Diamantboor Kroon Distar T-Concrete 72 x 65-4 voor beton en gewapend beton

Diamond drill bit Distar T-Concrete 72 x 65-4 is designed for core drilling in concrete and reinforced concrete. With a 72 mm outer diameter and a 65 mm working length formed by four diamond segments, the bit provides effective cutting performance and enhanced dust and debris removal during drilling. Intended for use with compatible core drills and drill rigs, this bit is suitable for tasks commonly encountered in construction, renovation and installation work such as creating openings for pipes, conduits and anchors.

Advantages

The segmented diamond crown provides reliable cutting speed and prolonged tool life on both plain concrete and reinforced concrete. Four segments improve chip evacuation and reduce clogging, which helps maintain consistent drilling progress. The bit design balances cooling and wear resistance for stable performance during extended drilling sessions. Manufactured with diamond-impregnated segments, it offers predictable behavior on mixed aggregate and rebar encounters.

Suitable for

• Core drilling holes for plumbing and pipework
• Creating openings for electrical conduits and cable routes
• Installing mechanical anchors and fixing points
• Renovation and retrofit work requiring accurate round holes in concrete

Key specifications

• Outer diameter: 72 mm
• Working length (cutting depth): 65 mm
• Segment configuration: 4 segments for improved chip removal
• Material: diamond-segmented cutting crown suitable for concrete and reinforced concrete
• Intended mounting: for compatible core drilling equipment (verify spindle and arbor compatibility)

How to use

Secure the core drill to a stable drill stand or use a handheld core drilling machine according to the drill manufacturer’s instructions. Ensure correct mounting of the diamond drill bit and verify the connection is tight. Begin drilling at low speed to establish a guide and then increase speed and apply steady, even feed pressure. Use appropriate cooling method recommended for your drill—water cooling is commonly used to extend segment life and reduce dust. If drilling through reinforced zones, proceed steadily to avoid sudden impacts on the bit when encountering rebar. After finishing, retract the bit carefully and clean the segments and arbor before storage.

Recommendations

Use water cooling when possible to minimize heat and extend segment life; select a core drill with suitable power and rotational speed for a 72 mm diameter bit, and always wear appropriate personal protective equipment including eye protection, dust mask or respirator, and hearing protection.
