Diamond Segment Saw Blade MEGA 86580 180 mm, segment height 2.4 mm, slot 7.2 mm

MEGA 86580 diamond segment saw blade is a 180 mm cutting disc with a segmented rim designed for cutting hard construction materials. With a segment height of 2.4 mm and slot width of 7.2 mm, the blade balances cutting durability and chip clearance. It is intended for use on angle grinders and compatible circular saws with matching arbor dimensions and is suitable for cutting concrete, masonry and natural stone where fast material removal and reduced thermal build-up are required.

Advantages

The segmented rim design provides efficient debris evacuation and improved cooling during continuous cutting, which helps maintain blade life and consistent cutting speed. The 2.4 mm segment height offers a compromise between aggressive material removal and segment wear resistance. A 7.2 mm slot allows better chip clearance and reduced clogging when cutting abrasive or wet materials. The blade’s 180 mm diameter makes it compatible with a wide range of handheld grinders and smaller circular cutting machines commonly used on construction sites.

Suitable for

• Cutting reinforced and plain concrete
• Cutting masonry blocks, bricks and pavers
• Cutting natural stone such as limestone and granite (appropriate feed and cooling required)
• Use with angle grinders and circular saws that accept 180 mm blades

When it may not be suitable

This segmented diamond blade is not optimized for precision finishing or very thin, delicate cuts where a continuous rim blade would produce a smoother edge. It may also be less effective on very soft, non-abrasive materials such as wood, plastics or non-reinforced ceramics where other blade types are more appropriate. For high-speed, high-precision tile work or wet fine cutting applications, consider a blade specifically designed for those tasks.

Key specifications

• Blade diameter: 180 mm
• Segment height: 2.4 mm
• Slot (segment gap) width: 7.2 mm
• Rim type: Segmented diamond rim
• Typical applications: Concrete, masonry, natural stone

How to use

Install the blade on a compatible angle grinder or circular saw following the tool manufacturer’s instructions and ensure the arbor and flange fit the 180 mm disc. Securely tighten the blade and verify rotation direction matches the blade marking. When cutting, use steady, even feed pressure—avoid forcing the blade to prevent overheating and premature wear. For dust control and longer life, use wet cutting where compatible with the tool or ensure adequate water suppression and ventilation. Wear appropriate personal protective equipment including eye, ear and respiratory protection.

What to consider before purchase

• Confirm your tool accepts 180 mm blades and matching arbor size
• Match the blade type to the material to be cut (segmented rim for rough, fast cuts in concrete and masonry)
• Check whether wet or dry cutting is required for your application and tool compatibility

Usage recommendations

For best results on concrete and masonry, use controlled feed rates, allow the blade to cool between long cuts, and maintain dust suppression. Replace the blade when cutting performance decreases or when segments show significant wear.
