Diamond core drill bit Distar 110 mm diameter, 10 mm segment height

Diamond core drill bit Distar 110 mm diameter, 10 mm segment height is engineered for controlled and accurate hole drilling in construction materials such as concrete, reinforced concrete, brick and masonry. The tool integrates a 110 mm cutting diameter with 10 mm-high diamond segments to balance cutting efficiency and segment durability. It is suitable for use with core drilling machines and compatible hand-held drill rigs when the correct adapter and mounting interface are used. Proper speed, coolant and feed control help achieve consistent hole quality and extend segment life.

Advantages

The 110 mm diameter and 10 mm segment height provide stable cutting performance while delivering predictable wear characteristics. High-quality diamond abrasive in the segments ensures effective penetration of dense materials and consistent removal of debris when used with adequate water cooling. The bit is designed to maintain circular hole tolerance and minimize chipping on brittle substrates. Compatibility with common core drilling systems enables straightforward replacement and mounting.

Suitable for

• Drilling holes for plumbing and electrical installations in concrete and masonry
• Creating anchor and dowel holes in reinforced concrete
• Opening passages for ventilation or piping through brick walls
• Installation and retrofit works requiring precise circular openings

Key specifications

• Cutting diameter: 110 mm
• Segment height: 10 mm
• Intended materials: concrete, reinforced concrete, brick, masonry
• Cooling method: water-cooled operation recommended
• Typical mounting: standard core drill interface for machine and hand-held rigs

How to use

Mount the core bit onto a compatible core drilling machine or an adapter for a hand-held drill, ensuring secure fastening and correct concentric alignment. Position the drill perpendicular to the work surface and start at low speed to establish the pilot engagement, then increase to the recommended operating speed for the material being drilled. Use continuous water cooling to suppress dust, lubricate the diamond segments and remove slurry from the cutting area. Apply steady, even feed pressure—avoid excessive force—to let the diamond segments cut efficiently. Periodically withdraw the bit to clear debris and allow cooling, especially when drilling deep holes.

Usage recommendations

For best results, use water cooling and a drill with stable torque. Match rotational speed and feed rate to the material hardness: lower speeds for hard, reinforced concrete and higher speeds for softer masonry. Inspect the segments regularly for uneven wear and replace the bit when cutting efficiency declines. Avoid dry drilling and excessive side loads to prevent premature segment damage.
