Vrták Bosch SDS Plus-5X 12 mm priemer × 550 mm dĺžka, model 2608836620

Bosch SDS Plus-5X 12 mm × 550 mm drill bit is engineered for deep and accurate drilling in concrete, masonry and natural stone with SDS Plus rotary hammers. Its extended 550 mm length enables through-holes and anchor drilling where greater reach is necessary while maintaining compatibility with SDS Plus chucks. The design focuses on stable guidance and consistent chip removal to support long drilling depths and repeatable results on construction and renovation sites.

Advantages

The SDS Plus-5X geometry and flute design combine to improve dust extraction and reduce clogging during long holes. A reinforced shank and optimized head shape deliver reliable bite and precise centring in hard materials. The 12 mm diameter provides a balance between hole clearance and structural strength of the bit, allowing stable drilling even at increased lengths. The bit is designed for plug-in use with standard SDS Plus rotary hammers and offers consistent performance over extended drilling tasks.

Suitable for

• Drilling deep through-holes in concrete and masonry
• Installing anchor bolts and rebar dowels requiring extended reach
• Renovation and construction tasks with hard stone or block walls
• Professional use where long-reach drilling and reliable chip removal are required

Key specifications

• Diameter: 12 mm
• Overall length: 550 mm
• Shank type: SDS Plus compatible
• Primary application: Concrete, masonry, natural stone
• Drill geometry: Long-reach flute design for improved chip removal

How to use

Fit the drill bit into an SDS Plus rotary hammer according to the tool manufacturer’s instructions, ensuring the shank locks securely in the chuck. Mark the drilling point and use a steady, controlled feed pressure; allow the hammer action to perform the cutting rather than forcing the bit. For deep holes, periodically withdraw the bit to clear dust and debris and to avoid overheating. Use appropriate personal protective equipment including eye, ear and dust protection and follow site safety rules.

Recommendations

For best results in long drilling tasks, use the bit with a rotary hammer that matches the SDS Plus system and select a moderate rotational speed with full hammer action. When drilling reinforced concrete, inspect for rebar and adapt technique; if contact with metal is frequent, check the bit regularly for wear and replace when dull to maintain hole quality.
