Drill Bit AWTools SDS‑MAX 22 mm — length 600/740 mm, square shank, AWTools AW43835

SDS‑MAX 22 mm drill bit from AWTools with a square shank and two overall length options (600 mm and 740 mm) designed for use in SDS‑MAX rotary hammers. It is intended for drilling large diameter holes in masonry, concrete and natural stone, and for heavy‑duty tasks where an extended reach and a robust connection to the tool are required. The bit combines a durable working head with a reinforced shank to withstand the impacts and torque typical for demolition and construction work.

Advantages

The AWTools SDS‑MAX 22 mm bit provides reliable performance in demanding conditions thanks to its square shank that ensures secure coupling with compatible rotary hammers. Two available overall lengths give flexibility for both standard and deep drilling applications without the need for extensions. The bit is engineered for effective dust removal and controlled cutting in hard substrates, which helps maintain drilling speed and reduces wear. The reinforced construction improves resistance to bending and breakage during chiselling or heavy drilling.

Suitable for

• Drilling 22 mm diameter holes in concrete and reinforced concrete
• Creating openings in masonry, brick and natural stone
• Heavy‑duty anchor and dowel installation tasks
• Jobs requiring extended reach or deeper holes (600 mm and 740 mm lengths)
• Chiselling work when used with appropriate SDS‑MAX hammers

Key specifications

• Shank type: SDS‑MAX square shank for secure tool engagement
• Diameter: 22 mm suitable for medium‑to‑large anchors and dowels
• Overall lengths: 600 mm and 740 mm for standard and extended reach
• Material and construction: reinforced body and impact‑resistant head designed for hammer drilling and chiselling
• Application: masonry, concrete, reinforced concrete and natural stone

How to use

Select the appropriate overall length (600 mm or 740 mm) based on the required drilling depth and fit it into an SDS‑MAX compatible rotary hammer following the tool manufacturer's instructions. Mark and center the drilling location, start the hammer at low speed to create a guide, then increase power and apply steady axial pressure while allowing the hammer action to perform the work. Periodically withdraw the bit to clear debris and prevent clogging; for reinforced concrete, proceed slowly and avoid excessive lateral force. Wear appropriate personal protective equipment, including eye, ear and respiratory protection, and ensure the workpiece is secure.

Usage recommendations

Use the 600 mm length for most standard anchoring and drilling tasks; choose the 740 mm length when deeper holes or reach around obstacles are required. Match the drill bit to an SDS‑MAX rotary hammer with adequate impact energy for 22 mm drilling; inspect the shank and cutting head regularly for wear and replace the bit if deformation or excessive wear is observed to maintain safe and efficient operation.
