Drill bit AWTools SDS‑MAX 22 x 800 x 940 mm, AWTools AW43737

SDS‑MAX 22 x 800 x 940 mm drill bit by AWTools is designed for deep-hole drilling in concrete, masonry and natural stone with SDS‑MAX rotary hammers. The 22 mm cutting diameter and 800 mm working length allow efficient creation of anchor holes, rebar clearance and through-holes in structural and renovation work. The robust shank and flute geometry provide chip evacuation for longer uninterrupted drilling runs in demanding materials.

Advantages

The AWTools SDS‑MAX bit combines a long working length with a durable design suitable for repeated use in construction environments. Its 22 mm diameter delivers precise holes for anchors and fixings while the optimized flute profile facilitates efficient dust and debris removal. The bit is compatible with SDS‑MAX rotary hammers, enabling rotary and percussion action for fast penetration in hard substrates.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Creating through-holes for pipes and conduits in masonry
• Clearing around protruding rebar during demolition or retrofit
• Deep-hole drilling for structural fastenings and fixings

Key specifications

• Cutting diameter: 22 mm
• Working length: 800 mm
• Overall length: 940 mm
• Mount type: SDS‑MAX shank for rotary hammers
• Intended materials: concrete, masonry, natural stone
• Function: rotary-percussion deep drilling

How to use

Secure the SDS‑MAX bit into a compatible rotary hammer according to the tool manufacturer's instructions. Mark the drilling point and start at low speed to establish the hole, then apply steady pressure and use the hammering function for effective penetration. Periodically withdraw the bit to clear dust and allow the bit to cool; for long deep holes, withdraw more frequently to maintain chip removal and reduce wear. Ensure proper personal protective equipment and dust extraction or wet suppression when drilling.

Usage recommendations

Use the AWTools SDS‑MAX 22 x 800 x 940 mm bit with a rotary hammer rated for long-reach drilling and follow recommended feed pressure—avoid excessive side loads. For reinforced concrete, inspect holes for rebar and consider using carbide-tipped or specialized rebar-cutting accessories if frequent contact with reinforcement is expected. Maintain the bit by cleaning flutes after use and store it in a dry place to prevent corrosion.
