Frequently Asked Questions
Everything you need to know about our products, customization options, and ordering process.
What are diamond saw blades used for?
Diamond saw blades are used to cut hard materials such as concrete, stone, asphalt, brick, ceramic tiles, and porcelain. They are widely applied in construction, masonry, and industrial projects, offering high cutting efficiency, durability, and stable performance.
How to tell if a diamond saw blade is dull?
A dull diamond saw blade cuts slower, produces more vibration, and may cause burning or smoking during cutting. The segments often look smooth, shiny, or glazed, and the blade may stop cutting effectively.
Can you put a diamond blade in a circular saw?
Yes, you can use a diamond blade in a circular saw to cut materials such as concrete, tile, and brick, as long as the blade size and arbor match the saw specifications.
Can you put a diamond blade on a chop saw?
Yes, you can use a diamond blade on a chop saw to cut hard materials such as concrete, brick, stone, and tile, as long as the blade matches the machine specifications.
How are diamond blades made?
Diamond blades are made by bonding synthetic diamond grit to a steel core using methods such as hot pressing (sintering), laser welding, or electroplating. The diamond segments are attached to the blade edge to provide efficient cutting of hard materials.
How long do diamond saw blades last?
A diamond tile blade typically lasts 12 to 120+ hours, depending on material hardness and cutting conditions.
