Drill bit Bosch SDS plus 18 x 600 mm PLUS-5 for hammer drills

Drill bit Bosch SDS plus 18 x 600 mm PLUS-5 for hammer drills is a long, heavy-duty masonry bit designed for use with SDS‑Plus rotary hammers. With an 18 mm diameter and 600 mm overall length, this bit is intended for drilling deep holes in concrete, masonry and natural stone. The PLUS‑5 geometry on the carbide tip optimizes chip removal and contact with the work surface, resulting in higher drilling speed and reduced wear during repetitive or demanding jobs.

Advantages

The PLUS‑5 tip geometry provides improved centring and faster penetration compared with standard-point bits, while the reinforced shank and flute design increase durability and reduce jamming. The SDS‑Plus connection ensures secure tool engagement and quick bit changes without additional tools. The extended length allows drilling deep anchoring or through-holes in walls and structural elements with fewer extensions.

Suitable for

• Drilling deep anchor and rebar clearance holes in concrete and reinforced masonry
• Creating through-holes for plumbing or electrical installations in walls and floors
• Heavy-duty renovation and construction tasks requiring long-reach drilling
• Work with rotary hammers that accept SDS‑Plus bits

Key specifications

• Shank type: SDS‑Plus compatible
• Diameter: 18 mm
• Overall length: 600 mm
• Tip design: PLUS‑5 carbide geometry for improved drilling speed
• Primary materials: carbide tip with high-strength steel body

How to use

Select an SDS‑Plus compatible hammer drill and ensure the chisel/rotation mode is set appropriately for drilling (rotary hammer drilling mode). Insert the bit fully into the tool chuck until it locks, then position the tip at the marked drilling point. Start at low speed to establish the hole, then apply steady pressure while operating at the recommended speed for concrete. Periodically retract the bit to clear dust and debris from the hole and prevent overheating; for deep holes, remove material more frequently to maintain cutting performance.

Usage recommendations

Use suitable personal protective equipment including eye and hearing protection, and a dust mask or extraction when drilling concrete or masonry. For reinforced concrete, check for rebar location before drilling. To extend bit life, avoid excessive lateral force and allow the tool to do the work; replace the bit when wear significantly reduces cutting performance.
