Riving knifes

(16 Products)

Riving knives are crucial safety components for table and panel saws, designed to prevent kickback by keeping the cut pieces of wood from pinching the blade. These steel knives adhere to DIN specification 38820 and can be adjusted correctly in Suva and DIN riving knife holders. Selecting the appropriate riving knife thickness is vital to ensure safety and optimal performance.

Key Features: -

DIN Specification 38820 Compliance: All riving knives in this category meet the rigorous DIN 38820 standards, ensuring high quality and reliability. 

Compatibility: These knives are adjustable in both Suva and DIN riving knife holders, providing flexibility for different machine setups.

Range of Sizes: Available for saw blade diameters ranging from 250mm to 800mm, covering a wide spectrum of industrial and commercial applications.

Determining the Thickness of a Riving Knife - Selecting the correct riving knife thickness involves understanding the relationship between the thickness of the knife (e), the width of the cut (B), and the saw blade center thickness (b).

The basic principle to follow is: The riving knife thickness (e) must be less than the width of the cut (B) but at least as thick as the saw blade center (b).

Rule of Thumb To simplify the selection process, use the following formula: e = B + b / 2 Choosing the Right Thickness For Saw Blades with Set Teeth: If the calculated thickness is not available, opt for the next smaller thickness.

For Tungsten-Carbide-Tipped Saw Blades: If the calculated thickness is not available, choose the next larger thickness.

Practical Example For a saw blade with a diameter between 250mm and 800mm:

Step 1: Measure the width of the cut (B).

Step 2: Measure the saw blade center thickness (b).

Step 3: Apply the formula: e = B + b / 2.

Step 4: Select the appropriate riving knife based on whether your blade has set teeth or is tungsten-carbide-tipped, adjusting to the nearest available thickness as necessary.

By following these guidelines, you can ensure the correct and safe operation of your table and panel saws, enhancing both performance and safety in your woodworking projects.
