Drill bit AWTools AW43777 SDS Max 40 x 800 mm

AWTools AW43777 SDS Max 40 x 800 mm is a heavy-duty drill bit designed for rotary and hammer drilling in concrete and masonry. With a 40 mm cutting diameter and an overall length of 800 mm, this bit is intended for creating larger anchor, conduit and service openings where depth and stability are required. The SDS Max shank provides a secure connection to compatible rotary hammers and allows efficient transfer of impact energy for reliable penetration in reinforced and non-reinforced substrates.

Advantages

The 40 mm diameter and extended 800 mm length enable deep, precise holes for anchors and pipe runs without frequent repositioning. The SDS Max shank ensures quick, secure mounting and reduced slippage during heavy-duty hammering. The bit's geometry is engineered for balanced rotation and effective removal of debris to maintain drilling speed in concrete and masonry. Materials and construction focus on durability under repeated impact and high torque conditions.

Suitable for

• Drilling large-diameter anchor holes in concrete and reinforced concrete
• Creating openings for electrical conduits, plumbing and HVAC penetrations
• Installation and renovation tasks requiring deep holes in masonry
• Construction work with SDS Max rotary hammers for heavy-duty drilling

Key specifications

• Cutting diameter: 40 mm
• Overall length: 800 mm
• Shank type: SDS Max
• Intended use: Rotary and hammer drilling in concrete and masonry

How to use

Install the bit securely into an SDS Max compatible rotary hammer according to the tool manufacturer's instructions. Mark the drilling point, start at low speed to establish a pilot position, then apply steady pressure while operating the hammer function for efficient penetration. Periodically withdraw the bit to clear dust and debris and to prevent overheating. For long runs, use appropriate support or guide to maintain alignment and reduce bending stress on the bit.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust control. Match drill speed and hammer settings to material hardness and consider using water suppression or a dust extraction system where applicable to reduce airborne dust. For drilling near rebar, proceed with caution and reduce feed pressure to avoid abrupt change in torque that could damage the bit or tool.
