Distar diamond cutting disc Mastercut 125 mm, model 89568442142 — 125×1.6/1.0×15×22.23

Distar Mastercut diamond cutting disc 125 mm (125×1.6/1.0×15×22.23) is a thin-profile blade engineered for fast, accurate cutting of concrete, masonry, ceramic and similar building materials. Designed for use with angle grinders, this disc supports both wet and dry cutting methods and is intended for construction, renovation and professional trade applications where a narrow kerf and precise cuts are required.

Advantages

The Mastercut disc delivers a combination of speed and cutting precision due to its thin 1.6/1.0 mm profile and diamond-segment technology. Its 125 mm diameter and reduced kerf minimize material loss while improving control and reducing heat buildup during cutting. The design is suitable for use in both wet and dry environments, offering versatility across a range of jobsite conditions.

Suitable for

• Angle grinders with compatible 125 mm discs
• Cutting concrete and reinforced concrete (light tasks)
• Masonry blocks, bricks and stone
• Ceramic tiles and porcelain
• Renovation work requiring narrow kerf and precise cuts

When it may not be suitable

This thin-profile diamond disc is not intended for heavy-duty continuous cutting of large reinforced concrete structures where a segmented or turbo blade designed for high removal rates would be more appropriate. It may also wear faster if used extensively on very abrasive materials without proper cooling or intermittent cutting practices.

Key specifications

• Diameter: 125 mm
• Cutting width (kerf): nominal 1.6/1.0 mm
• Arbor hole options: 15 mm and 22.23 mm
• Suitable cutting methods: wet and dry
• Intended tools: angle grinders

How to use

Fit the disc to an angle grinder ensuring the correct arbor adapter is used so the blade is securely mounted. Check the grinder's maximum permissible RPM and confirm it matches the disc rating before operation. For dry cutting, make straight, steady passes without forcing the blade and allow the disc to cool periodically. For wet cutting, use a controlled water feed to reduce dust and heat. Always follow the angle grinder and disc manufacturer's safety guidance, wear appropriate PPE, and secure the workpiece before cutting.

What to consider before purchase

• Ensure compatibility with your angle grinder arbor size and maximum RPM
• Match the disc type to the primary materials you will cut (concrete, masonry, ceramic)
• Decide between wet or dry cutting needs and site conditions

Usage recommendations

Use the Distar Mastercut 125 mm disc for controlled, precise cuts on tile, brick and concrete where a narrow kerf is beneficial. Prefer intermittent cutting and appropriate cooling for prolonged life; switch to a segmented or turbo blade for high-volume heavy concrete cutting tasks.
