Product information

Description

Extension piece for diamond crowns 50 cm 1 1/4" Dedra HW4005 is a rigid extension rod designed to increase the working reach of diamond cutting and drilling crowns. The 50 cm length provides additional access for deep or hard-to-reach masonry and concrete drilling tasks, allowing users to maintain tool alignment and stability when connecting core bits to rotary or core drilling equipment.

Advantages

The extension piece offers a solid, vibration-minimizing connection that helps preserve cutting precision at extended depths. Its threaded 1 1/4" connection ensures compatibility with a range of diamond crowns and drilling machines using the same thread standard. Constructed for use with masonry and concrete, the extension maintains stiffness under load to reduce deviation and facilitate straighter holes and cuts.

Suitable for

  • Extending reach for diamond cutting crowns during deep concrete or masonry cutting
  • Core drilling where additional length is required to access recessed areas
  • Renovation and construction tasks that demand precise alignment at depth
  • Connecting to rotary and core drilling equipment that accept a 1 1/4" threaded interface

Key specifications

  • Length: 50 cm
  • Thread connection: 1 1/4" (female/male as required for system compatibility)
  • Intended material use: masonry and concrete
  • Function: rigid extension for diamond cutting and core drilling crowns

How to use

Attach the extension piece between the diamond crown and the drilling machine using the 1 1/4" threaded connection, ensuring threads are clean and undamaged before assembly. Tighten securely according to manufacturer torque recommendations for the drilling equipment to maintain alignment. Operate the drill at appropriate speed and feed rate for the crown and material; monitor for vibration or misalignment and stop to re-tighten or inspect connections if necessary.

Usage recommendations

Use the extension piece only with compatible diamond crowns and drilling equipment that accept a 1 1/4" connection. Inspect threads and the extension rod for wear or damage before each use. For safer and more accurate results in deep drilling, support the drill and use steady feed pressure; avoid excessive lateral forces that can bend the extension or damage the crown.
