Drill Bit AWTools AW SDS MAX 38 x 460 x 600 mm

AWTools SDS MAX drill bit 38 x 460 x 600 mm is a heavy-duty accessory designed for use with SDS MAX rotary hammers. It is engineered to drill large-diameter holes in concrete, masonry and natural stone. The bit’s 38 mm diameter combined with a 460 mm working flute length and 600 mm overall length enables deeper drilling for through-holes, anchor installation and utility penetrations on construction sites and renovation projects.

Advantages

The SDS MAX shank ensures secure tool retention and fast bit changes on compatible rotary hammers. A robust carbide tip and reinforced flute profile provide effective dust evacuation and stable drilling performance in hard materials. The extended working length reduces the need for extensions when creating deep holes, while the solid construction improves resistance to bending and wear during repeated use.

Suitable for

• Drilling large-diameter holes in concrete and reinforced concrete
• Creating anchor and fixing points for structural and non-structural fasteners
• Installing utilities and pipelines that require deep through-holes
• Masonry and natural stone drilling where a long-reach bit is necessary

Key specifications

• Shank type: SDS MAX compatible
• Diameter: 38 mm
• Working flute length: 460 mm
• Overall length: 600 mm
• Tip material: carbide cutting tip for hard materials
• Application: concrete, reinforced concrete, masonry, natural stone

How to use

Secure the drill bit into the SDS MAX chuck of a compatible rotary hammer according to the tool manufacturer’s instructions. Use the appropriate hammer drilling mode and select a steady, controlled feed force. Start drilling at low speed to create a guide recess, then maintain consistent pressure while allowing the hammer action to advance the bit. Periodically withdraw the bit to clear accumulated dust from the hole and cooling airflow, especially when drilling deep holes. Follow safety guidelines including eye protection, hearing protection and dust control measures.

Usage recommendations

For best results use in SDS MAX rotary hammers rated for large-diameter drilling and match drilling speed and feed to material hardness. When drilling reinforced concrete, avoid excessive lateral force; allow the carbide tip to break through reinforcement gradually. Consider using dust extraction or wet drilling methods where permitted to minimise airborne silica dust.
