Drill bit MODECO SDS+ 12 mm MN-61-157 for concrete

MODECO SDS+ 12 mm drill bit MN-61-157 is a shaft-mounted SDS+ concrete drill designed for drilling into concrete and masonry. With a 12 mm diameter and an SDS+ shank, the bit fits SDS+ rotary hammers to ensure secure seating and effective percussive drilling. It is intended for creating holes for anchors, dowels and through-holes in construction, installation and repair work that require a 12 mm opening.

Advantages

The SDS+ shank enables fast, tool-compatible insertion and a reliable connection to the rotary hammer, reducing slippage during percussion drilling. The 12 mm diameter offers a balance between hole size and drilling speed for typical anchoring and fastening tasks. The bit geometry is optimized for efficient material removal in concrete and masonry, lowering the time required per hole while maintaining dimensional accuracy.

Suitable for

• Drilling holes for expansion anchors and dowels in concrete and brick
• Creating pilot or through-holes for plumbing and electrical installations
• Fastening tasks in renovation and construction where a 12 mm hole is required

Key specifications

• Diameter: 12 mm
• Shank type: SDS+ compatible
• Intended material: concrete and masonry
• Application: percussion drilling with rotary hammer

How to use

Install the drill bit into the SDS+ chuck of a compatible rotary hammer until it locks. Select an appropriate rotation and percussion mode on the tool, and set the correct drilling speed according to the hammer manufacturer’s guidelines. Hold the tool steady and start drilling with light axial pressure to establish the hole, then apply steady pressure while allowing the hammer action to remove material. Withdraw the bit periodically to clear dust and debris from the hole and to reduce heat buildup.

Usage recommendations

Use eye and hearing protection, and a dust mask or extraction when drilling concrete or masonry. For accurate anchor installation, confirm hole depth with a gauge or stop collar and clean the hole of dust before inserting anchors. Replace the bit if wear or chipping reduces drilling performance.
