Drill Bosch Expert CYL-9 MultiConstruction 8 mm × 250 mm, carbide-tipped SDS-plus compatible

The Bosch Expert CYL-9 MultiConstruction drill bit, 8 mm × 250 mm, is designed for drilling deeper holes in concrete, masonry and other common construction materials. The carbide-tipped cutting head provides enhanced wear resistance and maintains cutting performance over prolonged use. This SDS-plus compatible drill is intended for use with rotary hammers that accept SDS-plus shanks, offering reliable penetration and dimensional stability when drilling to greater depths.

Advantages

The carbide-tipped head increases life span and ensures consistent cutting performance in abrasive materials. The CYL-9 geometry is optimized to reduce bit wandering at start and to maintain concentricity during extended drilling, which improves hole accuracy. SDS-plus compatibility allows quick, secure insertion and reliable transmission of hammering force from the tool to the bit. The 250 mm overall length enables drilling deeper holes than standard lengths without additional extensions.

Suitable for

• Drilling holes in concrete for anchors and through-fixing
• Creating openings in masonry and brickwork for installations
• Drilling deeper holes for renovation and structural tasks
• Use with SDS-plus rotary hammers on construction and installation sites

Key specifications

• Diameter: 8 mm
• Total length: 250 mm
• Tip material: carbide-tipped cutting head
• Shank type: SDS-plus compatible
• Intended materials: concrete, masonry, brick and other construction materials

How to use

Install the drill bit into an SDS-plus rotary hammer according to the tool manufacturer's instructions, ensuring the shank locks securely in the chuck. Use rotary hammer mode with percussion enabled for concrete and masonry. Apply steady axial pressure without forcing the bit; allow the hammer action and carbide tip to do the cutting. Withdraw the bit periodically to remove debris and reduce heat buildup when drilling deep holes. After use, clean and store the bit in a dry place to prevent damage.

Recommendations

For best results, use the Bosch Expert CYL-9 MultiConstruction bit at the recommended rotation and impact settings for your rotary hammer and match the bit diameter to the appropriate anchor or fixing. Wear appropriate personal protective equipment such as eye protection, hearing protection and dust mask when drilling. Replace the bit if the tip shows significant wear or if drilling performance deteriorates.
