Core Drill Bit Abraboro 122/450 mm S10 — Abraboro

Abraboro core drill bit 122/450 mm S10 is a cylindrical core cutter engineered to remove concrete and masonry cores with a 122 mm cutting diameter and a total length of 450 mm. Designed for use in rotary and core drilling systems that accept S10-style shanks or holders, this drill bit is intended for creating precise through-holes and service openings in building materials. The tool is oriented toward professional tradespeople and installers who require repeatable, clean core extraction in renovation and installation tasks.

Advantages

The Abraboro core drill bit provides a consistent 122 mm diameter cut and a 450 mm overall reach, enabling access through thicker walls or slabs without changing tools. Its cylindrical geometry supports clean core removal and reduces chiselling after drilling. Compatibility with common S10 holders simplifies mounting in standard core drilling rigs or handheld core drills. The design balances rigidity and cutting performance for predictable results on concrete and masonry.

Suitable for

• Creating through-holes for pipes and cables in concrete and masonry
• Installing service openings and inspection ports in walls and floors
• Work by electricians, plumbers, HVAC installers, and general construction contractors
• Renovation tasks requiring repeatable core diameters and clean edges

When it may not be suitable

This core drill bit is intended for concrete and masonry; it is not designed for cutting metal, wood, or softer non‑masonry materials. It requires an appropriate S10-compatible holder or core drilling rig and sufficient drilling power — using underpowered equipment may result in slow progress or overheating. For very shallow holes or small-diameter drilling, a smaller diameter bit or different drill type may be more efficient.

Key specifications

• Cutting diameter: 122 mm
• Total length: 450 mm
• Design: cylindrical core cutter
• Intended materials: concrete and masonry
• Shank/connection type: compatible with S10-style holders

How to use

Mount the Abraboro 122/450 mm core drill bit into an S10-compatible holder or core drilling rig according to the holder manufacturer’s instructions. Securely fix the drilling rig or drill to prevent movement and ensure perpendicular entry to the work surface. Use appropriate drilling speed, steady feed pressure, and water cooling or dust extraction where applicable to control heat and material removal. Withdraw the bit periodically to clear debris and remove the core once the cut is complete. Follow the safety and operating guidelines of your drilling equipment and wear personal protective equipment.

What to consider before purchase

• Ensure your drilling rig or holder is compatible with S10-style connections
• Verify that a 122 mm cutting diameter and 450 mm length meet the required hole size and depth
• Confirm the bit is intended for the specific masonry or concrete type you will work on
• Check that your drill or rig provides sufficient power and that cooling or dust control can be applied

Usage recommendations

Operate the bit at recommended drilling speeds for masonry, use water cooling where possible to extend tool life, and support the drilling rig to maintain alignment. Regularly clear debris and inspect the bit for wear; replace if cutting performance or core quality declines.
