Drill Bit Abraboro SDS-Plus 6.5/210/150 — 4-cut for concrete

Abraboro SDS-Plus 6.5/210/150 — 4-cut for concrete is a carbide-tipped masonry drill bit designed for percussive drilling in SDS-Plus hammer drills. With a 6.5 mm diameter, 210 mm overall length and 150 mm working length, this four-cut geometry bit is optimized for accurate, efficient penetration of reinforced concrete and brick while maintaining stable drilling direction and reduced vibration.

Advantages

The four-cut head geometry provides improved centring and cleaner holes compared with two-flute designs, reducing walking at drill start. Carbide cutting edges increase wear resistance and maintain sharpness during repeated percussive use in concrete and masonry. The SDS-Plus shank enables secure tool engagement and quick bit changes, while the specified working length gives controlled depth for through and blind holes in common construction tasks.

Suitable for

• Drilling holes in reinforced concrete for anchors and dowels
• Creating fixing points in brick and masonry
• Professional trade and construction site applications
• DIY projects requiring precise percussive drilling in hard substrates

Key specifications

• Diameter: 6.5 mm
• Overall length: 210 mm
• Working length: 150 mm
• Shank type: SDS-Plus
• Tip geometry: four-cut (4-cut) carbide head
• Intended materials: reinforced concrete, brick, masonry

How to use

Install the bit into an SDS-Plus hammer drill according to the drill manufacturer's instructions, ensuring it locks securely. Mark the drilling point, start at low speed to establish the hole, then increase speed and apply consistent axial pressure while allowing the percussion action to remove material. Withdraw the bit periodically in deep holes to clear dust and avoid overheating. Use appropriate drill speeds and feed pressure for the substrate and diameter.

Usage recommendations

Use personal protective equipment such as safety goggles, ear protection and a dust mask when drilling concrete. For best performance, ensure the drill's percussion mechanism is enabled and select a compatible anchor or dowel sized for a 6.5 mm hole. Replace the bit when cutting edges show significant wear to maintain hole quality and drilling efficiency.
