Drill bit AWTools SDS Max 28 x 800 x 940 mm for rotary hammers

AWTools SDS Max 28 x 800 x 940 mm drill bit is a long-reach rotary hammer accessory designed for drilling deep holes in concrete, masonry and natural stone. With a 28 mm diameter and an 800 mm effective drilling length, this bit fits SDS Max chucks and is intended for professional construction, renovation and installation tasks that require extended reach and stable performance in hard materials.

Advantages

The solid carbide-tipped head design provides efficient drilling in reinforced concrete and masonry while maintaining cutting edge durability. The SDS Max shank ensures secure retention and quick bit changes in compatible rotary hammers. The long working length reduces the need for extensions or repeated re-positioning when creating deep anchor or through-holes, improving jobsite productivity and maintaining alignment during drilling.

Suitable for

• Drilling deep anchor holes in concrete and reinforced concrete
• Creating through-holes for plumbing and electrical installations
• Coring and pilot drilling in masonry and natural stone prior to larger works
• Renovation tasks requiring extended reach without using extensions

Key specifications

• Drill diameter: 28 mm
• Working length (effective drilling length): 800 mm
• Total length: 940 mm
• Shank type: SDS Max compatible
• Tip: carbide-tipped for hard materials
• Primary application materials: concrete, masonry, stone

How to use

Choose a rotary hammer with SDS Max chuck and an appropriate power rating for drilling in concrete. Secure the bit into the tool’s chuck until it locks. Mark the drilling position and, if required, start with a lower speed or rotation to create a guide point. Apply steady pressure and allow the tool to advance under its own impact action; avoid excessive force that can overheat the bit or stress the tool. Clear drilled debris periodically by withdrawing the bit slightly while running, and maintain a straight alignment to achieve clean, accurate deep holes.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust control measures such as a vacuum dust extractor or wet cutting where applicable. For reinforced concrete, consider a pilot hole or pre-drilling strategy and inspect the bit regularly for wear; replace the bit when cutting performance declines or geometry is damaged. Store the bit in a dry place to prevent corrosion and transport it in a protective sleeve to preserve the carbide tip.
