Drill Bit Bosch SDS plus-7X 7 mm Diameter 165 mm Length

The Bosch SDS plus-7X drill bit is a high-performance accessory engineered specifically for rotary hammer drills. With a diameter of 7 mm and a total length of 165 mm, this tool is designed to handle the most demanding drilling tasks in masonry and concrete. It utilizes advanced carbide technology to ensure consistent results and extended service life, even when encountering challenging materials like reinforced concrete.

Advantages

This drill bit features a robust 4-cutter full carbide head that prevents jamming when hitting rebar, significantly reducing the risk of breakage compared to standard two-cutter bits. The integration of Bosch Carbide Technology and a highly resistant welding process ensures that the tip remains securely attached under heavy impact. Users benefit from increased efficiency and durability, as this bit is designed to last up to three times longer than conventional alternatives, making it a reliable choice for professional construction environments.

Suitable for

• Drilling into cured concrete
• Working with hardened reinforced concrete
• Boring holes in hard natural stone such as granite and gneiss
• Professional installation and fixing tasks

When it may not be suitable

This drill bit is specifically optimized for rotary hammers with an SDS plus chuck system and is not compatible with standard drill chucks. It is not intended for use on wood, metal, or soft materials, as the carbide head design is strictly engineered for masonry and concrete applications.

Key specifications

• Diameter: 7 mm
• Working length: 165 mm
• Shank type: SDS plus
• Head design: 4-cutter full carbide

How to use

Insert the drill bit into the SDS plus chuck of your rotary hammer until it clicks into place. Ensure the tool is set to the hammer-drilling mode. Apply steady, consistent pressure while drilling, allowing the carbide head to do the work. Avoid excessive force, which can cause unnecessary heat buildup. After drilling, allow the bit to cool down before touching it, as it may become hot during operation.

What to consider before purchase

• Verify that your power tool is equipped with an SDS plus chuck system.
• Ensure the 7 mm diameter matches the requirements of your specific anchors or fixings.
• Confirm that the 165 mm length is sufficient for the depth of the holes you intend to drill.

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and hearing protection, when operating a rotary hammer. Regularly inspect the drill bit for signs of wear or damage to maintain optimal performance and safety.
