Drill bit SDS‑MAX AWTools AW43881 40×800 mm, square shank

AWTools SDS‑MAX AW43881 40×800 mm drill bit with square shank is a long masonry bit engineered for heavy-duty drilling in concrete, stone and similar materials. Designed for use with SDS‑MAX rotary hammers, this 40 mm diameter, 800 mm overall length bit provides extended reach for through-holes, anchor installation and deep drilling tasks on construction sites and renovation projects.

Advantages

The SDS‑MAX design ensures secure retention and efficient power transfer from compatible rotary hammers, while the square shank provides additional stability in certain chucks and adaptors. The long 800 mm length reduces the need to join extension pieces when creating deep or through holes. The 40 mm diameter allows installation of large anchors, sleeves and pipe passages, and the robust carbide tip and flute geometry are optimized for effective dust removal and sustained drilling performance in masonry materials.

Suitable for

• Drilling anchor holes and fixing points in reinforced concrete and blockwork
• Creating through-holes for pipes, conduits and sleeves
• Deep or hard-to-reach drilling tasks on construction and renovation sites
• Heavy-duty masonry drilling with SDS‑MAX rotary hammers

How to use

Fit the drill bit into an SDS‑MAX rotary hammer or into an appropriate adaptor when using the square shank. Securely tighten the tool according to the rotary hammer manufacturer’s instructions. Start drilling at low speed to create a guide, then increase to the recommended operating mode for rotary hammers. Apply steady axial pressure without forcing the bit; allow the tool’s impact action to break the material. Withdraw periodically to clear dust from the hole and avoid overheating; use compressed air or a vacuum where appropriate to remove debris.

Usage recommendations

Always wear appropriate personal protective equipment including eye, ear and respiratory protection when drilling masonry. Verify compatibility of the square shank with your tool or adaptor before use. For clean through-holes and improved dust control, use water extraction systems or HEPA-equipped vacuums where permitted and follow local safety regulations.
