Drill bit AWTools AW SDS‑MAX 40×600×740 mm square shank

AWTools AW SDS‑MAX 40×600×740 mm square shank is a rotary hammer drill bit designed for percussion drilling in concrete and masonry. With a 40 mm cutting diameter and a 600 mm working length, this SDS‑MAX bit provides deep-hole capability for heavy-duty construction and renovation tasks. The square shank ensures stable engagement with compatible SDS‑MAX chucks and reduces slippage during high-torque, high-impact operation.

Advantages

The SDS‑MAX geometry and robust carbide tip deliver efficient material removal and prolonged service life when drilling into reinforced concrete and masonry. The 600 mm working length allows deep anchoring and through‑drilling without frequent bit changes, while the 740 mm overall length offers extra reach for overhead or recessed drilling. The square shank design provides reliable retention in SDS‑MAX rotary hammers and simplifies bit replacement under jobsite conditions.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Through‑drilling and deep boreholes in masonry
• Heavy demolition and renovation requiring large‑diameter percussion drilling
• Installation of utility lines, plumbing and HVAC passages through walls and floors

Key specifications

• Cutting diameter: 40 mm
• Working length: 600 mm
• Overall length: 740 mm
• Shank type: square SDS‑MAX compatible
• Intended material: concrete, reinforced concrete, masonry
• Application: percussion/rotary hammer drilling

How to use

Select a rotary hammer with an SDS‑MAX chuck rated for bits of this diameter and length. Mark the drilling position, secure the work area, and use appropriate personal protective equipment including eye, ear and respiratory protection. Insert the square shank fully into the SDS‑MAX chuck until it locks. Start drilling at low speed to establish the hole, then apply steady axial pressure while operating the hammer function for effective percussion action. Withdraw the bit periodically to clear dust and debris, and allow the tool to cool during prolonged use.

Usage recommendations

Use with a rotary hammer that matches SDS‑MAX specifications and is capable of delivering sufficient impact energy for 40 mm concrete drilling. Combine drilling with compressed-air or vacuum dust extraction where possible to reduce dust exposure. For best results in reinforced concrete, proceed slowly when encountering rebar and use rebar cutters if necessary.
