I am in the process of finishing my kitchen installation and need to
cut the chipboard plinths to size.
I tried using a fine jigsaw blade but it still chips the plinth
I also tried scoring along the line with a stanley knife and again it
still chips slightly.
Can anyone advise me how I can cut these with clean cuts and no
Blades help a lot. Not just small teeth, but anti-chip shaped teeth
(Bosch 101B) and a new, sharp blade. Even better is a "reverse" tooth
blade (Bosch 101BR) that cuts on the downstroke. Make sure any
pendulum action is switched off. If your jigsaw has an anti-plinter
plate (tiny gap round the blade), then use that, although they're not
a great help on chipboard.
Scoring doesn't work too well on chipboard, because it's too hard on
the surface to score easily, and the chips are so fragile they''re
especially prone to chipping. Scoring might help if you can score to
the depth of at least half a chip thickness.
Another trick is to trim with a router, not a jigsaw.
Cramp a piece of ply or perhaps chip to the face side. Good and tight.
Then cut through the lot. No pendulum action. Sharp blade, Slowly.
Sometimes masking tape along the cut line is effective but a lot
depends on the quality of the core and the melamine face.

I prefer to use the blade design that is similar to a pruning saw or one of
the Japanese saws designed for cabinet work. These have no set on the teeth
and produce a clean cut on both sides of the cut. They cut on both the up
and down stroke and create the least splintering that I have seen even in
difficult materials such as chipboard.
