Diamond segmented cutting disc KLINGSPOR DT 300U 125 mm (TD125 325346)

The KLINGSPOR DT 300U segmented diamond cutting disc 125 mm is engineered for fast, efficient cutting of masonry materials. Designed with a segmented rim, the disc removes debris effectively and improves cooling during prolonged use. It fits most handheld angle grinders with a 125 mm wheel size and is intended for construction-site tasks where high material removal and cutting speed are needed.

Advantages

The segmented diamond rim provides rapid cutting performance and enhanced debris clearance, reducing clogging when cutting concrete, brick, and similar materials. The construction of the disc supports better cooling, which helps maintain cutting speed and blade life under intensive use. Its diameter and segment design deliver a balance between cutting depth and maneuverability for handheld grinders.

Suitable for

• Cutting concrete and reinforced concrete
• Cutting common masonry materials such as brick and block
• On-site construction and renovation work with handheld angle grinders
• Fast through-cuts where debris evacuation is important

Key specifications

• Disc diameter: 125 mm
• Type: segmented diamond rim for dry or wet cutting where applicable
• Intended use: masonry, concrete, brick and similar building materials
• Compatibility: for handheld angle grinders with a 125 mm wheel size
• Design emphasis: high cutting speed and efficient debris removal

How to use

Mount the disc on a compatible 125 mm handheld angle grinder according to the grinder manufacturer’s instructions and secure it with the correct flange and nut. Use appropriate personal protective equipment, including eye, hearing and respiratory protection, and ensure the workpiece is secured. Allow the blade to reach full speed before engaging the material and use steady, even pressure without forcing the disc. For optimal results on reinforced concrete or dense masonry, make multiple shallow passes rather than attempting a single deep cut.

Usage recommendations

Use the disc primarily for dry cutting on construction sites; if wet cutting is required, confirm compatibility with your grinder and observe manufacturer guidance. Regularly inspect the disc for wear or damage and replace it if segments are cracked or excessively worn. Match cutting speed and feed rate to the material to maximize performance and blade life.
