When properly matched to the job and to the saw being used, diamond blades provide fast, economical cuts and a long service life. But using the wrong blade for job conditions, a saw that turns the blade at improper speed, or poor sawing techniques can shorten blade life and hike cutting costs.

Because diamond blades come in a wide variety of sizes and performance levels, selecting the right blade for a job is not an easy task. Blade costs also vary widely, depending on blade quality. Though it may be tempting to buy a lower-cost blade to save money, you can sometimes achieve greater economy--especially on large jobs--by buying a more expensive, high-performance blade that's designed to last longer and cut faster. This reduces labor costs and the cost of the blade per cut.

Many variables affect blade life, including saw speed, characteristics of the material being cut, blade quality, and the skill of the saw operator. Knowing how a diamond blade works and the factors affecting blade life and performance can help you improve cutting productivity and economy.
