All diamond tool products including blades, coring bits, hole saws and grinding wheels include a limited lifetime warranty against warping, cracking and material defects. If any diamond tool (being used for its intended purpose with at least 50% of the diamond life remaining) fails to cut or work properly, or if the bond between the diamond segment and the steel core becomes separated at any time, the tool may be replaced free of charge.

FAQs About Saw Blade RPMs

Why is it important to follow the recommended RPM?

Following the recommended saw blade RPM ensures the blade operates at optimal cutting speed, minimizes wear, and reduces the risk of damage to the blade or equipment.

What happens if I exceed the maximum RPM for a diamond blade?

Exceeding the maximum RPM can cause the blade to overheat, warp, or even break, potentially leading to unsafe working conditions.

What does SFPM mean in the chart footnote?

SFPM stands for Surface Feet Per Minute. It measures the speed at which the blade’s edge moves through the material being cut. The chart is based on a standard of 9,500 SFPM for optimal performance.

How do I determine the correct RPM for my saw and blade?

Match the blade diameter with the corresponding RPM values in the chart. Use the recommended RPM as a guide for safe and efficient cutting.

Can I use a blade at a lower RPM than recommended?

Using a blade at a significantly lower RPM than recommended can reduce cutting efficiency and may result in uneven cuts or slower performance.

Use the table below for cutting depth guidelines - actual depths may vary slightly.

12-Inch	4"
14-Inch	5"
16-Inch	6"
