Drill bit AWTools SDS‑MAX square shank 18 mm × 600/740 mm, AWTools AW43825

AWTools SDS‑MAX square shank drill bit, 18 mm diameter with a working length of 600 mm and an overall length of 740 mm, is designed for long-reach drilling in concrete and masonry. The bit fits rotary hammers that accept SDS‑MAX tooling and is intended for professional and heavy-duty applications requiring deep holes. Its square shank provides secure engagement in compatible chucks and reduces slippage during high-torque operation.

Advantages

The AWTools SDS‑MAX drill bit offers enhanced durability for repetitive drilling in abrasive materials and stable performance in demanding jobsite conditions. Its extended working length enables deep penetration without the need for extensions, while the square shank improves torque transfer and bit retention in SDS‑MAX compatible rotary hammers. The bit's geometry is optimized for efficient dust removal and consistent drilling speed in concrete and masonry.

Suitable for

• Drilling deep anchor or through holes in concrete walls and floors
• Creating long-reach passages for installations such as conduits and rebar positioning
• Heavy-duty construction and renovation tasks requiring reliable SDS‑MAX tooling

Key specifications

• Diameter: 18 mm
• Working length: 600 mm
• Overall length: 740 mm
• Shank type: SDS‑MAX square shank
• Material compatibility: concrete and masonry

How to use

Install the drill bit into a rotary hammer that accepts SDS‑MAX tooling, ensuring the square shank fully engages the tool’s chuck. Use the hammer in rotary-percussion mode for drilling in concrete and masonry. Apply steady, moderate pressure and allow the tool to do the work—avoid excessive force that can cause bit wear or tool overload. Withdraw the bit periodically to clear dust and debris from the hole and to prevent clogging; for extended holes, clear the hole more frequently to maintain drilling efficiency.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Choose a rotary hammer with compatible SDS‑MAX interface and sufficient impact energy for 18 mm diameter deep drilling. For prolonged or repetitive work, monitor the bit for wear and replace when cutting edges are dulled to maintain drilling quality and safety.
