Drill bit Bosch SDS+ 8.5 mm drill accessory, model 2608585605

Bosch SDS+ 8.5 mm drill bit (model 2608585605) is an SDS-plus shank accessory designed for rotary hammers that accept SDS+ tooling. With an 8.5 mm working diameter it is intended for drilling into concrete, masonry and similar hard substrates encountered in construction and renovation. The bit provides simple, fast insertion and removal in compatible SDS+ chucks and is made to match standard SDS+ rotational and percussion motion for efficient holemaking.

Advantages

The SDS+ design ensures secure engagement in rotary hammer chucks and reduces slippage during percussion drilling. The 8.5 mm diameter offers a balance between drilling speed and hole precision for common anchor, dowel and fixing applications. Compatibility with SDS+ systems simplifies bit changes on site and allows use with a wide range of Bosch and industry-standard SDS+ rotary hammers.

Suitable for

• Drilling anchor and fixing holes in concrete and reinforced concrete
• Creating holes in masonry, brick and cement block for dowels and plugs
• Renovation and construction tasks requiring an SDS+ rotary hammer
• Electrical and plumbing installations where through-holes in hard substrates are needed

Key specifications

• Shank type: SDS-plus shank compatible with SDS+ chucks
• Working diameter: 8.5 mm
• Intended materials: concrete, masonry, brick, cement-based substrates
• Tool application: rotary hammer drilling with percussion action

How to use

Insert the SDS+ shank into the rotary hammer chuck until it engages, following the tool manufacturer's instructions for secure locking. Select appropriate drilling speed and percussion mode for concrete or masonry, apply steady axial pressure and allow the tool's percussion action to advance the bit. Withdraw the bit occasionally to clear debris from the hole. Replace the bit when wear or reduced drilling performance is observed.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and dust mask when drilling into concrete or masonry. Choose correct drill diameter for anchors and plugs and consider pilot drilling or correct bit length to avoid over-penetration. For prolonged drilling tasks, allow periodic cooling and clear dust to maintain performance.
