Drill bit MEGA 12 mm SDS+ model 81226

MEGA 12 mm SDS+ model 81226 is an SDS+ drill bit designed for rotary hammers and demolition hammers that accept SDS+ shanks. With a 12 mm cutting diameter, this bit is intended for drilling precise round holes in concrete, masonry and natural stone. The standard SDS+ shank provides quick insertion and reliable retention in compatible hammer drills, making it suitable for construction, renovation and installation work where a 12 mm bore is required.

Advantages

The SDS+ interface ensures fast bit changes and stable seating during rotary hammer operation. The 12 mm diameter delivers a consistent hole size for anchors, dowels and pipe entries. The bit’s tip geometry and flute design are engineered to evacuate dust and chips efficiently, reducing friction and helping maintain drilling progress in hard materials. The construction material provides wear resistance appropriate for drilling into concrete and masonry.

Suitable for

• Drilling 12 mm holes for plastic or metal anchors in concrete and block walls
• Making passage holes for small cables and conduits through masonry
• Preparation of mounting points for shelving, brackets and fixtures on stone and concrete surfaces
• General renovation and construction tasks requiring an SDS+ rotary hammer

Key specifications

• Cutting diameter: 12 mm
• Shank type: SDS+
• Compatible tool type: SDS+ rotary hammers and hammer drills
• Primary materials for use: concrete, masonry, natural stone

How to use

Insert the SDS+ shank into the hammer drill’s chuck until it locks, following the tool manufacturer’s instructions. Use the hammer function on the rotary hammer and apply steady axial pressure while allowing the tool to do the work; avoid excessive lateral force. For deeper holes, periodically withdraw the bit to clear debris and improve dust extraction. Select appropriate drilling speed and impact settings based on the rotary hammer’s recommendations and the hardness of the material.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, hearing protection and a dust mask. When drilling into reinforced concrete, monitor bit wear and replace the bit if cutting performance deteriorates. Use compatible anchors sized for a 12 mm hole and follow substrate preparation and anchor installation instructions for secure fastening.
