Drill bits Bosch CYL-3, length 200 mm, set/individual (model 2608597682)

Bosch CYL-3 drill bits, length 200 mm, are engineered for extended-reach drilling tasks in concrete, natural stone and similar abrasive materials. Manufactured with a durable Bosch carbide blend and a 2-flute U-shaped geometry, these bits are intended for creating clean, precise holes for fixings while optimising dust extraction and reducing heat and friction. The cylindrical shank design is compatible with standard chucks on corded and cordless impact drills, making the bit suitable for professional and DIY situations where deep or hard-to-reach drilling is required.

Advantages

The specially developed Bosch carbide compound provides high wear resistance for repeated drilling in concrete and other abrasive substrates, extending tool lifetime. The effective 2-flute U-shape improves dust evacuation from the hole, which reduces friction, lowers heat generation and helps maintain drilling speed and accuracy. Compliance with the PGM Masonry Drill Bit Association Board test mark ensures tight tolerances and consistent hole quality for reliable fixing retention. The cylindrical shank allows easy mounting in compatible chucks on both corded and cordless impact drills.

Suitable for

• Drilling holes for fixings in concrete and natural stone
• Deep-hole drilling and work in confined or hard-to-reach spaces
• Applications requiring extended-reach drill bits with cylindrical shank systems
• Use with compatible corded or cordless impact drills

How to use

Install the Bosch CYL-3 200 mm drill bit in a compatible chuck and tighten securely before operation. Use an appropriate impact drill setting for masonry drilling and apply steady, even pressure; avoid excessive side load to prevent bit breakage. For deep-hole work, periodically withdraw the bit to clear debris and maintain dust evacuation through the U-shaped flutes. Allow the bit to cool under continuous heavy use to preserve the carbide tip and maintain accuracy.

Usage recommendations

For best results when drilling into concrete or natural stone, use with a hammer/impact drill and appropriate PPE (safety glasses, dust mask and hearing protection). Match drill speed and feed pressure to the substrate hardness and withdraw the bit occasionally to clear dust. Store the bit dry and protected to prevent corrosion and preserve the carbide tip.
