Core Drill Bit for Concrete MEGA 80 mm with M22 Thread, Model 82980

The MEGA core drill bit for concrete, 80 mm diameter with M22 threaded connection, is designed to produce accurate circular holes in concrete and comparable masonry materials. Compatible with rotary and diamond core drilling tools that accept M22 fittings, this bit is intended for creating precise 80 mm openings required in plumbing, electrical conduit, and HVAC installations. The construction balances cutting performance and durability for repeated use on reinforced and non-reinforced concrete.

Advantages

This 80 mm core drill bit delivers clean, consistent hole edges and reliable centring thanks to its M22 threaded interface for secure attachment to compatible drills. The bit’s design supports efficient chip removal and controlled cutting speed, reducing drilling time while maintaining hole accuracy. Built from materials suited to masonry work, it offers wear resistance and retains cutting performance across multiple holes under normal professional use.

Suitable for

• Drilling 80 mm circular openings in concrete walls and floors
• Creating passages for plumbing pipes and water lines
• Installing electrical conduits and cable runs
• Forming openings for HVAC ducts and ventilation components
• Retrofit and construction site penetrations in masonry structures

Key specifications

• Diameter: 80 mm
• Thread type: M22 connection for rotary/diamond core drilling tools
• Intended material: Concrete and similar masonry
• Hole shape: Circular
• Typical applications: Plumbing, electrical, HVAC installations

How to use

Select a compatible drilling machine that accepts an M22 threaded core bit and ensure the machine’s power and speed settings match the material and bit size. Mark the drilling location and, if possible, use a pilot mark to improve centring. Secure the workpiece or confirm the stability of the structure. Attach the core bit to the drill using the M22 thread and tighten according to the drill manufacturer’s instructions. Start drilling at a low speed to establish the hole, then increase speed and apply steady, even pressure; use water cooling if the drill setup and jobsite conditions permit to reduce heat and prolong bit life. Withdraw the bit periodically to clear debris and inspect progress until the full 80 mm depth or required penetration is achieved.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and dust control measures. Match drill speed and feed to the concrete type and reinforcement; when drilling reinforced concrete, use steady pressure and frequent cooling or flushing to prevent overheating. For best results, pair the bit with a drill rated for core drilling and follow the tool manufacturer's guidance on torque and rotational speed.
