Drill Bit AWTools SDS Max 16 mm square shank, 800 mm working length, 940 mm total length

AWTools SDS Max 16 mm square shank drill bit, with an 800 mm working length and 940 mm total length, is designed for deep drilling in concrete, stone and similar masonry materials. The bit features an SDS Max connection for secure mounting in compatible rotary hammers and offers extended reach for foundation, anchor and installation tasks that require long holes. Its long working length provides access to hard-to-reach points while the square shank ensures stable contact and transmission of torque during drilling.

Advantages

The SDS Max system provides a reliable, vibration-resistant connection to rotary hammers, reducing the risk of slippage during heavy-duty operation. The 16 mm diameter balances bore size with drilling speed and chip removal, while the 800 mm working length and 940 mm total length allow for deep penetration without the need for extensions. The tool is intended for use in masonry materials, offering consistent hole quality and straightforward compatibility with SDS Max class hammers.

Suitable for

• Drilling deep anchor holes in concrete and reinforced concrete
• Creating passages for pipework and conduits in masonry walls and floors
• Installing foundations, fixings and structural anchors
• Long-reach drilling where standard length bits are insufficient

Key specifications

• Shank type: SDS Max compatible
• Diameter: 16 mm
• Working length: 800 mm
• Total length: 940 mm
• Intended material: concrete, stone and similar masonry
• Application: rotary hammer drilling for deep holes

How to use

Fit the drill bit into a compatible SDS Max rotary hammer according to the tool manufacturer's instructions, ensuring the shank locks securely. Mark the drilling point, start at low speed to establish the hole, then operate at the recommended hammering speed for your rotary hammer while applying steady axial pressure. Periodically withdraw the bit to clear debris and allow cooling; for reinforced concrete use controlled progress to avoid damaging the bit or the rebar. After completing the hole, remove the bit by retracting it from the chuck following the power tool's release procedure.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and gloves. Select a rotary hammer with SDS Max compatibility and sufficient power for long-reach drilling. For extended continuous drilling, allow cooling pauses and clear chips frequently to maintain drilling efficiency and prolong tool life.
