Drill Bit AWTools SDS+ 18 mm, model AW42864

AWTools SDS+ 18 mm drill bit (model AW42864) is a masonry drill designed for use with rotary hammer drills that accept SDS-plus shanks. With an 18 mm cutting diameter, the bit is intended for drilling holes in concrete, brick and natural stone. The SDS+ connection ensures fast mounting and a secure fit in compatible hammer drills, enabling stable rotation and hammering action for demanding construction and renovation tasks.

Advantages

The drill bit combines an 18 mm diameter with an SDS+ shank to provide straightforward compatibility with a wide range of rotary hammers. Its masonry-optimized tip geometry and robust body deliver efficient dust removal and consistent drilling progress in hard substrates. The secure SDS+ engagement reduces wobble and slippage during operation, improving hole accuracy and extending tool life when used with appropriate drilling technique and speeds.

Suitable for

• Drilling anchor and fastening holes in concrete
• Creating through-holes and dowel holes in brickwork
• Installing electrical and plumbing fixtures into masonry
• Renovation and construction site general-purpose masonry drilling

Key specifications

• Cutting diameter: 18 mm
• Shank type: SDS-plus
• Intended materials: concrete, brick, natural stone
• Tool compatibility: rotary hammer drills with SDS-plus chuck

How to use

Mark the drilling position and use an appropriate center punch or pilot mark where necessary. Insert the SDS-plus shank fully into the hammer drill chuck until it locks. Select hammer or rotary-hammer mode depending on the material and machine. Apply steady forward pressure without forcing the bit; allow the drill’s hammer action to do the cutting. Withdraw the bit periodically to clear dust and prevent overheating. For deeper holes, drill in stages and remove debris between passes.

Usage recommendations

Use personal protective equipment including eye protection, hearing protection and dust mask. Match drill speed and hammer settings to the substrate hardness, and avoid excessive side loads that can damage the bit. Replace the bit when cutting performance declines or when visible wear appears on the tip.
