Product
The Bosch S4 SDS+ 7mm drill bit is engineered for precise drilling in reinforced concrete, masonry, and hard granite. Designed for SDS+ rotary hammers, it provides reliable performance in demanding construction and renovation tasks.
Specifications
- 4-flute helix ensures fast dust removal and maintains drilling speed
- Advanced carbide cutting edge geometry increases lifespan and improves force transmission
- Made from high-alloy steel with optimized hardening for abrasion resistance
- Active centering tip prevents wandering and ensures accurate hole positioning
- Suitable for drilling through concrete with rebar, stone, and similar tough materials
Usage
Attach the bit to an SDS+ compatible rotary hammer. Ideal for fast, clean drilling in reinforced concrete, stone, or masonry. For bits 460mm or longer, begin with a 150mm deep pilot hole using the same diameter for optimal accuracy and efficiency.
FAQ
-
What materials can this drill bit handle?
It is suitable for reinforced concrete, masonry, natural stone, and hard granite.
-
What drilling machines are compatible?
Compatible with all rotary hammers that accept SDS+ shank drill bits.
-
What are the benefits of the 4-flute design?
The quadruple flute improves dust extraction, keeps the drill faster, and reduces bit wear.
-
Can it be used for rebar?
Yes, the carbide cutting edges are designed to drill through concrete with embedded rebar.
-
What is the recommended technique for deep holes?
For bits 460mm or longer, create a 150mm deep pilot hole with a bit of identical diameter before proceeding with the full-length bit.
