Hammer drill bit Bosch Expert SDS Max-8X, SDS-Max, 20 mm diameter, for rotary hammers

Bosch Expert SDS Max-8X is an SDS‑Max hammer drill bit designed for use in rotary hammers. With a 20 mm diameter and a full carbide head in a 4‑cutters geometry, this single-piece drill bit is intended for drilling into concrete and masonry with SDS‑Max chucks. The design targets professional construction and renovation tasks where compatibility with SDS‑Max rotary hammer drills and durable performance are required.

Advantages

The full carbide head and advanced 4‑cutter geometry provide increased wear resistance and stability under impact, reducing the frequency of bit changes. Compatibility with SDS‑Max chucks ensures secure seating and efficient power transfer from rotary hammers. The single-piece construction minimises weak points and potential jamming during heavy-duty drilling in concrete and reinforced concrete.

Suitable for

• Drilling holes in concrete for anchors and fixings
• Creating core holes in masonry and solid brickwork
• Installing rebar extensions or drilling around reinforcement
• General construction and renovation tasks using SDS‑Max rotary hammers

Key specifications

• Shank type: SDS‑Max compatible
• Nominal diameter: 20 mm
• Tip material: full carbide head
• Geometry: 4‑cutter design for impact resistance
• Quantity per pack: single piece
• Intended materials: concrete and masonry

How to use

Fit the Bosch Expert SDS Max-8X into an SDS‑Max rotary hammer chuck according to the tool manufacturer’s instructions until it locks securely. Use the appropriate hammer mode and select a drill speed and feed pressure suitable for concrete or masonry. Start drilling with steady, even pressure, allowing the tool and bit to remove material without excessive force. Withdraw the bit periodically to clear dust and debris and to cool the cutting edges when drilling deep holes.

Usage recommendations

Use the drill bit with rotary hammers rated for SDS‑Max accessories and wear appropriate personal protective equipment, including eye, hearing and respiratory protection. For reinforced concrete, advance drilling in stages and clear debris frequently to preserve the carbide tip. Replace the bit when cutting performance declines or when visible wear on the carbide head appears.
