SDS+ masonry drill bit MEGA 16 mm model 81645 for concrete and stone

SDS+ masonry drill bit MEGA 16 mm model 81645 is designed for drilling clean and accurate holes in concrete, natural stone and similar masonry materials. The 16 mm diameter is suitable for common anchor and dowel installations and balances efficient material removal with precise hole dimensions. This bit is compatible with SDS+ rotary hammers and is intended for both professional tradespeople and informed DIY users who need a durable drilling tool for masonry applications.

Advantages

The SDS+ shank ensures secure retention and fast bit changes in compatible rotary hammers. The 16 mm diameter provides consistent hole size for anchors and bolts while allowing efficient dust removal during drilling. The cutting head geometry is optimized for impact drilling in hard materials to reduce walking and improve centring. Manufactured to industry standards, this masonry drill bit offers repeatable performance across multiple drilling tasks.

Suitable for

• Drilling anchor and bolt holes in concrete
• Creating fixation points in natural stone and masonry
• Preparing holes for dowels and pipe clips
• Professional construction and renovation tasks
• DIY projects requiring reliable concrete drilling

Key specifications

• Drill type: SDS+ masonry drill bit
• Nominal diameter: 16 mm
• Intended materials: concrete, natural stone, masonry
• Compatibility: SDS+ rotary hammers with matching chuck
• Typical applications: anchor, bolt and dowel installation

How to use

Fit the SDS+ shank into the rotary hammer chuck until it locks. Select the hammer drilling mode on the tool and start at low speed to establish the centre, then apply steady pressure and increase speed as appropriate. Withdraw the bit periodically to clear dust from the hole for cleaner cutting and to reduce heat build-up. Match drill depth to the anchor or dowel specification and verify hole cleanliness before inserting fixings.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask. For extended drilling in reinforced concrete, verify bit wear and replace when cutting performance declines. Use a vacuum dust extractor or blow out holes with compressed air to remove debris for reliable anchor placement.
