Is MDF bad for saw blades?

Any circular saw or handheld cutting tool will make rip cuts or crosscuts in MDF, but the blade should be carbide-tipped, because the high glue content of the material dulls steel blades quickly.

Does cutting MDF dull saw blades?

For particleboard or MDF, it is suggested to use a triple chip grind blade with 80 teeth. Man-made materials can quickly dull saw blades. With a triple chip grind, the corners of every other tooth are chamfered at 45°. Number two would have to be a properly tuned saw.

Is MDF hard on blades?

A high quality blade will last longer than a low quality blade. There’s also more contact area and more friction in MDF because it’s continuous rather than having fibres.

To make straight cuts in your MDF, acquire a circular saw that has a cutting speed between 3,000 and 3,350 metres per second (9,800 and 11,000 ft/s). For the best cut possible, install a blade that has at least 60 teeth and a width of about 355 mm (14.0 in). For additional strength, pick a blade that has a carbide tip.

How do you cut a MDF with a circular saw?

How do you cut MDF with a knife?

You can score the laminated MDF with a knife, but you’ll need something more powerful to cut through completely. Keep a metal edge straight against the cutting line, and lightly pass the blade of the utility knife over the line, repeating until the laminate is fully marked.
