Drill bit MODECO SDS+ 20 mm MN-61-197 for concrete

MODECO SDS+ 20 mm drill bit MN-61-197 is made for rotary-percussion drilling in concrete, masonry and natural stone using SDS+ rotary hammer drills. The 20 mm diameter produces medium-size holes suitable for general anchoring and fixing tasks. The bit's design and materials are intended to provide reliable penetration and consistent drilling performance for both professional tradespeople and informed DIY users.

Advantages

The SDS+ shank ensures secure, wobble-free coupling with compatible rotary hammers, enabling efficient transfer of percussive energy to the cutting tip. The 20 mm diameter balances hole size and drilling speed for common anchor and dowel applications. Constructed for impact drilling, the bit maintains cutting performance in hard substrates while offering predictable wear characteristics under normal use.

Suitable for

• Drilling anchor and dowel holes in concrete
• Masonry drilling: brick and block
• Holes in natural stone and similar hard substrates
• Professional construction and renovation tasks
• DIY fixes requiring medium-diameter holes

Key specifications

• Shank type: SDS+ compatible
• Nominal diameter: 20 mm
• Intended use: rotary-percussion drilling
• Primary materials: concrete, masonry, natural stone
• Application level: professional and DIY

How to use

Install the bit into an SDS+ rotary hammer according to the tool manufacturer's instructions, ensuring the bit is fully seated and locked. Select an appropriate drilling mode (rotary-percussion) and set drill speed and impact settings to match the substrate and hole diameter. Apply steady, moderate axial pressure; allow the hammer action to perform the cutting rather than forcing the bit. Periodically clear dust from the hole to improve drilling efficiency and cooling. Replace the bit when cutting performance visibly degrades or the tip shows significant wear.

Usage recommendations

Use compatible SDS+ rotary hammers with appropriate power for 20 mm drilling. Wear eye, ear and respiratory protection when drilling concrete or masonry. For anchoring, verify hole depth and cleanliness before installing fasteners; use recommended anchors for the substrate. Store the bit dry and protected from impact to preserve tip geometry.
