![]() For planing and chopping, the kerf only measures how much material is wasted.įinal Thoughts - Best Circular Saw Blades in the UK The kerf is less important - it describes the thickness of the channel a saw blade will produce as it cuts through materials. Most of the saw blades we review below are 20mm, though two are 30mm. The former varies widely, while 20mm is the standard bore depth. There is two main circular saw blade measurements to be aware of - the blade’s diameter (which affects which machines it’ll fit onto) and the bore size (how deep it can cut). Abbreviated to TCT, these blades can last up to 50 times longer than conventional steel blades when slicing through harder materials. Most teeth lean forwards (a positive hook), though some are double-ended, facing forwards and backwards (both positive and negative).īuyers should pay particular attention to whether circular saw blades feature titanium carbide tips. Plywood blades are the ultimate example of fine cutting, with up to 160 teeth per blade ensuring splinter-free finishes that won’t rip this composite material during cutting.
