Diamond Core Drill Bit DISTAR T-Concrete SDS+ 82 mm x 65 mm, 4 segments, M16

Diamond core drill bit DISTAR T-Concrete SDS+ 82 mm x 65 mm is a purpose-built core bit for SDS+ rotary hammers. With an overall length of 65 mm and cutting diameter of 82 mm, it features four diamond segments and an M16 threaded connection for attachment to compatible adapters or extension rods. The bit is engineered for cutting through reinforced concrete, masonry and other hard mineral materials, and can be used to make both through and blind holes required for anchors, pipes and cable passages.

Advantages

The four-segment diamond crown delivers balanced cutting performance and improved chip removal compared with continuous-rim designs on similar sizes. A short 65 mm body provides greater control and reduces deflection during drilling in thick or reinforced structures. The SDS+ compatible shank with M16 thread offers secure attachment and quick changes when used with appropriate converters. The concentrated diamond matrix ensures durable wear resistance on abrasive concretes and masonry.

Suitable for

• Drilling through and blind holes in reinforced concrete
• Creating openings for anchors and through bolts
• Forming passages for pipes and electrical conduits
• Core sampling and hole preparation in masonry and hard mineral substrates

Key specifications

• Diameter: 82 mm
• Overall cutting length: 65 mm
• Number of diamond segments: 4
• Shank interface: SDS+ compatible
• Thread connection: M16 (for adapter/extension use)
• Intended materials: reinforced concrete, masonry, hard mineral substrates

How to use

Mount the core bit to a compatible SDS+ rotary hammer using the appropriate M16 adapter or converter if required. Secure the connection and set the tool to rotary or rotary-percussion mode according to material hardness and manufacturer recommendations. Begin drilling with steady moderate pressure, allowing the diamond segments to cut without excessive force. Use intermittent withdrawal to clear dust and slurry; for deeper or through-holes, withdraw periodically to improve cooling and debris removal. Follow the rotary hammer manufacturer’s guidelines for speed, impact settings and cooling when applicable.

Usage recommendations

For best results when drilling reinforced concrete, use water cooling or dust extraction to prolong segment life and reduce airborne dust. Match drilling mode and impact force to the substrate: reduce percussion on delicate masonry. Inspect the bit before use for damage or excessive wear and replace when diamond segments are worn or uneven to maintain hole quality.
