilling with steady, moderate pressure — avoid excessive force to prevent premature wear. Periodically withdraw the bit to clear accumulated dust when drilling deep holes, and allow the bit to cool in continuous heavy-duty use.

Recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask or dust extraction system. For best results in reinforced concrete, combine moderate feed pressure with intermittent bit withdrawal to maintain dust evacuation and prolong bit life. Store the bit in a dry place to prevent corrosion and inspect for wear before reuse.
