Rotary hammer drill bit Bosch Expert SDS Clean plus-8X 12 mm working length 200 mm

Rotary hammer drill bit Bosch Expert SDS Clean plus-8X 12 mm working length 200 mm is a carbide-tipped drilling accessory designed for use with SDS chuck systems in rotary hammer tools. It is intended for creating precise 12 mm diameter holes at an extended depth of 200 mm in concrete, masonry and other mineral substrates. The Clean plus-8X geometry and flute design support efficient chip removal and stable drilling performance under repeated use.

Advantages

The drill bit offers a reinforced tip geometry and wear-resistant carbide for consistent penetration in hard materials while maintaining hole accuracy. Its flute profile promotes efficient removal of dust and debris from the hole, reducing clogging and heat buildup. The SDS shank provides secure connection with compatible rotary hammers, enabling reliable power transfer and reduced slippage during heavy-duty drilling tasks.

Suitable for

• Drilling 12 mm diameter holes in concrete and masonry
• Installing anchors, dowels and fixings at up to 200 mm depth
• Professional construction and renovation work where extended-depth holes are required
• DIY projects that require precise deep drilling in mineral substrates

Key specifications

• Diameter: 12 mm
• Working length: 200 mm
• Shank type: SDS-compatible
• Tip material: carbide (wear-resistant)
• Intended materials: concrete, masonry and similar mineral substrates
• Flute design: enhanced for chip and dust evacuation

How to use

Install the Bosch Expert SDS Clean plus-8X drill bit into the rotary hammer’s SDS chuck until it locks into place. Select the hammer-drill mode on the tool when penetrating concrete or masonry. Position the bit perpendicular to the work surface and start drilling at low speed to establish the hole, then apply steady pressure while allowing the tool to do the work. Withdraw the bit periodically to clear accumulated dust and debris for sustained performance and to reach the full 200 mm working depth as required.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask. For cleaner work and longer tool life, use a dust extraction system or periodically remove dust from the hole. Match the drill speed and hammer settings to the material density and avoid excessive lateral force to prevent premature wear or breakage.
