Drill bit Bosch 2 608 585 624, twist drill, length 210 mm

Bosch drill bit 2 608 585 624 is a 210 mm long twist drill designed for deep drilling in masonry, concrete and reinforced concrete. Manufactured by Bosch for use with SDS-plus rotary hammers, this replacement or accessory bit provides the length necessary for through-holes and deeper anchor or rebar tasks. The fluted twist geometry and robust carbide tip are engineered to maintain drilling performance and to clear dust from the bore while working in heavy-duty building materials.

Advantages

The 210 mm length allows consistent drilling to a fixed depth without repeated repositioning. Compatibility with SDS-plus rotary hammers ensures secure mounting and efficient power transfer during impact rotation. The combination of twist flutes and a carbide cutting head improves penetration in masonry and concrete while enhancing bit life under frequent use. The design facilitates effective debris removal from the hole, reducing load on the drill and improving drilling stability.

Suitable for

• Drilling anchor and fixing holes in masonry walls
• Creating through-holes for pipes and conduits in concrete
• Drilling into reinforced concrete for rebar tie points and fasteners
• Use on construction, renovation and installation tasks requiring a 210 mm drilling depth

Key specifications

• Overall length: 210 mm
• Drill type: twist drill with fluted design
• Tip material: carbide-tipped for masonry and concrete
• Shank system: SDS-plus compatible
• Intended materials: masonry, concrete, reinforced concrete

How to use

Install the bit into an SDS-plus rotary hammer according to the tool manufacturer's instructions, ensuring it locks securely. Mark the drilling point and, if necessary, use a centre punch or pilot mark to stabilize the bit at start. Begin drilling at low speed to establish the hole, then apply steady pressure and maintain the hammer action suited for masonry work. Periodically retract the bit to clear dust and debris from the bore; for deeper holes, remove accumulated dust frequently to preserve cutting efficiency and prevent jamming.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, dust mask and hearing protection. Use proper drilling speed and hammer mode settings recommended for your rotary hammer and the material being drilled. For reinforced concrete, proceed with controlled pressure to avoid premature wear on the carbide tip and clear the hole regularly to maintain drilling performance.
