Drill bit for concrete MODECO SDS+ 18 mm MN-61-187

Concrete drill bit MODECO SDS+ 18 mm (MN-61-187) is a rotary-hammer accessory designed for drilling 18 mm diameter holes in concrete, masonry and other hard building materials. The shank fits SDS+ chucks and the bit is constructed for impact drilling, providing consistent performance for anchor, dowel and installation work on construction and repair sites.

Advantages

The solid carbide tip combined with a spiral flute profile enables efficient dust removal and sustained drilling speed in reinforced concrete and brick. The SDS+ shank ensures quick, secure mounting and reduces play between tool and bit. The bit is balanced to limit wobble during rotation and is hardened to resist wear during repeated impact drilling cycles.

Suitable for

• Drilling 18 mm holes for anchors and dowels in concrete
• Installing electrical boxes and conduit in masonry walls
• Creating fixing points for plumbing and HVAC supports
• General construction and renovation work requiring impact drilling

Key specifications

• Drill diameter: 18 mm
• Shank type: SDS+
• Intended material: concrete, masonry, stone
• Drilling method: impact (rotary hammer)
• Tip material: carbide cutting head
• Flute design: spiral for efficient dust extraction

How to use

Fit the SDS+ shank securely into the rotary hammer chuck following the tool manufacturer's instructions. Mark the drilling point and start at low speed to create a pilot indent, then apply steady pressure while using the impact mode for efficient penetration. Periodically withdraw the bit to clear debris from the hole and prevent overheating. For deep holes, withdraw more frequently to remove dust and allow the bit to cool.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and a dust mask. Select a rotary hammer with compatible SDS+ chuck and sufficient impact energy for 18 mm concrete drilling. Replace the bit when cutting performance noticeably decreases or when the carbide tip shows visible wear or chipping.
