Drill Bit AWTools SDS‑MAX 20×600×740 mm, AWTools AW43731

AWTools SDS‑MAX 20×600×740 mm drill bit is a heavy‑duty masonry and concrete drilling tool designed for professional hammer drills with an SDS‑MAX shank. With a 20 mm diameter and a 600 mm working length, this bit enables deep, straight holes for anchors, rebar sleeves and through‑holes in construction and renovation projects. The 740 mm total length provides extended reach while maintaining rigidity for accurate drilling in reinforced concrete and thick masonry.

Advantages

The SDS‑MAX shank ensures secure fitment in compatible rotary hammer chucks and efficient power transfer from the tool to the cutting head. The long working length allows drilling of deep anchor and rebar holes without the need for extensions, while the bit geometry and carbide tip are engineered to resist wear during repeated use in abrasive materials. The bit’s balanced design reduces deflection for straighter holes and improves dust extraction efficiency when used with a compatible vacuum system.

Suitable for

• Drilling deep anchor holes in reinforced concrete
• Preparing rebar or dowel holes for structural connections
• Through‑holes in thick masonry and block walls
• Construction and renovation tasks requiring precise, long‑reach drilling

Key specifications

• Nominal diameter: 20 mm
• Working length (usable flute length): 600 mm
• Total length: 740 mm
• Shank type: SDS‑MAX compatible
• Material: carbide tipped cutting head with hardened steel body
• Intended materials: concrete, reinforced concrete, masonry

How to use

Install the bit into a hammer drill with an SDS‑MAX chuck following the drill manufacturer’s instructions and ensure the shank locks securely. Mark the drilling position, start at low speed to create a guide indent, then apply steady pressure and allow the hammer action of the tool to do the cutting. Periodically withdraw the bit to clear dust and debris from the hole, and use a vacuum or dust extraction adapter where possible to maintain visibility and reduce airborne dust. For drilling through reinforced concrete, advance carefully when encountering rebar and switch to a dedicated rebar‑drilling mode or use a cooling/lubrication method if recommended by the drill manufacturer.

Usage recommendations

Use the drill bit with compatible SDS‑MAX rotary hammers rated for the required impact energy. Wear appropriate personal protective equipment, including eye and hearing protection and a dust mask or respirator. For best results and longer tool life, avoid excessive side loads, keep the bit clean of packed dust, and match drilling speed and pressure to material hardness.
