## Long description

JOBIextra KORONA SDS 100 mm is a diamond core drill bit designed for use with SDS-compatible rotary hammer tools. The XT827 model has a 100 mm cutting diameter and a segmented diamond crown that enables fast penetration and controlled coring in concrete, reinforced concrete, masonry and similar mineral substrates. The tool is intended for creating precise circular openings for installations where clean, repeatable holes are required.
Advantages
The diamond-segmented crown provides effective material removal and extended cutting life compared with abrasive bits. The SDS connection ensures secure fitting and efficient transfer of impact and rotation from the rotary hammer. The 100 mm diameter is suitable for many installation tasks while the cylindrical body facilitates easy extraction of the core. The construction of the bit supports steady drilling performance and reduced risk of jamming during coring.
Suitable for
 Core drilling openings for plumbing and pipe installation in concrete and masonry
 Electrical conduit and junction box recesses in walls and floors
 Creating anchor and inspection holes in reinforced concrete
 General construction and renovation tasks requiring circular holes up to 100 mm
Key specifications
 Cutting diameter: 100 mm
 Connection type: SDS-compatible shank
 Cutting material: diamond-segmented crown
 Intended substrates: concrete, reinforced concrete, masonry and similar mineral materials
 Design: cylindrical core barrel for easy core removal
How to use
Mount the JOBIextra KORONA SDS core bit securely into an SDS-compatible rotary hammer according to the tool manufacturer's instructions. Mark the drilling location and, when possible, start with a pilot point or guide to position the bit. Use appropriate speed and moderate pressure; allow the bit to do the cutting rather than forcing it. For reinforced concrete, maintain steady feed and retract periodically to clear dust and cool the segments. When the hole is complete, stop the tool before extracting the core to avoid damage to the bit or the work surface.
Usage recommendations
Use personal protective equipment including eye protection, hearing protection, and a dust mask or extraction when drilling. For prolonged life and optimal performance, use water cooling or periodic wetting when permitted by the rotary hammer and job conditions; otherwise, clear dust frequently. Select drilling speeds and impact settings according to the rotary hammer manufacturer's guidance and the hardness of the material being drilled.
