Diamond segmented blade Tvardy 350x12x25.4/20 mm with ring — pack of 10

Diamond segmented blade Tvardy 350x12x25.4/20 mm with ring — pack of 10 is a set of ten diamond cutting discs designed for high-speed cutting of concrete, masonry and similar construction materials. The blade features a segmented rim that enhances cooling and clears debris during cutting. A supplied center ring allows adaptation to machines with a 20 mm bore while maintaining compatibility with 25.4 mm spindles when the ring is removed. The set is intended for use with angle grinders and cut-off saws that accept 350 mm diameter blades and the stated bore sizes.

Advantages

The segmented diamond rim provides efficient chip clearance and improved cooling, reducing the risk of overheating during continuous cutting. A consistent diamond bond offers reliable cutting performance on hard materials such as concrete and brick. Packaging as a pack of 10 ensures availability of spare blades on site and reduces downtime for professional users. The inclusion of a center ring increases machine compatibility without altering blade performance.

Suitable for

• High-speed cutting of reinforced and unreinforced concrete
• Masonry and brick cutting on construction sites
• Cutting paving stones, curbstones and similar hard stone materials
• Use with compatible angle grinders and cut-off saws in professional settings

Key specifications

• Diameter: 350 mm
• Blade thickness: 12 mm
• Bore options: 25.4 mm and adapter ring to 20 mm
• Segmented diamond rim for improved cooling and debris removal
• Pack quantity: 10 blades

How to use

Fit the blade to an angle grinder or cut-off saw with the appropriate spindle diameter; install the supplied center ring if your machine requires a 20 mm bore. Ensure the blade is mounted in the correct rotation direction and securely tightened according to the machine manufacturer's instructions. Use steady feed pressure and allow the diamond segments to perform the cutting; avoid forcing the blade to prevent overheating and premature wear. Wear appropriate personal protective equipment such as eye protection, hearing protection and dust mask when cutting.

Usage recommendations

For longer blade life and consistent cut quality, use water cooling only if the machine and blade specification allow wet cutting; otherwise perform dry cutting in short, controlled passes to minimize heat build-up. Inspect blades regularly for segment wear or damage and replace any blade that shows cracking or significant segment loss.
