Drill bit set Bosch CYL-3, 150 mm length, model 2608597666

Bosch CYL-3 drill bits with a 150 mm length are engineered for drilling holes in concrete and other abrasive masonry materials where extended reach is required. The CYL-3 design combines a high-durability carbide tip with a 2-flute U-shaped profile to ensure efficient dust evacuation and accurate drilling. These bits are intended for use with cylindrical shank systems on corded or cordless impact drills and are suitable for tasks such as creating fixing points and anchor holes in construction and renovation work.

Advantages

The specially developed Bosch carbide blend offers high wear resistance for repeated drilling in concrete and natural stone, extending service life under heavy use. The 2-flute U-shaped geometry improves dust removal from the hole, reduces friction and heat buildup, and helps maintain drill accuracy over time. Compatibility with cylindrical shank systems provides easy fitment in a wide range of impact drills, and compliance with the masonry drill bit association test mark confirms consistent tolerances and reliable fixing retention.

Suitable for

• Drilling fixing and anchor holes in concrete
• Creating holes in natural stone and other abrasive masonry
• Construction, renovation and maintenance tasks requiring 150 mm reach
• Use with corded or cordless impact drills equipped with cylindrical shanks

Key specifications

• Tip material: high-durability carbide blend optimized for masonry
• Flute design: 2-flute U-shaped profile for efficient dust removal
• Applicable materials: concrete, natural stone and other abrasive masonry
• Shank type: cylindrical shank for compatibility with standard chucks
• Intended tool type: corded and cordless impact drills

How to use

Select a drill with a compatible cylindrical chuck and secure the CYL-3 bit firmly. Mark the drilling location, start at low speed to position the tip accurately, then apply steady pressure with the impact function engaged for concrete and masonry. Periodically withdraw the bit to clear accumulated dust and allow cooling, especially during prolonged or deep drilling. Follow the drill manufacturer's recommendations for speed and feed when working in different materials.

Usage recommendations

For best results, use the Bosch CYL-3 150 mm drill bit with an impact drill and appropriate personal protective equipment. Avoid excessive side loads and intermittent operation to minimise wear. If drilling multiple deep holes, allow the bit to cool and clear dust regularly to maintain cutting performance and extend service life.
