Bosch Expert SDS Max-8X Hammer Drill Bit 22 mm for Rotary Hammers

The Bosch Expert SDS Max-8X Hammer Drill Bit 22 mm for Rotary Hammers is engineered for heavy-duty drilling tasks in professional construction and renovation environments. Designed with a 2.2 cm diameter and a length of 520 mm, this hammer drill bit delivers reliable performance when working with demanding materials such as concrete, reinforced concrete, and stone. It is equipped with an advanced 4-cutter full carbide head made from a single piece of metal to prevent jamming and withstand heavy impact.

Advantages

This drill bit offers exceptional durability and longevity, significantly reducing accessory changes and downtime on the job site. The Bosch Carbide Technology ensures that the tip remains strong even when encountering rebar in reinforced concrete. The solid 4-cutter head design evenly distributes the workload, providing efficient material removal and consistent hole precision without structural weakness on impact.

Suitable for

• Drilling in concrete and reinforced concrete
• Drorying in stone
• Heavy-duty anchor installation
• Rebar extension projects
• Professional construction and renovation work

When it may not be suitable

This tool is not recommended for drilling in soft materials such as wood, drywall, or plastics, where a standard twist drill bit or specialized bit would be more appropriate. It is also not suitable for standard drills that do not accept SDS max shank connections.

Key specifications

• Drill bit type: Hammer drill bit
• Drill bit diameter: 2.2 cm
• Length: 520 mm
• Shank type: SDS max
• Head design: 4-cutter full carbide head
• Compatible materials: Concrete, stone, reinforced concrete

How to use

Ensure that the rotary hammer is switched off before inserting the drill bit securely into the SDS max chuck until it clicks into place. Align the drill bit perpendicularly to the target surface of concrete or stone. Apply steady, moderate pressure while letting the rotary hammer mechanism do the work. Avoid excessive lateral pressure to prevent binding or wear. Allow the bit to cool down periodically during prolonged drilling sessions.

What to consider before purchase

• Verify that your power tool is compatible with SDS max shanks before purchasing.
• Check the required hole diameter of 2.2 cm and length of 520 mm for your specific application.
• Confirm that the primary application involves hard masonry materials like concrete or reinforced concrete.

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses, ear protection, and a dust mask when operating rotary hammers. Inspect the carbide tip for wear before each use to ensure optimal drilling efficiency.
