Vrták Bosch SDS plus-7X 12 x 950 x 1000 mm

Bosch SDS plus-7X 12 x 950 x 1000 mm is a long-reach SDS‑plus rotary hammer drill bit engineered for drilling deep holes in concrete, masonry and comparable base materials. With a 12 mm diameter and a 950 mm working length, the bit provides extended reach while maintaining efficient dust removal and reliable impact transfer when used with SDS‑plus rotary hammers. The design supports professional and construction applications that require drilling through thick structural elements or for installing long anchors and dowels.

Advantages

The SDS plus-7X geometry and flute profile are optimized for faster drilling progress and effective evacuation of drilling debris along the extended working length. The carbide tip delivers wear resistance and consistent centring, while the SDS‑plus shank ensures secure tool engagement and easy insertion/removal in compatible rotary hammers. The rigid shaft resists bending during deep drilling operations and maintains alignment for accurate hole placement.

Suitable for

• Drilling long through-holes in concrete and reinforced concrete
• Making deep anchor and dowel holes for fixings
• Core work on masonry walls and structural elements
• Professional construction, renovation and installation tasks requiring extended reach

Key specifications

• Shank type: SDS‑plus compatible
• Cutting diameter: 12 mm
• Working length: 950 mm
• Overall length: 1000 mm
• Tip material: tungsten carbide cutting head
• Flute type: spiral flute designed for efficient dust removal
• Intended material: concrete, masonry and similar mineral substrates

How to use

Install the drill bit into an SDS‑plus rotary hammer according to the tool manufacturer’s instructions, ensuring the bit is fully seated and locked. Select the rotary hammer’s hammer-drilling mode and start at low speed to position the tip, then apply steady, moderate pressure while allowing the tool’s impact action to provide the drilling force. Periodically withdraw the bit to clear accumulated dust and improve cooling when drilling deep holes. Use appropriate personal protective equipment — eye protection, hearing protection and dust mask — and follow safe working practices on site.

Recommendations

For best results in reinforced concrete, use progressive drilling technique: begin with light feed to center the carbide tip, then increase feed rate while monitoring bit temperature and debris evacuation. Avoid excessive side loads and bending; use guides or supports for very deep or precision holes.
