Best Diamond Hole Saw

Finding the best diamond hole saw can make or break your next project. This accessory can be complemented with a wide variety of drills when working with hard surfaces.

Of course, not all options on the market offer the best results. For you to acquire high-quality and efficient parts, you will find the best information below. We also discuss the fundamentals of any diamond hole saw. Your best ideas and projects can become reality with some of the following diamond hole saws.

Buying Guide

To obtain the best diamond hole saw we must consider the most important aspects of this accessory. There is a wide variety of similar accessories on the market that do not offer the same results. So, to get the right choice, you should consider the following five aspects.

  1. Part sizes

In general, the different options on the market can be made up of a certain number of pieces. Sometimes options that include a single diamond hole saw offer a universal size.

However, do-it-yourselfers need multiple sizes. Even diamond hole saw sets can include 10 to 12 pieces. This can be much more convenient for accurate results and a higher level of professionalism.

  • Cutting speed

Another important aspect is the cutting speed that each diamond hole saw can offer. Some options can offer a cutting speed of up to 300 revolutions per minute. On more functional parts, a cutting speed of up to 1000 revolutions per minute can be obtained.

The higher the cutting speed, the more efficiently you can work with different hard surfaces. Also, a high cutting speed makes it possible to obtain edges without additional damage. Besides, a wide cutting speed range allows a better adaptation to different surfaces.

  • Surfaces

Not all diamond hole saws can be adapted to all types of surfaces. It is possible to find some pieces that are adapted to only one type of surface such as glass. So, getting the wrong diamond hole saw can mean a bad outcome for your project.

Those options that include multiple pieces within the diamond hole saw set can be adapted to different surfaces. Common surfaces that can be worked with include glass, granite, various marbles, ceramics, porcelain, carbon fiber, among other surfaces. In no case is it possible to work with some metals.

  • Nickel-plated parts

Different diamond hole saws offer different service life and durability. Therefore, the number of holes that can be drilled with each part may vary depending on some of them. Of course, the most important aspect in this regard is the quality of the metal used to manufacture these parts.

Sometimes, a nickel-plated surface can be incorporated to increase the durability of each diamond hole saw. However, not all parts that are available on the market incorporate this treatment during manufacturing. Still, it can be an important feature for professionals who perform several cuts on hard surfaces per day.

  • Accuracy level

The level of accuracy can vary depending on the design in the manufacture of each diamond hole saw. Some options may incorporate a pilot bit. This additional feature gives the user greater precision capability on each cut. Finally, an organizer case for storing the built-in parts is always very useful.
