Drill bit AWTools SDS‑MAX square shank 18 mm × 800/940 mm by AWTools

AWTools SDS‑MAX square shank drill bit with an 18 mm nominal diameter and a working length of 800 mm (940 mm overall) is designed for rotary hammer drilling in concrete and masonry where extended reach is required. This SDS‑MAX bit fits compatible SDS‑MAX rotary hammers and is intended for applications that demand deep drilling through dense materials. The square shank design ensures secure engagement in the chuck and consistent transfer of impact energy during use.

Advantages

The drill bit provides a long working length that allows drilling at a distance from the tool, reducing the need for extensions and repositioning. Its SDS‑MAX connection offers reliable retention and quick tool changes. The 18 mm diameter is suitable for installing anchors, conduit sleeves, or for creating through-holes in reinforced concrete and masonry. The construction balances rigidity and length to maintain straightness and efficient debris removal during drilling.

Suitable for

• Drilling deep holes in concrete for anchors and fixings
• Creating passages for electrical conduit and plumbing in masonry
• Renovation and construction works requiring extended reach
• Compatibility with SDS‑MAX rotary hammers for professional use

Key specifications

• Shank type: SDS‑MAX square shank
• Nominal diameter: 18 mm
• Working length: 800 mm
• Overall length: 940 mm
• Intended material: concrete and masonry
• Typical use: rotary hammer drilling with hammer and rotation action

How to use

Select a compatible SDS‑MAX rotary hammer and secure the drill bit according to the tool manufacturer's instructions. Mark the drilling location and start at low speed to establish the hole before increasing hammer action. Use steady forward pressure without forcing the bit; allow the rotary hammer's percussion action to remove material. Periodically retract the bit to clear dust and debris and to prevent binding. Observe appropriate cooling pauses when drilling extended depths to avoid overheating.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection, and dust control measures such as a vacuum attachment or wet suppression when applicable. Match the drill bit length and diameter to the anchor or sleeve dimensions and ensure the rotary hammer is rated for SDS‑MAX tooling and for the depth of drilling required.
