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.

Bringing a 1976 MG Midget to the modern world!
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
I've been restoring a 1976 MG Midget barn find. I bought some Sinless liner to help make the car rattle less and feel more solid. This product is easy to cut, easy to install, and extremely sticky. I used it to line the trunk, the interior, and even some under the hood of the old MG. The adhesive stands up to the brutal temperature of the engine bay, and when (by accident) some fuel spilled onto the foam, it didn't fall apart or turn to mush. Thanks to Siless, the MG now feels like a modern car. The floor pans feel much more solid, the doors make a heftier thud when you close them, and the trunk no longer sounds like a percussion instrument when you touch it. If you know what you're doing, this product will transform the feel of a car. I found that 36 sq ft was enough for my MG Midget, but for a bigger car I would want more. The pattern on the back helped me to cut perfectly measured squares and rectangles. The foam itself doesn't have a strong odor, it works super well, and has held up to several months of changing temperatures (in the Midwest US.)
