Abraboro drill bit set for concrete, Diamant EVO series, 4–10 mm (set)

Abraboro Diamant EVO drill bit set for concrete contains multiple carbide-tipped bits with diameters from 4 mm to 10 mm designed for drilling into concrete and masonry. The set covers a practical range of hole sizes commonly used for anchors, dowels and through-holes and is intended for use with rotary and hammer drilling tools. Abraboro’s Diamant EVO series focuses on durability and consistent cutting performance when penetrating dense mineral materials.

Advantages

The carbide tips provide wear resistance and maintain cutting geometry over repeated use, while the range of diameters in the set reduces the need to switch between separate individual bits. The bits are balanced for steady drilling and constructed to withstand impacts and abrasive stone or aggregate in concrete. This combination delivers predictable hole size and helps reduce breakout or excessive chipping at the hole edge when used with appropriate drilling technique.

Suitable for

• Drilling holes in concrete for anchor bolts and wall plugs
• Preparing mounting points for electrical boxes and plumbing fixtures
• Making through-holes in masonry and cement blocks
• General construction, installation and repair tasks requiring concrete penetration

Key specifications

• Diameter range: 4 mm to 10 mm
• Tip material: carbide-tipped cutting edge
• Intended material: concrete and masonry
• Compatible drilling modes: rotary drilling and hammer drilling
• Typical applications: anchor, dowel and through-hole drilling

How to use

Select the drill bit diameter appropriate for the anchor or dowel being installed. Secure the bit in a compatible drill chuck or SDS adaptor as required by your drilling machine, and set the tool to the recommended mode for concrete (hammer/impact mode when available). Start drilling at low speed to establish the starter point, then apply steady pressure and increase speed as required. Periodically withdraw the bit to clear dust and prevent clogging; when drilling deep holes, withdraw more frequently to remove debris and avoid overheating. Use eye and respiratory protection and follow the drill manufacturer's safety instructions.

Usage recommendations

For best results, match the bit diameter to the fastener manufacturer's recommended hole size, use a hammer drill for dense concrete, and keep the bit clean of dust. Replace the bit when cutting performance decreases noticeably to maintain accurate hole dimensions and reduce the risk of damage to the workpiece.
