3.5 Inch Diamond Hole Saw — Masonry Drilling

Turbo Rim diamond hole saws are designed for faster material removal and are available in smaller sizes up to 2 inches. Straight Rim versions, used in sizes from 2.25 inches and above, produce cleaner, smoother cuts with less chipping, making them ideal for precision tile and stone applications.

Yes, it is strongly recommended to use water as a coolant when drilling with diamond hole saws on hard materials like granite, marble, and porcelain. Water cooling reduces heat buildup, prevents premature wear of the diamond segments, and helps achieve cleaner cuts with a longer tool lifespan.

For a 3.5 inch diamond hole saw, a lower RPM in the range of 500 to 900 RPM is typically recommended when cutting tile, granite, or marble. Larger diameter hole saws require slower speeds to maintain consistent diamond segment contact and reduce heat friction on the material surface.

Yes, DI Tool diamond hole saws are compatible with standard drill chucks. It is recommended to use a variable-speed drill to control RPM appropriately for the material being cut. For wet cutting applications, a drill rated for wet use or a drill press setup with water attachment is advisable.

The DI Tool Diamond Hole Saw is listed under SKU 12708-1. Pricing starts at $47.51 and varies by size selection. The 3.5 inch diameter is available in the Straight Rim style, which is standard for larger sizes in the product lineup. Contact DI Tool for specific pricing on the 3.5 inch option.

While some diamond hole saws support limited dry cutting, it is not recommended for hard materials like granite, marble, or porcelain, as dry cutting significantly increases heat and can degrade diamond segments rapidly. Wet cutting with consistent water flow is the preferred method for achieving accurate, clean results and prolonging tool life.
