Structure

  1. Steel Core

    The steel core is the foundation of the blade, providing stability.

  2. Arbor Hole

    The area where the blade connects to the power tool. The arrow around the arbor hole is the cutting direction of the blade.

  3. Drive Pin Hole

    An additional hole on certain diamond blades.

  4. Gullet

    The gullet is the gap between segments. It expels debris and reduces operating heat.

  5. Segment

    Working portion, contains diamonds.

  6. Applications

    The color around the edges of the KLINGSPOR triangle describes the tool's application range.

    • Asphalt: Black
    • Tiles: Green
    • Stone/Fireproof: Blue
    • Concrete: Red
    • Universal: White
  7. Maximum Operating Speed & Maximum RPM

    The left side of the bar shows Maximum RPM (revolutions per minute), while the right side is the maximum operating speed given in meters per second.

  8. Dimensions

    Every diamond cutting blade contains information on dimensions in both units of measurement.

  9. Safety Pictograms

    The pictograms indicate how to use the diamond tools safely. They are located on both the left and right side.

Segments & Gullets

Segments are the teeth at the edge of a diamond blade where the diamonds and bond are held. They are also synthetic (man-made) for ideal shape and quality control. Meanwhile, gullets are the gaps between segments.

Types of Segments

There are various shapes of segments to suit their application. Below are some examples that KLINGSPOR has sold before.

How to Choose the Right Blade

The biggest factor driving the decision for a diamond blade is the material that needs to be cut. Different areas in the United States have different aggregates.

We recently did rescue training with a fire station. Two firefighters did the testing, cutting up the hood of an automobile, each using our blade and the competitor's in turn. We could observe that KLINGSPOR's blade seemed to cut faster and this was confirmed by both testers, adding that our blade seemed to cut more smoothly and required less feed pressure.
