## Long description

JOBIextra KORONA diamond core bit, 150 mm diameter with SDS connection (model XT829) is designed for drilling precise circular holes in hard building materials such as reinforced concrete, brick and masonry. The tool is compatible with SDS rotary hammers and SDS-capable drills and is intended for creating clean, accurately sized 150 mm bores for installations where a consistent hole diameter is required.
Advantages
The diamond-segment cutting edge ensures efficient material removal and long tool life when used within the recommended application range. The SDS connection provides secure attachment and fast tool changes in SDS-compatible machines. Robust body construction and optimised cooling gaps reduce sticking and overheating during continuous use, while the 150 mm diameter delivers a standard opening suitable for many plumbing, electrical and ventilation components.

Key specifications
Diameter: 150 mm
Connection type: SDS shank compatible with SDS rotary hammers and drills
Cutting technology: diamond-segment rim for hard materials
Suitable materials: reinforced concrete, brick, masonry
Typical applications: plumbing, electrical, ventilation installations
How to use
Mark the centre of the required 150 mm hole and secure the workpiece or ensure stable positioning against the surface. Fit the core bit into an SDS-compatible rotary hammer or drill and check that the shank locks correctly. Start drilling at low speed to establish the bore, then apply steady pressure and maintain machine rotation appropriate for masonry drilling. Use intermittent operation and withdraw the bit occasionally to remove debris and allow cooling. After completing the hole, remove remaining core and clean the bore edges.
Usage recommendations
Use appropriate personal protective equipment including eye, hearing and respiratory protection. For best results, operate the tool with a machine that provides percussive action suitable for SDS tools, avoid excessive axial force, and keep drilling intervals to prevent overheating. When drilling reinforced concrete, monitor progress and feed rate to reduce wear on the diamond segments.
