Key FAQs About Diamond Tools: Bond, Selection, Usage & Performance

Professional Guide for Diamond Saw Blades & Core Bits

1. What is a "Bond" (Matrix) in diamond tools?

The metal powder mixture that holdsdiamond crystals in place.

2. What is the "Golden Rule" of selection?

Use Soft Bonds for hard materials(Granite/Cured Concrete) and Hard Bonds for soft, abrasive materials (Asphalt/GreenConcrete).

3. Why use a Soft Bond for hard stone?

So the bond wears away fast enough to exposenew, sharp diamonds to keep cutting.

4. Why use a Hard Bond for abrasive materials?

To prevent the grit from "eroding" thebond too quickly, which would cause diamonds to fall out prematurely.

5.What does Diamond Concentration mean?

The volume of diamond crystals per cubiccentimeter. Higher is not always better; it must match the machine's power.

6. What is Diamond Grit?

The size of the diamond particles. Lower numbers (30#) arecoarse; higher numbers (3000#) are fine.

7. Sintered vs. Laser Welded: What's the difference?

Sintered is for light DIY; LaserWelded is for professional heavy-duty use (highest safety).

8. Can I use a dry blade with water?

Yes, water usually extends the life and reduces dust.

9. Can I use a wet blade dry?

Strictly No. The segments may detach due to overheating,causing injury.

10. What is a "General Purpose" blade?

A compromise tool that works on many materialsbut is master of none.

11. How do I identify the "Hardness" of concrete?

Using a Mohs Hardness Test kit.

12. Does the arrow direction on the blade matter?

Yes, it ensures the diamonds' "comettails" support the cutting edge.

13. What is Arix/Patterned Diamond technology?

Diamonds arranged in precise rows forconsistent, faster cutting.

14. Is a taller segment (15mm vs 10mm) always better?

Not if the bottom 5mm is a "base"with no diamonds. Check the "effective" height.

15. What is Silver Brazing?

A high-frequency welding method common for saw blades and core bits.

16. Why do some blades have copper in the bond?

To help dissipate heat and adjust thewear rate.

17. What is Vacuum Brazing?

A process where diamonds are exposed on the surface,making the tool extremely sharp for "universal" cutting.

18. How does altitude or temperature affect the tool?

Extreme cold can make the steelcore brittle; heat affects the bond's wear rate.

19. What is the shelf life of a diamond tool?

Years, if kept dry. Surface rust doesn't usuallyaffect performance.

20. Is the cheapest tool the most cost-effective?

No. Measure "Cost per Foot/Meter"rather than the purchase price.
