Description

Achieve Professional Speed and Precision with Delux-Cut Turbo Rim Technology

The Diamond Products 21124 4-Inch Delux-Cut Circular Blade is a high-performance solution engineered for aggressive cutting in demanding materials. Featuring a specialized Turbo Rim design, this blade minimizes surface-to-surface contact to deliver significantly faster cutting speeds than standard segmented blades. It is the perfect choice for contractors and DIYers working with general-purpose concrete, asphalt, and masonry block, providing a smooth finish without sacrificing material removal rates.

Built for versatility and longevity, this diamond blade features a 0.500-inch segment height and a deep 0.400-inch diamond concentration to ensure an extended service life even in heavy-duty applications. Designed to withstand the rigors of high-speed operation, the 21124 is compatible with both electric circular saws and side grinders. Whether you are performing precise dry cuts or utilizing water for dust suppression in wet applications, this Delux-Cut series blade delivers the reliability and clean performance required for professional-grade results.

Key Features

  • Turbo Rim Design: Serrated segments reduce friction for faster, cooler cutting through hardened materials.
  • Extended Diamond Depth: Features a 0.400-inch diamond depth for long-lasting cutting performance.
  • Tall Segment Height: A 0.500-inch (13mm) segment height provides more wearable material for a better ROI.
  • Wet or Dry Versatility: Engineered to perform at peak levels in both dry and wet cutting environments.
  • Universal Compatibility: Optimized for use with standard electric circular saws and angle grinders/side grinders.

Pro-Tip: To prevent the diamond segments from glazing over when cutting concrete, avoid applying excessive downward pressure. Let the weight of the saw and the high RPM of the turbo rim do the work; if the cutting speed slows down, briefly cut through an abrasive material like a soft brick to "re-dress" the blade and expose fresh diamonds.
