Diamond core bit Distar DDS-W 82x65-4x16 for concrete

The Distar DDS-W 82x65-4x16 diamond core bit is engineered for drilling circular holes in reinforced and plain concrete. With an outer diameter of 82 mm and a cutting depth of 65 mm, this segmented diamond crown offers efficient material removal and controlled cutting when used with compatible core drilling machines. The segmented design helps evacuate debris and reduce cutting resistance for steady advancement through concrete substrates.

Advantages

The segmented 4x16 diamond crown provides a balance between cutting speed and segment durability, making it suitable for repetitive drilling tasks. The 82 mm diameter and 65 mm cutting depth deliver consistent hole size and depth control for installations that require precise openings. The construction is optimized for concrete, offering improved wear resistance and stable performance during through-holes and depth-limited drilling.

Suitable for

• Drilling holes for plumbing and water supply penetrations in concrete
• Creating openings for electrical conduits and cable routing
• Anchoring and fastening anchor sockets in concrete structures
• HVAC duct and pipe penetrations through walls and slabs

Key specifications

• Outer diameter: 82 mm
• Cutting depth: 65 mm
• Segment configuration: 4x16 segmented diamond crown
• Intended material: reinforced and plain concrete

How to use

Install the core bit on a compatible core drilling machine following the machine manufacturer's mounting instructions. Secure the workpiece or position the drilling rig to ensure stability and alignment with the required hole location. Begin drilling at moderate feed pressure and maintain consistent cooling and debris removal, using water if the bit and machine support wet drilling. Progress through the concrete while allowing the segmented crown to cut without excessive lateral force. Withdraw the bit periodically to clear cuttings when drilling deep or through heavily reinforced sections.

Recommendations

Use appropriate personal protective equipment, ensure the drilling machine is rated for the bit diameter and cutting depth, and follow safe handling and cooling practices. For extended segment life, avoid excessive feed pressure and keep adequate cooling or flushing during operation.
