Diamond wet drilling head Bosch 42 x 400 mm, G 1/2 thread, model 2608601735

Diamond wet drilling head Bosch 42 x 400 mm with G 1/2 thread is designed for wet core drilling in concrete, masonry and reinforced concrete. The tool features a continuous diamond cutting rim that enables accurate core extraction and smooth wall finish. The G 1/2 connection allows secure water feed for cooling and flushing during drilling, which reduces dust and improves cutting performance when used with compatible core drilling rigs and water-cooled drill systems.

Advantages

The diamond cutting edge delivers consistent drilling speed and long-lasting performance in abrasive materials. Wet operation with the G 1/2 water connection lowers temperature at the cutting zone and removes slurry, which helps prevent premature wear and preserves diamond segments. The 42 mm diameter and 400 mm cutting length provide the reach needed for through-holes and deep core samples while maintaining straightness and minimal breakout.

Suitable for

• Creating precise cores in reinforced concrete and concrete walls
• Cutting openings for pipes, conduits and installations
• Sampling concrete for testing and inspection
• Wet core drilling on masonry and stone surfaces

Key specifications

• Cutting diameter: 42 mm
• Cutting length: 400 mm
• Connection thread: G 1/2 for water feed
• Operation type: Wet drilling with water cooling and flushing
• Cutting edge: Diamond segmented continuous rim for concrete and masonry
• Intended use: Core drilling with rigs and water-cooled systems

How to use

Mount the drilling head on a compatible core drill or rig with the matching connection and ensure the G 1/2 water feed is properly attached. Set up the drilling rig to maintain stable alignment and secure the workpiece or drilling position. Begin drilling at low speed to establish the pilot contact, then increase to the recommended operational speed according to the core drill manufacturer. Maintain a steady feed rate and keep a constant water flow to cool the cutting edge and flush out slurry. Withdraw the core barrel periodically to clear cuttings if required and inspect the diamond rim for wear.

Usage recommendations

Use continuous water supply during operation and follow the core drill manufacturer's specifications for speed and feed. For reinforced concrete, use a controlled feed rate to avoid binding and overheating. Replace the drilling head when diamond segments show significant wear or cutting performance decreases to maintain drilling accuracy and safety.
