The Dart Red Ten DCD Spiro 38mm diamond core bit is a professional-grade tool designed for tradespeople and contractors who require clean, fast, and precise drilling in masonry, brick, concrete, and natural stone. Its standout benefit is the integrated spiral barrel design, which significantly enhances dust removal and thermal management during operation. While this bit delivers exceptional durability and efficiency in diverse materials, it is specifically optimized for dry drilling, meaning it should not be forced into high-impact wet-drilling applications or used on heavy-gauge steel rebar.

No, this is a dry diamond core bit. Using it with water may damage the bonding agent in the segments.
Yes, but you must disable the percussion or 'hammer' action, as impact mode will damage the diamond segments.
The wall thickness is 2.0mm, providing a balance between durability and cutting speed.
It is suitable for concrete with light or medium steel reinforcement, but it is not intended for heavy-duty structural steel.
Avoid overheating by letting the bit clear dust periodically, use the correct rotation speed, and apply steady, consistent pressure.
It uses a standard 1/2 inch BSP female threaded shaft.
The diamond segments have become polished. Drill into an abrasive material like a soft brick or a dressing stone to expose fresh diamonds.
Ensure the adaptor is tightened securely and verify that the drill is centered. Check the core bit for any signs of mechanical distortion.
The spiral barrel may be clogged. Stop drilling, remove the bit, and clear any impacted debris from the side vents and barrel.
To set up the bit, ensure your drill or rotary hammer is set to a rotary-only or low-impact setting to prevent structural damage to the segments. The bit utilizes a standard 1/2 inch BSP female thread; ensure your core adaptor is cleaned and free of debris before threading.
Compatibility: This bit is compatible with most standard core drill adaptors and can be used on masonry drills or rotary hammers in non-percussion mode.
