DIY: Granite Cutting


Granite cutting is not a typical DIY project. It involves special tools and equipment along with a knowledge of stone structure. Granite is cut for countertops, tiling installations and various other projects like granite bar top installs or the creation of granite statue bases and bookends. If you are considering starting a DIY project that involves granite cutting, make sure you have the proper tools and basic stone-cutting knowledge.

Tools Required

  • An important aspect of any DIY project is the tools. In granite cutting they are especially important. An ordinary saw simply will not cut the granite. Use a high-powered masonry saw or stone cutter. A diamond bit blade or one that is designed to cut granite is also a necessity. In addition, the proper lubrication is required. Without this, your blade will not function properly. The friction involved with cutting granite produces an enormous amount of heat, enough to warp and break your blade and damage the saw.


  • First, set the granite on a stable cutting surface, once that supports the granite properly. The two granite pieces formed by the cut must each be supported so they will not fall. In addition, for interior cuts like sink holes, position the granite so the area closest to the cut is supported. Stress produced by a new cut into the slab will produce a crack if the stone is not properly supported. Always use caution when attempting a cut, and position yourself so you are not under the granite or in the path of the saw blade.

Types of Cuts

  • There are many types of granite products. Granite tiles are cut with a stone tile saw, while a countertop slab is cut with a larger wet saw or stone saw. The cutting of tile is much faster than the cutting of a countertop slab, and a more powerful saw with a larger diameter blade must be employed to cut the thicker slab. Otherwise the results will be inferior. Learn the basics of a wet saw before you attempt any type of granite cutting. Higher quality lubrication and bit materials will always give you a straighter and faster cut no matter which type of material you are shaping. Metal abrasives used in cutting blades are as varied as the types of granite you will encounter and too various to list here. Selecting the right ones for your cut is as important as the process of the cut itself.
