Drill Bit Bosch CYL-3 — diameter 12 mm, length 150 mm, single piece

Bosch CYL-3 drill bit, 12 mm diameter and 150 mm overall length, is a single-piece carbide/steel bit designed for rotary and percussion drilling. Made with a Bosch-developed carbide blend, the bit is intended for drilling holes for fixings in abrasive materials such as concrete and natural stone. Its two-flute U-shaped geometry improves dust removal and reduces friction and heat, supporting consistent hole quality and extended tool life when used in compatible impact or rotary drills with cylindrical shank systems.

Advantages

The specially developed carbide blend increases wear resistance and maintains cutting performance during repeated use in abrasive substrates. The effective two-flute U-shape design facilitates rapid debris evacuation, reducing bit clogging and heat build-up. Compatibility with cylindrical shank systems makes the bit suitable for corded and cordless impact drills. The product has been tested to meet masonry drill bit board tolerances, supporting precise drilling and reliable fixing retention.

Suitable for

• Drilling holes for fixings in concrete
• Creating anchor and dowel holes in natural stone
• General rotary drilling tasks in construction where a carbide masonry bit is required

Key specifications

• Drill diameter: 12 mm
• Overall length: 150 mm
• Construction: single-piece carbide/steel body
• Tip/geometry: two-flute U-shaped cutting geometry for efficient dust removal
• Shank type: cylindrical shank compatible with standard chucks and holders
• Best use: designed for abrasive materials such as concrete and natural stone

How to use

Select an appropriate drill with a compatible cylindrical chuck and secure the Bosch CYL-3 bit firmly. For masonry applications, use the hammer/impact mode if available, applying steady feed pressure without excessive force. Start at low speed to establish the hole, then increase to the recommended drilling speed for the material and tool. Periodically withdraw the bit to clear debris and allow cooling; avoid prolonged continuous operation at maximum speed to reduce wear and overheating.

Usage recommendations

Use suitable personal protective equipment (safety glasses, dust mask and hearing protection) when drilling. Match drill speed and feed to the substrate — lower speeds and steady pressure for harder stone or reinforced concrete. Replace the bit when wear reduces cutting efficiency or hole precision. Store the bit dry and protected to avoid damage to the cutting edges.
