I am trying to cut 40mm thick Maple worktop with an oldish Bosch 450w

the saw keeps kicking/jumping off the work, despite my holding it
down firmly. I have a feeling that the speed of the blade affects
things, but can't find any information about it. Can anyone offer
advice? Someone has suggested to me that Festool FSG blades would be
better.


There is no way to get a decent cut through 40mm worktop with your
jigsaw - sorry :-(

You need either a circular saw or a router. Even a really good jigsaw
would struggle through that.


Agreed. Cut with a hand saw and use a router for show edges afterwards
to plane level.

By the look of it the T101BRF is too fine for this job. Your worktop is
probably sticky because of the resin, so you need a blade with a "wider
set". Get one that says coarse/fast on the packet, and use the saw's
medium speed. Go to a pukka toolshop if you can.
