Drill bit AWTools SDS-MAX 30×800×940 mm square shank AW43861

AWTools SDS-MAX 30×800×940 mm square shank drill bit is a heavy-duty masonry bit designed for use with SDS‑MAX rotary hammers. The tool provides a 30 mm bore capability with an 800 mm working length and a 940 mm overall length, allowing deep penetration for anchoring, through-holes or service ducting in concrete, stone and brick. The square shank form ensures a positive mechanical coupling with compatible SDS‑MAX chucks for improved torque transfer during rotary and hammer drilling modes.

Advantages

The AWTools SDS‑MAX bit combines a long working length with a robust 30 mm diameter to enable deep, straight holes in hard materials. Its square shank promotes secure seating and reliable torque transfer in SDS‑MAX rotary hammers, reducing slippage under load. The extended overall length gives additional reach for overhead or recessed drilling without the need for extensions. The geometry is optimized for consistent dust removal and stable drilling performance in concrete and masonry.

Suitable for

• Drilling large-diameter holes for anchors and through-bolts in concrete and stone
• Creating service or conduit paths through masonry walls
• Construction and installation work requiring deep, straight holes
• Renovation and demolition tasks where robust percussion drilling is needed

Key specifications

• Drill diameter: 30 mm
• Working length: 800 mm
• Overall length: 940 mm
• Shank type: square shank compatible with SDS‑MAX rotary hammers
• Material application: concrete, masonry, natural stone

How to use

Fit the bit into an SDS‑MAX rotary hammer according to the machine manufacturer’s instructions, ensuring the shank locks securely. Mark the drilling location and start on a low speed to create a pilot seat, then increase speed and apply steady axial pressure while allowing the hammer action to perform the bulk of material removal. For deep holes, periodically withdraw the bit to clear debris and improve dust extraction. Use appropriate personal protective equipment, dust control and fixation of the workpiece.

Usage recommendations

Use the bit with a rotary hammer rated for SDS‑MAX bits and suited to the intended hole diameter. For optimal performance and tool life, avoid excessive lateral force, ensure regular clearing of cuttings, and choose appropriate anchors or fixings sized for a 30 mm hole. For prolonged drilling in reinforced concrete consider checking rebar location and proceed with reduced feed to avoid damage to the bit.
