Diamond Blade Distar 450mm (model 17982445083) for cutting concrete and asphalt

Distar diamond blade 450mm (model 17982445083) is designed for cutting concrete and asphalt with power cutters and saws compatible with 450mm diameter blades. The blade construction focuses on efficient material removal, straight cutting performance and prolonged service life under typical construction and roadwork conditions. It is balanced for stable rotation and intended for use on machines rated for diamond blades of this size.

Advantages

The diamond segment composition and bond are optimized for aggressive cutting of dense materials such as concrete and asphalt while maintaining segment integrity and wear resistance. The 450mm diameter provides a combination of cutting depth and maneuverability for trenching, joint cutting and slab removal. The blade's design reduces cutting time and the need for frequent replacements, helping maintain steady workflow on job sites.

Suitable for

• Cutting reinforced and plain concrete slabs
• Asphalt removal and road resurfacing cuts
• Creation of control joints and expansion joints
• Trench cutting for utilities and drainage
• Use with power cutters and walk-behind saws that accept 450mm blades

Key specifications

• Diameter: 450 mm
• Intended material: concrete and asphalt
• Segment type: diamond segments for hard materials
• Mounting: standard bore compatible with common 450mm saws (verify machine arbor size before use)
• Typical applications: wet and dry cutting depending on machine capability

How to use

Install the blade on a compatible power cutter or walk-behind saw following the machine manufacturer's instructions and ensuring correct flange orientation and torque. Verify that the blade rotates in the indicated direction and that the arbor and flange surfaces are clean and undamaged. Use appropriate feed rates and avoid excessive side pressure to prevent blade damage. If applicable, use water cooling for wet cutting to reduce dust and extend segment life; for dry cutting, follow tool and blade limits for duty cycle and cooling intervals.

Usage recommendations

Always use appropriate personal protective equipment including eye, hearing and respiratory protection. Check machine RPM compatibility with the blade's rated speed, and inspect the blade before each use for damage or uneven wear. Match cutting technique (wet or dry) to site conditions and machine capabilities to achieve optimal blade life and cutting performance.
