Broca Bosch CYL-9 MultiConstruction 16 x 150 x 200 mm EXPERT

Bosch CYL-9 MultiConstruction 16 x 150 x 200 mm EXPERT is a drill bit designed for mixed-material applications where concrete, masonry and brick surfaces must be penetrated reliably. With a 16 mm diameter, 150 mm usable length and 200 mm overall length, this tool is intended for use in hammer drills with SDS-plus chucks and is suitable for both professional and advanced DIY tasks. The CYL-9 geometry balances drilling stability and chip removal to maintain consistent performance in multi-material environments.

Advantages

The CYL-9 MultiConstruction bit provides stable drilling in combined materials thanks to its optimized tip geometry and flute design that improve impact transfer and debris evacuation. The 150 mm usable length allows for deeper holes while the 200 mm overall length gives secure clamping in SDS-plus chucks. Compatible with hammer drilling action, the bit is produced to meet the durability expectations of the EXPERT line, offering a predictable drilling experience in a range of common building substrates.

Suitable for

• Drilling holes in concrete for anchors and through-fixing where mixed substrates are present
• Work in masonry and brick walls requiring hammer drilling
• Professional installation tasks and heavy-duty DIY projects using SDS-plus hammer drills
• Prepping openings for fasteners, dowels or sleeves in renovation and construction

When it may not be suitable

This drill bit is optimized for hammer drilling into concrete, masonry and brick; it may not be ideal for precision drilling in soft materials such as wood, plastic or thin metal where a conventional twist or wood bit would provide better finish and accuracy. It is also not intended for use in rotary-only handheld drills without hammer action when efficient drilling in hard masonry is required.

Key specifications

• Diameter: 16 mm
• Usable length (working length): 150 mm
• Overall length: 200 mm
• Shank type: SDS-plus compatible
• Application: MultiConstruction (concrete, masonry, brick)
• Recommended drill type: hammer drill with SDS-plus chuck

How to use

Install the bit into an SDS-plus hammer drill according to the drill manufacturer's instructions, ensuring the bit locks securely in the chuck. Mark the drilling position, use appropriate personal protective equipment (safety glasses, gloves, dust mask), and start drilling with moderate pressure to allow the hammer action to work effectively. For deep holes, periodically withdraw the bit to clear dust and debris and reduce heat build-up. When drilling into reinforced concrete, proceed slowly and avoid excessive lateral force.

What to consider before purchase

• Ensure your drill has an SDS-plus chuck and hammer function
• Confirm the 16 mm diameter and 150 mm usable length match the required hole size and depth
• Verify the bit is intended for mixed masonry/concrete applications rather than wood or metal

Recommendations

For consistent results, use the bit with the correct hammer drill settings, allow the tool to do the work without excessive force, and clear debris regularly. For through-holes or deep anchor installations, check alignment and hole depth periodically and replace the bit if wear reduces cutting efficiency.
