Diamond Core Bit Art-Pol Kronurbis D-82 mm with SDS+ Adapter M16 for Concrete

The Art-Pol Kronurbis diamond core bit D-82 mm with SDS+ adapter and M16 thread is a drilling tool intended for creating neat, circular holes in concrete and similar hard building materials. With an 82 mm cutting diameter and a diamond-segmented crown, this core bit is designed to cut through reinforced and non-reinforced concrete, masonry and comparable substrates when used with rotary hammer drills that accept SDS+ adapters.

Advantages

The diamond cutting segments provide efficient material removal and extended tool life while maintaining a clean bore profile. The integrated SDS+ adapter with M16 thread enables quick and secure mounting to compatible rotary hammers and straightforward replacement of the core bit. Construction of the crown and shank ensures stable performance under the high impact and rotational forces typical of hammer drilling.

Suitable for

• Drilling openings for pipes and conduits in concrete walls and floors
• Creating anchor or sleeve holes for mechanical fastenings
• Installing service penetrations for plumbing, electrical and HVAC systems
• General core drilling tasks on masonry and similar substrates

Key specifications

• Cutting diameter: 82 mm
• Connection type: SDS+ adapter with M16 threaded interface
• Cutting material: diamond-segmented crown
• Intended materials: reinforced and non-reinforced concrete, masonry
• Compatible tool: rotary hammer drills accepting SDS+ adapters

How to use

Secure the core bit to the rotary hammer via the SDS+ adapter and tighten the threaded interface according to the tool manufacturer’s guidance. Mark the drilling position and, if possible, start at low speed to establish the pilot contact. Use steady axial pressure without forcing the bit; allow the diamond segments to cut progressively. For through-holes, withdraw periodically to clear debris and, if applicable, use water cooling only if both the core bit and the tool allow wet drilling. Observe the rotary hammer’s operating instructions, including recommended rotation/impact settings for core drilling.

Usage recommendations

Use appropriate personal protective equipment including eye, ear and respiratory protection. Choose drill speed and feed pressure suitable for the base material, and clear cuttings frequently to avoid overheating. Replace the core bit when cutting efficiency declines or segments become worn.
