Drill Bit Set Abraboro SDS-Plus 4-flute for Concrete, diameters 6–12 mm

Abraboro SDS-Plus 4-flute drill bit set for concrete covers common diameters from 6 mm to 12 mm and is designed for use with SDS-Plus rotary hammer drills. These four‑cutting‑edge bits are made for drilling in concrete and masonry, offering improved dust evacuation and stable bit guidance to achieve consistent hole quality when installing anchors, dowels and through‑holes in building materials.

Advantages

The four‑flute geometry reduces clogging and accelerates debris removal during percussion drilling, which helps maintain drilling speed and reduces heat build‑up. SDS‑Plus shank compatibility ensures quick, secure insertion into compatible rotary hammers and reliable torque transfer. The bits are manufactured to provide straight drilling with reduced wandering and a consistent hole diameter across the specified size range.

Suitable for

• Drilling holes for anchors and dowels in concrete and masonry
• Through‑holes for cables and pipes in building structures
• General construction and renovation tasks requiring SDS‑Plus rotary hammer use

Key specifications

• Shank type: SDS‑Plus compatible
• Cutting geometry: 4‑flute (four cutting edges) for improved debris evacuation
• Diameter range: 6 mm, 7 mm, 8 mm, 10 mm, 12 mm
• Material suitability: concrete and common masonry materials
• Intended tool: rotary hammer drills with SDS‑Plus chuck

How to use

Select the bit diameter appropriate for the anchor or through‑hole required and secure the bit in the SDS‑Plus chuck of a rotary hammer according to the tool manufacturer’s instructions. Use the rotary hammer in hammer‑drilling mode for concrete and masonry, applying steady axial pressure without excessive force. Periodically withdraw the bit to clear accumulated dust and allow cooling when drilling deep holes. Follow safety practices such as using eye and ear protection and dust extraction where available.

Usage recommendations

For best results, match drill diameter to fastener specifications, pre‑mark hole positions, start drilling at low speed to establish the pilot position, and use dust extraction or a vacuum when possible to keep the work area clear. Replace bits that show excessive wear or chipping to maintain hole quality and operator safety.
