Concrete Drill Bit Irwin 16.0 mm x 600 mm Speedhammer Plus – SDS‑plus shank, long masonry bit

Irwin Concrete Drill Bit Speedhammer Plus 16.0 mm x 600 mm is a long masonry bit designed for use with SDS‑plus rotary hammers. The 16 mm diameter and 600 mm overall length provide extended reach for drilling through slabs, walls and deep anchor holes. The Speedhammer Plus flute geometry and reinforced carbide tip are engineered to evacuate dust efficiently and maintain drilling speed in concrete, brick and natural stone when used in hammer drilling mode.

Advantages

The bit’s SDS‑plus shank ensures quick, secure fitting and reliable energy transfer from the rotary hammer. Its extended length reduces the need for extensions or repositioning when installing fixings through thick elements. Optimised flute design helps clear debris to sustain cutting action and reduce binding. The reinforced tip improves wear resistance and contributes to consistent hole size and alignment during repetitive drilling tasks.

Suitable for

• Drilling through concrete slabs and masonry walls
• Installing chemical or mechanical anchors and fixings
• Creating deep through‑holes for utilities and conduits
• Site installation and renovation tasks requiring extended reach

Key specifications

• Diameter: 16.0 mm
• Overall length: 600 mm
• Shank type: SDS‑plus
• Application material: concrete, masonry, natural stone
• Geometry: Speedhammer Plus flute for improved dust evacuation
• Tip: reinforced carbide tip for enhanced wear resistance

How to use

Insert the SDS‑plus shank into the rotary hammer chuck until it locks. Select hammer drilling mode on the tool and position the bit perpendicular to the work surface. Start drilling at low speed to establish the hole, then apply steady pressure and allow the hammer action to advance the bit. Periodically withdraw the bit to clear accumulated dust from the hole and flute, especially when drilling deep or through layered materials. Use appropriate drill speeds and feed force recommended by the rotary hammer manufacturer for a 16 mm masonry bit.

Usage recommendations

Use suitable personal protective equipment including eye protection, hearing protection and dust mask when drilling. For reinforced concrete, confirm rebar positions before drilling and consider using a dedicated rebar‑cutting bit if contact occurs. Keep the bit clean and inspect the carbide tip for wear; replace the bit if drilling becomes slow or hole size accuracy degrades.
