Core Drill Bit for Concrete MEGA 65 mm, M22 Thread (model 82965)

Diamond-tipped core drill bit for concrete MEGA 65 mm with M22 threaded connection is designed to cut precise circular holes in concrete, reinforced concrete and masonry. This 65 mm diameter bit is suitable for use with core drilling machines and rotary hammer adaptors that accept an M22 mounting, enabling clean openings for mechanical and electrical installations. The tool is intended for through-holes or partial-depth coring where a uniform bore and minimal chipping are required.

Advantages

The diamond segment tip provides fast penetration and long life when drilling abrasive materials such as concrete and masonry. The robust steel body ensures straightness and stability during operation, reducing wobble and improving accuracy. The M22 threaded connection offers wide compatibility with standard core drill adapters and many rotary hammers, allowing straightforward attachment and quick bit changes. The 65 mm cutting diameter covers common needs for conduit, pipe and anchor installations while producing a neat, circular hole.

Suitable for

• Creating holes for plumbing pipes and HVAC duct penetrations
• Routing conduits and cable entries through concrete walls and floors
• Installing anchors, sleeves and through-fixings in masonry
• Contractor and service work requiring repeatable, clean cores

Key specifications

• Cutting diameter: 65 mm
• Tip type: diamond segments for concrete and masonry
• Shank/thread type: M22 threaded connection
• Body material: hardened steel
• Typical applications: wet or dry coring when used with appropriate equipment

How to use

Mount the core bit onto a compatible M22 adaptor or directly to a drill with M22 fitting according to the machine manufacturer’s instructions. Secure the workpiece or position the drill rig to ensure stability and correct alignment with the intended hole. Begin drilling at low speed to establish the pilot contact, then increase speed and apply steady, even pressure; avoid excessive side loads. Use water cooling where recommended by the drill machine and bit manufacturer to extend diamond life and reduce dust if wet coring is suitable. Withdraw the bit periodically to clear debris when dry coring and let the tool cool between long runs.

Usage recommendations

Use appropriate personal protective equipment including eye, ear and respiratory protection. Match the drill bit to a machine with sufficient power and correct mounting for M22 connection. For reinforced concrete, proceed with controlled feed and consider pilot drilling or segmented cutting to reduce stress on the bit. Follow the core drill and diamond bit manufacturer’s guidance for wet versus dry operation and cooling to maximise performance and service life.
