Hammer drill bit set Bosch Expert SDS plus-7X, Ø 6 mm, 30 pcs

Bosch EXPERT SDS plus-7X hammer drill bit set, 30 pieces of 6 mm diameter bits, designed for SDS-plus rotary hammer drills. The set is intended for repeated hammer-drilling tasks in concrete and masonry where a 6 mm hole is required. The bits feature a full-carbide 4-cutter head engineered to resist jamming on rebar and to extend tool life during heavy use.

Advantages

The full-carbide 4-cutter head provides improved impact resistance and reduces the likelihood of bits sticking or breaking when encountering reinforcement. Carbide tip technology increases durability and maintains cutting performance over many holes. Compatible with all SDS-plus rotary hammer drills, the set offers consistent hole quality and reliability for frequent drilling in concrete and stone.

Suitable for

• Drilling 6 mm holes in concrete
• Fixings and installations in masonry
• Repeated hammer-drilling tasks on reinforced concrete and stone
• Use with SDS-plus rotary hammer drills

When it may not be suitable

This 6 mm bit set is not suitable for drilling larger diameter holes or for applications requiring masonry bits without hammer action. For delicate materials such as ceramic tiles or glass, a dedicated bit type should be used to avoid chipping or cracking.

Key specifications

• Quantity: 30 pieces
• Shank type: SDS-plus
• Drill diameter: 6 mm
• Overall length: 165 mm (working length approx. 100 mm)
• Head type: Full-carbide 4-cutter

How to use

Install an SDS-plus bit into the rotary hammer according to the drill’s instructions until it locks. Select hammer mode and set appropriate drilling speed and pressure for 6 mm holes in concrete. Start drilling with steady forward pressure; withdraw periodically to clear dust for efficient cutting and longer bit life. Replace bits when tip wear significantly reduces drilling performance.

What to consider before purchase

• Ensure compatibility with your tool’s SDS-plus chuck
• Confirm that 6 mm diameter and the working length meet your application requirements
• Choose full-carbide 4-cutter design for reinforced concrete tasks

Usage recommendations

For best results when drilling reinforced concrete, use the bits in hammer mode with controlled pressure, clear debris often, and match bit length to the depth of the fixing. Replace worn bits to maintain hole quality and reduce stress on the rotary hammer.
