Drill Bit Set Abraboro SDS-Plus THOR 2-Cutter for concrete, sizes Ø5–Ø12

The Abraboro THOR SDS-Plus 2-Cutter drill bit set for concrete includes a range of solid masonry bits in diameters Ø5, Ø6, Ø6.5, Ø7, Ø8, Ø9, Ø10, Ø11 and Ø12. Designed for use with rotary hammers that accept SDS-Plus chucks, these two-flute bits are intended for efficient drilling into concrete and common masonry materials. The set is suitable for professionals and skilled DIY users who need compact, robust bits for drilling anchor holes, through-holes and fixture mounting in construction and renovation settings.

Advantages

These Abraboro THOR bits feature a two-cutter (2-flute) head geometry that provides stable centring, controlled chip removal and consistent hole quality in reinforced and non-reinforced concrete. The SDS-Plus shank enables quick, secure tool engagement and fast bit changes. The set covers a practical diameter range from 5 to 12 mm, reducing the need to purchase individual sizes and ensuring compatibility with common anchor and fixing diameters used in building and installation work.

Suitable for

• Drilling anchor and fixing holes in concrete, brick and blockwork
• Installing electrical boxes, conduit and plumbing fixings
• General construction and renovation drilling tasks
• Professional contractors and experienced DIY users requiring SDS-Plus bits

Key specifications

• Bit type: two-cutter (2-flute) solid masonry drill bits
• Shank type: SDS-Plus compatible
• Material compatibility: concrete, brick, blockwork and similar masonry
• Diameter range: Ø5 mm to Ø12 mm (incremental sizes included)
• Intended tool: rotary hammer / hammer drill with SDS-Plus chuck

How to use

Select the drill bit with the correct diameter for the intended fixing or anchor. Insert the SDS-Plus shank fully into the rotary hammer chuck until it locks. Use the hammer drilling mode when penetrating concrete; apply steady axial pressure without excessive force and allow the tool to do the work. Periodically withdraw the bit to clear dust and debris, especially when drilling deeper holes, to maintain drilling efficiency and reduce heat build-up.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. For reinforced concrete, use controlled feed pressure and consider pre-drilling or using a bit specifically rated for heavy reinforcement where appropriate. Store the bits in a dry place and avoid sideways impact to preserve cutting edges and shank integrity.
