DEWALT DT2361QZ 152mm Recip Blade Metal 3-8mm 5 pack

First, ensure that the blade(s) you’re thinking about buying are suitable for the kind of material you’re cutting. Some are designed specifically for working with wood and others for cutting metal. Then you have ‘all-rounder’ blades which can get through various different material types.

You may wish to check the material used to make the blade(s). ToolStore UK offers blades made from High Carbon Steel, High-Speed Steel, Bi-Metal and Carbide. Each has its own properties and is best suited to specific jobs.

Another consideration is the number of Teeth Per Inch (TPI). The higher the TPI, the smoother – and slower – your cut will be. The TPI of individual blades can range from 2 (for rough cuts in wood) up to 24.

Finally, think about the blade length you might need. Shorter blades tend to be very strong and provide straighter and squarer cuts, while longer blades have more flexibility, making them useful for flush cuts. As a rule of thumb, your blade should be longer than the cut you need to make.
