Bosch CYL-5 Concrete Drill Bit 8x250 mm

The Bosch CYL-5 concrete drill bit, measuring 8 mm in diameter and 250 mm in length, is a professional-grade tool engineered for high-performance drilling in concrete, masonry, and natural stone. This drill bit features a robust carbide tip designed to withstand the rigors of heavy-duty applications, ensuring consistent results and structural integrity during operation. The optimized flute geometry facilitates rapid dust removal, which prevents clogging and reduces heat buildup, thereby extending the overall service life of the tool.

Advantages

This drill bit offers exceptional durability and precision due to its high-quality carbide composition. The specialized design allows for efficient material extraction, which significantly increases drilling speed and reduces the physical strain on both the tool and the operator. Its compatibility with standard rotary hammers and impact drills makes it a versatile addition to any professional toolkit, providing reliable performance across various hard building materials.

Suitable for

• Drilling into concrete walls and floors
• Working with masonry and brickwork
• Boring holes in natural and artificial stone
• Professional construction and renovation projects

When it may not be suitable

This drill bit is not intended for use on metal, wood, or ceramic tiles, as the carbide tip geometry is specifically optimized for abrasive mineral materials. Using it on inappropriate surfaces may result in premature wear of the tip or damage to the workpiece.

Key specifications

• Diameter: 8 mm
• Total length: 250 mm
• Material: Carbide-tipped steel
• Compatibility: Rotary hammers and impact drills

How to use

To achieve the best results, ensure the drill bit is securely fastened into the chuck of your rotary hammer or impact drill. Position the tip of the drill bit against the marked spot on the surface and apply steady, moderate pressure. It is recommended to use a hammer action setting if the tool supports it for concrete drilling. Maintain a straight angle to the surface to prevent the bit from wandering or binding. Periodically retract the bit from the hole during deep drilling to clear out accumulated dust.

What to consider before purchase

• Verify the required hole diameter and depth for your specific application
• Ensure your power tool is compatible with the shank type
• Check the material hardness to confirm suitability

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and a dust mask, when drilling into concrete to protect against flying debris and airborne dust particles.
