Hammer drill bit Bosch 2 608 833 808 1.2 cm

The Bosch 2 608 833 808 1.2 cm hammer drill bit is an SDS plus-5X accessory engineered for rotary hammers. With a 1.2 cm diameter, it is intended for drilling into hard materials such as reinforced concrete and masonry. The bit combines a turn-angle head, a 4-flute design and a centring tip to enable fast dust evacuation, accurate hole positioning from the start and stable fixation of anchors and fixings.

Advantages

The turn-angle head and four-flute geometry increase drilling speed by improving dust removal and reducing wear on the cutting edges. The centring tip supports immediate, stable contact and precise hole diameters, while the SDS plus-5X design ensures compatibility with SDS-plus rotary hammers and firm tool engagement. The product is manufactured to PGM masonry drill bit association tolerances, which supports consistent hole quality and reliable hold of fixings.

Suitable for

• Drilling holes in reinforced concrete and structural masonry
• Installing anchors, bolts and fixings in hard substrates
• Professional construction and renovation tasks requiring repeatable hole accuracy
• DIY projects involving heavy-duty drilling with SDS-plus rotary hammers

Key specifications

• Shank system: SDS-plus (SDS plus-5X geometry)
• Diameter: 1.2 cm
• Tip: centring tip for guided start and precise hole position
• Flutes: 4-flute design for efficient dust removal
• Recommended material: reinforced concrete, masonry and other hard substrates
• Quality standard: manufactured to strict masonry drill bit tolerances (PGM)

How to use

Install the drill bit into the SDS-plus chuck of a compatible rotary hammer until it locks. Select the hammer or rotary-hammer mode appropriate for the substrate and set a controlled feed force to avoid excessive pressure. Begin drilling at low speed to allow the centring tip to establish the hole position, then continue with normal hammering speed. Withdraw the bit periodically to clear dust and debris from the hole and flutes to maintain drilling efficiency and prevent overheating.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask and gloves) and ensure the workpiece is stable. Match the drill bit diameter to the anchoring system specified for your fixings. For deep or large-diameter holes, drill in stages and remove debris frequently. Store the bit in a dry place to preserve cutting performance.
