SDS+ Concrete Drill Bit MEGA 12 mm (model 81230)

SDS+ Concrete Drill Bit MEGA 12 mm (model 81230) is a 12 mm diameter masonry drill bit designed for rotary hammer drills with SDS+ compatible shanks. Engineered for drilling into concrete, stone and brick, the bit is intended for anchor installation, through-holes and general construction tasks. The flute geometry and tip shape promote efficient dust evacuation and consistent penetration, supporting both professional and DIY applications where reliable concrete drilling performance is required.

Advantages

The SDS+ shank ensures secure retention and smooth power transfer in compatible rotary hammers, reducing bit wobble during operation. A carbide-tipped head and optimized flute design increase wear resistance while helping to eject debris from the hole, which improves drilling speed and reduces bit binding. The 12 mm diameter provides a common size for mechanical anchors and fixings, offering a balance between hole size and structural capacity. The bit is suitable for repeated use in masonry work when used with appropriate drilling techniques and compatible tools.

Suitable for

• Drilling holes for anchors and fixings in concrete and masonry
• Through-holes in brick, blockwork and natural stone
• Construction and renovation tasks requiring SDS+ rotary hammer drilling
• Professional trade work and home improvement projects

Key specifications

• Diameter: 12 mm
• Shank type: SDS+ compatible
• Intended materials: concrete, masonry, natural stone
• Tip: carbide-tipped cutting head for masonry
• Flute design: optimized for dust removal and stable drilling

How to use

Install the bit into the rotary hammer’s SDS+ chuck until it locks securely. Select the rotary hammer’s hammer-drill mode and choose an appropriate speed and impact setting for 12 mm masonry drilling according to the drill manufacturer’s recommendations. Start drilling with light pressure to establish the hole, then apply steady, moderate forward pressure while allowing the tool to do the work. Periodically withdraw the bit to clear debris if drilling deep holes, and avoid excessive side load or bending forces that can shorten bit life.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Use water dust suppression or a dust extraction system where required by site conditions. Match the drill’s power and mode to the bit size and the drilled material for best results, and replace the bit when cutting performance noticeably decreases.
