Bosch Expert SDS Max-8X Hammer Drill Bit 14 mm Diameter 340 mm Length for Concrete and Reinforced Concrete

The Bosch Expert SDS Max-8X hammer drill bit with a 14 mm diameter and 340 mm length is engineered for rotary hammers to tackle demanding drilling tasks in tough materials such as concrete, stone, masonry, and reinforced concrete. Designed for professional construction and renovation projects, this accessory provides high durability, structural reliability, and consistent precision when handling heavy-duty applications.

Advantages

This hammer drill bit features an advanced 4-cutter head made entirely from solid metal using Bosch Carbide Technology, which prevents jamming and ensures high resistance to impact stress. The single-piece full carbide design distributes force evenly, reducing wear and tear during intensive tasks such as penetrating rebar or drilling deep anchor holes in reinforced concrete. It helps minimize accessory replacement frequency and maintains stable performance throughout extended working periods.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Masonry and stone renovation work
• Professional construction projects
• Installing heavy-duty anchors and rebar extensions

When it may not be suitable

This tool is not recommended for drilling in soft materials such as wood, drywall, or plastics, where standard twist or multi-purpose drill bits are more appropriate. It is also not compatible with standard rotary drills that lack an SDS max chuck system.

Key specifications

• Tool holder type: SDS max
• Drill bit type: Hammer drill bit
• Diameter: 14 mm
• Total length: 340 mm
• Head design: 4-cutter full carbide head
• Compatible materials: Concrete, reinforced concrete, masonry, stone

How to use

Insert the hammer drill bit firmly into the SDS max chuck of a compatible rotary hammer until it securely locks into place. Position the tip perpendicularly against the target surface before starting the tool. Apply steady, moderate pressure without forcing the drill, allowing the hammer action and carbide head to break through the material efficiently. Periodically withdraw the bit from the hole during deep drilling to clear out accumulated dust and debris.

What to consider before purchase

• Verify that your rotary hammer drill supports the SDS max connection system
• Ensure the 14 mm diameter and 340 mm length match your specific depth and hole size requirements
• Confirm that your primary application involves hard mineral substrates like concrete or reinforced concrete

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses, hearing protection, and a dust mask, when operating rotary hammer drills. Keep the drilling area well-ventilated and allow the bit to cool down periodically during continuous heavy-duty use to maximize its operational lifespan.
