Drill Bit Smart SDS+ 55 mm (model 20-0550160) for concrete

Smart SDS+ drill bit 55 mm (model 20-0550160) is designed for efficient drilling in concrete and masonry. Built for use with SDS+ rotary hammer systems, this 55 mm diameter bit creates clean, accurate holes for anchors, dowels and through-fixing in reinforced concrete and solid masonry. The design balances cutting performance and durability to meet the needs of professional tradespeople and DIY users working on concrete drilling tasks.

Advantages

The SDS+ shank ensures secure seating and quick bit changes in compatible rotary hammers, reducing downtime. A purpose-shaped carbide tip combined with a robust flute geometry improves dust evacuation and maintains drilling speed in dense materials. The 55 mm cutting diameter provides the size needed for standard heavy-duty anchors and large-diameter fixings while the overall construction resists bending and wear during repeated use.

Suitable for

• Drilling holes in reinforced concrete for mechanical anchors and chemical anchors
• Creating through-holes for bolts and through-fixing in masonry walls
• Preparing mounting points for heavy fixtures such as structural brackets and railings
• Professional construction and renovation tasks requiring large-diameter concrete holes

Key specifications

• Compatibility: SDS+ rotary hammer systems
• Cutting diameter: 55 mm
• Suitable material: reinforced concrete and solid masonry
• Tip material: carbide cutting tip for enhanced wear resistance
• Shank type: SDS+ for secure engagement and quick changes
• Flute design: optimized for dust removal during rotary hammer drilling

How to use

Install the drill bit into the SDS+ chuck of a rotary hammer according to the tool manufacturer's instructions and ensure it is locked in place. Mark the drilling location and, where necessary, use a pilot punch or smaller diameter starter hole to guide the large bit. Begin drilling at low pressure to establish the hole, then apply steady forward pressure while allowing the rotary hammer's percussion action to do the work. Pull the bit out periodically to clear dust from the hole and check progress. Use appropriate drill speeds and modes recommended for concrete on your rotary hammer.

Usage recommendations

Use personal protective equipment including eye protection, hearing protection and a dust mask when drilling concrete. For clean and safe holes in reinforced concrete, remove debris frequently and consider using a vacuum attachment or wet drilling methods if supported by the tool. Inspect the carbide tip regularly and replace the bit if excessive wear or chipping is visible to maintain consistent hole quality.
