About This Product
Turbo Diamond Blades for Hard Materials
Alpha® Plus Turbo Diamond Blades are premium cutting blades engineered for fast, efficient cutting of granite, engineered stone, marble, bluestone, and other hard building materials. Alpha also recommends the series for hard cured concrete, making it suitable for stone fabrication, tile installation, masonry, and general construction work.
Continuous Rim for Clean Cutting
The continuous rim diamond blade design combines an uninterrupted cutting edge with a turbo-shaped profile made from premium diamond grit and a durable matrix. This design supports fast material removal while producing clean cuts with minimal chipping in demanding stone and concrete applications.
8mm Diamond Layer for Long Life
An 8mm-tall diamond layer provides extended cutting life during repeated use. The high-performance rim is designed to cut materials ranging from 1-1/4" granite slabs to hard cured concrete while maintaining efficient cutting performance.
4" to 12" Cutting Blade Options
Alpha Plus blades are offered in nine diameters: 4", 4-1/2", 5", 6", 7", 8", 9", 10", and 12". Available configurations fit compatible stone cutters, angle grinders, worm-drive saws, circular saws, and demolition saws. Arbor sizes, blade thicknesses, and maximum RPM ratings vary, so the selected blade must be matched to the power tool.
Wet or Dry Cutting
Alpha Plus is designed primarily as a dry cutting blade, allowing use without a water-feed setup. Alpha also confirms that the blades can be used wet with compatible equipment, which can increase blade life and help control airborne silica dust.
