Diamond Blade Distar 300 mm for Concrete and Asphalt, model 14320347025

Diamond blade Distar 300 mm for Concrete and Asphalt, model 14320347025 is a circular cutting disc designed for use on angle grinders and walk-behind saws that accept 300 mm blades. The blade is intended for cutting reinforced and plain concrete as well as asphalt surfaces, delivering stable performance when working on construction, road repair and renovation projects. Its construction is optimized for effective material removal, long life, and consistent cutting speed under typical jobsite conditions.

Advantages

The Distar 300 mm diamond blade combines a durable segmented rim with a reinforced steel core to resist bending and vibration during heavy-duty cutting. Segmented rim geometry allows faster cutting and efficient debris evacuation, reducing friction and overheating. The blade is balanced for stable rotation on both handheld angle grinders and dedicated walk-behind saws, providing uniform kerf width and predictable results. Materials and manufacturing methods focus on consistent diamond distribution and bond strength to extend service life when used on concrete and asphalt.

Suitable for

• Cutting reinforced and plain concrete slabs and panels
• Trenching and removing asphalt layers on roads and pavements
• Making control joints and expansion cuts in slabs
• Preparation tasks in renovation and demolition work
• Use with compatible 300 mm angle grinders and walk-behind saws

Key specifications

• Diameter: 300 mm
• Intended materials: concrete and asphalt
• Design: segmented rim with reinforced steel core
• Usage on: angle grinders and walk-behind saws accepting 300 mm blades
• Typical applications: construction, road work, renovation

How to use

Mount the blade on a compatible tool following the machine manufacturer's mounting and safety instructions. Ensure the blade rotation direction marker matches the tool's rotation. Verify that the blade is compatible with the machine's maximum RPM and securely tighten the arbor nut. Start cutting with steady, controlled feed speed appropriate to the material; avoid forcing the blade to prevent overheating or excessive wear. Allow the blade to cool periodically during prolonged cutting and use water cooling if the blade and machine specification allow it for reduced dust and extended blade life.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection, gloves and respiratory protection. Inspect the blade for damage before each use and do not use if the blade shows cracks, missing segments, or severe warping. Match cutting method and feed rate to the material hardness and reinforcement to achieve efficient cutting and longer blade life.
