Abraboro SDS‑Plus concrete drill bit 12 mm x 450/400 mm, 4‑cutting edges

Abraboro SDS‑Plus concrete drill bit 12 mm x 450/400 mm is a purpose‑built rotary‑hammer bit designed for drilling straight, durable holes in concrete and masonry. The bit features a 12 mm cutting diameter, a total length of 450 mm and a 400 mm effective working length, enabling drilling for through‑holes and anchor fixing in medium‑depth applications. The four‑cutting‑edge head improves cutting efficiency and helps maintain bore straightness when used in SDS‑Plus rotary hammers.

Advantages

The four‑cutting‑edge carbide head provides more contact points for faster material removal and reduced walking at the start of the hole. A hardened shank compatible with SDS‑Plus chucks ensures secure coupling and efficient power transfer from the rotary hammer. The 400 mm working length lets you reach deeper anchor points without frequent repositioning, while the 12 mm diameter suits common anchor and dowel sizes used in construction and installation.

Suitable for

• Drilling through‑holes in concrete and solid masonry
• Preparing holes for anchors, dowels and bolts
• Light demolition tasks where precise, straight holes are required
• Professional and DIY installation of fixtures and supports

Key specifications

• Cutting diameter: 12 mm
• Total length: 450 mm
• Working/usable length: 400 mm
• Head design: four‑cutting‑edge carbide tip
• Shank type: SDS‑Plus
• Recommended material: concrete and masonry

How to use

Fit the Abraboro SDS‑Plus drill bit into the SDS‑Plus chuck of a compatible rotary hammer until it locks. Mark the drilling point and, if necessary, use a center punch to prevent slippage. Start drilling at low speed to establish the hole, then apply steady pressure with hammer‑drill action engaged for concrete and masonry. Periodically withdraw the bit to clear dust and allow cooling, especially when drilling deep holes. After reaching the required depth, retract the bit while the tool is running slowly to help expel residual material.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Select drilling speeds and hammer settings according to your rotary hammer’s manual and the hardness of the material. For anchored fixings, verify required hole diameter and depth for the chosen anchor type before drilling.
