Drill bit Smart SDS MAX 50 mm (model 18-500520) for concrete

Concrete drill bit Smart SDS MAX 50 mm (model 18-500520) is a one-piece solid-metal replacement bit designed for drilling large-diameter holes in concrete and similar masonry materials. It fits SDS MAX chucks and provides a 50 mm bore suitable for installing rebar sleeves, passing pipes or running electrical and communication cables. The bit is intended for use with SDS MAX rotary‑hammer drills and for professional construction tasks where reliable, deep holes are required.

Advantages

The one-piece solid-metal construction reduces the risk of breakage at the shank and improves durability under heavy impact drilling. The 50 mm diameter allows efficient removal of material to create clean through-holes for mechanical anchors, pipe sleeves or conduit. Compatibility with SDS MAX systems ensures secure retention and proper energy transfer from hammer to bit for consistent drilling speed and reduced stalling in dense concrete. The design facilitates faster drilling progress and longer service life when used with appropriate equipment.

Suitable for

• Drilling large through-holes in concrete and reinforced concrete
• Creating openings for pipes, cable conduits and sleeves
• Preparing holes for chemical or mechanical anchors and rebar passages
• Heavy-duty renovation and structural work on masonry

Key specifications

• Shank type: SDS MAX compatible
• Working diameter: 50 mm
• Construction: one-piece solid metal
• Intended material: concrete, reinforced concrete and similar masonry
• Application: rotary-hammer drilling with impact action

How to use

Install the Smart SDS MAX 50 mm bit into an SDS MAX compatible rotary-hammer according to the tool manufacturer's instructions until it locks securely. Use the drill in hammer or rotary‑hammer mode suitable for masonry. Apply steady axial pressure and allow the tool to deliver impact energy; do not force the bit excessively. Clear drilled material periodically to maintain cutting efficiency and to prevent jamming. After completing the hole, stop the tool before removing the bit to avoid damage to the tool or bit.

Usage recommendations

Use appropriate personal protective equipment including eye and ear protection, dust mask, and gloves. For reinforced concrete, consider pre-scoring or pilot holes where possible, and use water suppression or vacuum extraction to reduce dust. Match drill speed and feed force to material hardness and tool capacity to extend bit life.
