SDS+ Concrete Drill Bit MEGA 18mm (model 81860)

The SDS+ Concrete Drill Bit MEGA 18mm (model 81860) is a purpose-built masonry drill designed for use with rotary hammer drills that accept SDS+ shanks. The bit delivers an 18 mm drilling diameter and features a carbide tip engineered to resist wear and to maintain cutting performance under repeated impact drilling in concrete, natural stone and masonry. The SDS+ connection enables quick and secure mounting in compatible hammer drills, allowing efficient transfer of percussive energy for fast hole making.

Advantages

The carbide-tipped head improves durability and maintains sharpness during heavy-duty drilling. The SDS+ shank design provides reliable retention and rapid bit changes without additional tools. The drill bit is optimized for impact drilling, offering a balance between cutting speed and service life when creating holes in dense materials such as reinforced concrete and brick. Its nominal 18 mm diameter is suitable for common fixing and anchoring tasks.

Suitable for

• Drilling holes for anchor bolts and dowels in concrete and masonry
• Through-holes for cable routing or pipe penetrations in walls
• Preparing fixing points for structural and non-structural fittings
• Site and renovation work where SDS+ rotary hammers are used

Key specifications

• Drill diameter: 18 mm
• Shank type: SDS+ compatible
• Tip material: carbide
• Primary application: concrete, masonry, natural stone
• Use mode: impact (rotary hammer) drilling

How to use

Install the SDS+ shank into a compatible rotary hammer spindle until it locks in place. Select an appropriate drill speed and hammer setting for concrete or masonry; use full hammer action where available. Start drilling at low pressure to establish the hole, then apply steady forward pressure while allowing the hammer action to perform the cutting. Withdraw the bit periodically to remove dust and debris and to prevent the bit from binding. For through-holes, confirm drill alignment before completing the hole.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, dust mask and hearing protection. Match the drill length and diameter to the intended anchor or dowel size and avoid excessive lateral force on the bit. For reinforced concrete, use controlled feed and consider pilot holes when required. Store the bit in a dry place to protect the carbide tip from contamination and damage.
