Rawlplug Aggressor SDS Plus Concrete Drill Bit 18mm x 460mm

The Rawlplug Aggressor SDS Plus concrete drill bit is a professional-grade tool engineered for high-performance drilling in concrete, brick, and masonry. With a diameter of 18mm and a total length of 460mm, this drill bit provides the reach and stability necessary for deep-hole applications in demanding construction environments. Its robust construction ensures longevity, while the advanced design features allow for consistent results even when working with reinforced concrete.

Advantages

The primary advantage of this drill bit lies in its specialized head geometry, which is specifically designed to maximize drilling speed while maintaining structural integrity. The unique flute design facilitates rapid dust removal from the borehole, which prevents overheating and reduces the risk of jamming during operation. Furthermore, the bit is engineered to minimize vibration, which enhances user comfort and improves the precision of the hole placement, ultimately leading to higher quality work and reduced tool wear.

Suitable for

• Drilling deep holes in concrete and reinforced concrete
• Installation of heavy-duty anchors and fixings
• Masonry work and brickwork renovation
• Professional construction and infrastructure projects

When it may not be suitable

This drill bit is not intended for use on metal, wood, or ceramic tiles, as the specialized carbide tip geometry is optimized exclusively for mineral-based building materials. Using this tool on inappropriate surfaces may result in premature tip damage or poor hole quality.

Key specifications

• Diameter: 18mm
• Total length: 460mm
• Shank type: SDS Plus
• Material compatibility: Concrete, masonry, brick

How to use

Insert the drill bit into the SDS Plus chuck of your rotary hammer drill until it clicks into place. Ensure the drill is set to hammer-drill mode for optimal performance in concrete. Apply steady, moderate pressure while drilling, allowing the tool to do the work. Periodically retract the bit slightly during deep drilling to assist in clearing dust from the hole, which helps maintain speed and prevents the bit from binding.

What to consider before purchase

• Verify that your power tool is compatible with the SDS Plus shank system
• Ensure the 460mm length is sufficient for your specific application depth
• Check that the 18mm diameter matches the requirements of your anchors or fixings

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and hearing protection, when operating a rotary hammer. Inspect the drill bit for signs of wear or carbide tip damage before each use to ensure safety and efficiency.
