Kiviporanterä Bosch 5 mm, malli 2 608 833 772, yksittäinen poravasaralle

Bosch hammer drill bit Ø5 mm, single-piece design for rotary hammers, is intended for drilling in concrete, masonry and natural stone. The SDS plus-compatible shank provides secure fitting in compatible rotary hammer chucks. The 4‑flute geometry with a turn‑angle head improves dust evacuation and increases penetration speed while a centring tip ensures accurate hole positioning from the start. The bit is designed for light to medium hammer drilling tasks in construction and renovation and meets tight manufacturing tolerances for consistent hole diameters.

Advantages

The 4‑flute design accelerates dust removal from the hole, reducing friction and wear on the cutting edge. The turn‑angle head enhances drilling speed and helps maintain bit lifetime under repeated hammering. A centring tip provides reliable guidance at drill start, producing exact hole diameters and improving the fit of anchors and fixings. Manufactured to strict tolerance standards, the bit offers predictable performance and compatibility with SDS plus rotary hammers.

Suitable for

• Drilling Ø5 mm holes in reinforced concrete
• Masonry and natural stone drilling tasks
• Installing anchors, plugs and fixings
• Light to medium duty construction and renovation work

Key specifications

• Diameter: 5 mm
• Shank type: SDS plus compatible
• Construction: single-piece masonry drill bit
• Tip: centring tip for accurate start
• Flute design: 4‑flute geometry for improved dust removal
• Head: turn‑angle cutting head for faster drilling
• Typical use: hammer drilling in concrete, stone and masonry

How to use

Select an SDS plus rotary hammer and secure the drill bit by inserting the shank into the chuck until it locks. Mark the drilling location, apply moderate pressure and start the hammer drilling mode. Allow the tool’s hammer action and the bit’s geometry to remove material; withdraw periodically to clear debris if necessary. Use steady, controlled feed and avoid excessive lateral force to maintain hole accuracy and extend bit life.

Recommendations

For best results when drilling into reinforced concrete, use the hammer function of the rotary hammer and match drilling speed and pressure to the material hardness. Regularly clear dust from the hole and replace the bit when wear affects centring or cutting performance to ensure secure anchor seating.
