Drill Bits Bosch CYL-3 6 mm Diameter 100 mm Length

The Bosch CYL-3 6 mm Diameter 100 mm Length drill bit is engineered for precision masonry drilling. Manufactured with a highly durable Bosch carbide blend, this 6 mm x 100 mm bit is designed to withstand repeated use in concrete and natural stone while maintaining drilling accuracy. The 2‑flute U‑shape geometry improves dust removal and reduces friction and heat, helping to extend tool life. Compatible with cylindrical shank systems, the bit fits corded and cordless impact drills and is suitable for creating holes for fixings in abrasive materials.

Advantages

The special Bosch carbide composition provides high wear resistance for prolonged service life when drilling concrete. The 2‑flute U‑shape design promotes efficient debris evacuation to lower friction and heat generation, which reduces wear on the cutting edges. Tight manufacturing tolerances ensure exact drilling and a secure hold of fixings in drilled holes. The cylindrical shank offers broad compatibility with standard impact drill chucks.

Suitable for

• Drilling holes for fixings in concrete
• Anchoring and fastening in natural stone
• Preparatory drilling for construction and renovation tasks
• Use with corded and cordless impact drills that accept cylindrical shanks

Key specifications

• Material tip: high‑durability carbide blend optimized for masonry
• Shank type: cylindrical shank compatible with standard chucks
• Flute design: 2‑flute U‑shape for improved dust removal
• Diameter: 6 mm
• Overall length: 100 mm
• Primary use: drilling in concrete and natural stone

How to use

Secure the drill bit in the drill chuck so the cylindrical shank is fully gripped. Start drilling at low speed to establish the hole, then increase speed as needed while maintaining steady pressure. For deeper holes, periodically withdraw the bit to clear dust and debris and allow cooling. Use appropriate personal protective equipment such as safety glasses and hearing protection when operating impact drills.

Usage recommendations

To maximise bit life and drilling accuracy, use the bit in impact drilling mode with steady, moderate feed pressure, avoid excessive side load, and clear dust regularly. For hard or reinforced concrete, use short drilling intervals to prevent overheating. Ensure the drill and bit are suitable for the material before starting the job.
