Broca Bosch 2608836642 PRO SDS Plus‑5X 20 x 550 mm para perfuração com martelo perfurador

The Bosch PRO SDS Plus‑5X 20 x 550 mm drill bit is designed for rotary hammer drilling into concrete and masonry. Its 20 mm diameter and extended 550 mm working length allow deep, accurate bores for anchors, through‑holes and installation channels. The SDS Plus shank ensures secure fit and fast bit changes in compatible rotary hammers, while the carbide tip and optimized flute geometry provide controlled dust removal and consistent drilling performance on reinforced and plain concrete.

Advantages

The drill bit combines a robust carbide tip with reinforced flute design to maintain precision and reduce breakage during heavy use. The long 550 mm length enables drilling beyond standard depths without extensions, and the 20 mm diameter is suitable for common anchor sizes and pipe or conduit passages. Compatibility with SDS Plus chucks gives quick, tool‑free bit changes and steady transmission of percussive energy for efficient progress in hard materials.

Suitable for

• Drilling anchor holes for chemical and mechanical anchors in concrete
• Creating through‑holes for piping, conduits and dowels
• Installing fixings in masonry, brick and blockwork
• Tasks requiring deep bore holes without using extensions

Key specifications

• Shank type: SDS Plus for rotary hammers
• Diameter: 20 mm
• Overall/working length: 550 mm working length for deep drilling
• Tip material: carbide for wear resistance and effective cutting
• Flute design: optimized for dust removal and chip evacuation
• Application material: concrete, reinforced concrete, masonry

How to use

Secure the drill bit in the SDS Plus chuck of a compatible rotary hammer and set the tool to the hammer‑drilling mode. Mark the drilling point and start at low speed to position the bit. Apply steady axial pressure without forcing the bit; allow the hammer action to advance the hole. Periodically withdraw the bit to clear dust from the bore if drilling deep holes, and cool the bit by pausing if it becomes excessively hot. After reaching the required depth, retract the bit while the tool is running briefly to help clear remaining debris.

Recommendations

Use appropriate personal protective equipment: eye protection, hearing protection and dust mask or extraction when drilling. Choose a rotary hammer with sufficient impact energy for a 20 mm diameter hole in concrete. For drilled anchor installations, check recommended hole diameter and depth from the anchor manufacturer and clean the hole thoroughly before inserting the anchor.
