My Buying Guide on ‘1 1 4 Diamond Hole Saw’

I have been using a 1 1/4 inch diamond hole saw for a few years now and I must say, it has been a game changer in my woodworking projects. If you are looking to purchase this tool, here is my buying guide to help you choose the best one for your needs.

1. Understand the Purpose

Before making any purchase, it is important to understand the purpose of the tool. A 1 1/4 inch diamond hole saw is primarily used for drilling holes in hard materials such as porcelain, ceramic, and stone. It is commonly used by plumbers, electricians, and DIY enthusiasts for installing faucets, pipes, and other fixtures.

4. Check the Quality of Diamonds

Since diamonds are the cutting material in these hole saws, it is important to check their quality before making a purchase. Look for high-quality industrial-grade diamonds that are evenly distributed along the rim of the saw for better cutting efficiency.

5. Consider Additional Features

Some 1 1/4 inch diamond hole saws come with additional features such as side holes for water cooling or vacuum attachments for dust collection. These features can make your work easier and improve precision while drilling.

6. Read Reviews

Before finalizing your purchase, make sure to read reviews from other buyers who have used the specific product you are considering. This will give you an idea about its performance, durability, and any other potential issues.
