What type of cut(s) would you be making on the MDF? Straight cuts, curves - large or small, etc? MDF can be cut on a table saw blade, sanded on a belt sander.

My father had a cabinet mfg business for years and used MDF and laminate almost exclusively.I gave him a call and he said a "plywood blade" would be best for a jigsaw.

I would use a fine tooth blade. For 1/4" mdf you could also use a metal cutting blade at 14-18 teeth per inch. There is also a "scroll saw" blade that is about 1/8" front to back as opposed to the standard jigsaw blade that is about 1/4". If you want to cut small radius then I would use the scroll saw blade, but if you are just making straight cuts a wider blade will be easier to keep straight.

You did not mention if the Jigsaw you are referring to is hand held or a table jigsaw. That make a big difference in your question.

To bad this guy refused to answer the previous question on type of cuts.

If it is a straight line, then just buy hand held circle saw, they are cheap, and get a straight guide with clamps.

Agreed. I use metal cutting blades often for cutting plywood with a jigsaw. Wood blades have a tendency to splinter the wood. If you are cutting curves, go very slowly and don't apply too much forward pressure. This causes the blade to drift. The cut may look perfect on top along your cut line, but the edges will be slanted and the cut way off on the lower side.

Also, for straight cuts, you can get an edge guide for a jigsaw, or attach a fence guide for a dead straight cut.

A little off topic but just my two cents. I think a lot of new woodworkers buy a jig saw as their first power saw. As pointed out above a skil type saw is a much better choice. I don’t remember getting my jig saw out of the box in the last ten years. The tool is just not the best way to make the best cuts for most projects.

I agree Gimpy2, my most frequent saw I use is my bandsaw, second is my table circular saw.

Doesn't cut curves worth a darn.
