Diamond Cutting Disc Distar Meteor H15 400 x 3.5/2.5 x 25.4 mm

Distar Meteor H15 400 x 3.5/2.5 x 25.4 mm diamond cutting disc is engineered for high-performance cutting of concrete, reinforced concrete, masonry and common building materials. The disc features a segmented diamond rim and a two-thickness core design that balances cutting speed with reduced vibration. It is intended for use on angle grinders and abrasive saws with a 25.4 mm arbor and is suitable for professional construction and renovation tasks where durable, fast material removal is required.

Advantages

The segmented diamond rim provides efficient cutting and rapid debris evacuation, reducing the risk of overheating during extended use. The disc’s construction offers a balance between aggressive cutting performance and reliable segment retention, delivering consistent results on hard materials. Its reduced-cut thickness portion supports precise cuts while the thicker core area enhances stability and helps control vibration when used at recommended speeds.

Suitable for

• Cutting concrete and reinforced concrete
• Processing masonry, bricks and blocks
• Work on construction and renovation sites with angle grinders and abrasive saws
• Tasks requiring fast material removal and long disc life

When it may not be suitable

This diamond disc is optimized for hard construction materials and aggressive cutting. It may not be suitable for precision thin cutting of metal, tile porcelain or delicate ceramic finishes, where a finer, continuous-rim blade is preferable. Also avoid using the disc on handheld machines or at speeds above the manufacturer’s recommended limits to prevent unsafe operation and premature wear.

Key specifications

• Diameter: 400 mm
• Segment thickness: 3.5 mm at the rim, reduced to 2.5 mm for the cutting edge
• Arbor diameter: 25.4 mm
• Segmented diamond rim for fast cutting and chip removal
• Designed for use on angle grinders and abrasive saws

How to use

Mount the blade on a tool with a compatible 25.4 mm arbor and ensure the tool is switched off before installation. Verify that the cutting direction marked on the disc matches the tool rotation. Secure the disc according to the tool manufacturer’s instructions and wear appropriate personal protective equipment including eye, ear and respiratory protection. Start cutting with steady pressure; allow the disc to cut at its own speed without forcing it. For reinforced concrete or thick elements, use intermittent cutting and allow cooling periods to avoid overheating.

What to consider before purchase

• Confirm tool compatibility: 25.4 mm arbor and rated RPM within the disc’s safe speed
• Intended materials: optimized for concrete, reinforced concrete and masonry
• Machine type: suitable for angle grinders and abrasive saws, not for dedicated tile saws requiring continuous rim blades

Usage recommendations

Use the disc with appropriate power tools at the correct RPM, maintain a moderate feed rate, and keep the cutting path clear of rebar obstructions where possible. Regularly inspect the disc for damage and replace it if segments become loose or the core is warped. Following safe operating procedures and suitable cooling intervals extends cutting performance and service life.
