Hello,
Why are the teeth of this particular jig saw pointed downwards? Sorry, couldn't find a satisfactory answer yet.
A handheld jig saw machine jumps all over the place with this particular blade in it. I always thought that the sawing action should be in the pull-up stroke (pulling the machine tight to the board while cutting), not the push down stroke (pushing the machine away while sawing...) as controling the cut is much more difficult and there is a chance of breaking the blade or bending it. When the jig saw machine is in a tilted position the whole process becomes an ugly joke.......am I (non-professional) missing something?
Thanks for your help.
Hi, The reason for a down cutting blade is to see your cut on the finished side of laminates ( which include veneers, plywoods, plastics, formica . When using an upcutting blade on laminates the smooth cut is on the bottom, which you can not see till you are done and turn the work over. Reversing the teeth allows that smooth cut to be on the top. This is usually done on smooth flat surfaces as you have found out and does not work with orbital or tight scrolls. As far as the pushing or pulling, smooth cuts in laminates require the saw doing the work at a speed that allows the teeth to cut and remove material with biting. So if you are biting, (This is a much slower process than pushing your jigsaw through regular wood) check that you are not pushing too hard and that your blade is still sharp. Good Luck to you, this should Fixya!
That should have said, remove materials without biting. Sorry!
Hi, Frank, Dude you are shootin the messenger. You asked why it was like that and I told you why they make them that way. I am not the designer or the marketing exec. Whether I agree with you or not is irrelevant. I give free expert advice and answers on this site and my ratings indicate the level of that help. Unfortunately, I keep getting questions that people don't seem to like the answers to so they find them only helpful. Thanks

Hello Joboo1,
Thanks for your reply regarding the jig-saw blade.
I can see your point that the clean cut- without chips breaking off - will be on the visible side while doing the sawing on laminates, yet I am a bit amazed that a 'special design' blade is made for that purpose.
Why not turn over the board, draw the cut-track on the rear (rough) side and do the cutting with a 'normal' jig-saw blade? With the following advantages:
1) No scratches / damage to the smooth surface as the machine touches the other side.
2) Easier control for amateurs like myself.
3) No chance of 'buckling' etc. the blade.
4) Saw can be used for all types of materials...cost effective..
Thanks again for your time.
Hi Joboo1,
Don't be offended. I am very glad you give free advice and spend time on the web helping less experienced persons like myself to get on with the job...It is my interest in these things that looks for answers triggered by your answer.....thinking out loud...you should be flattered.....; yet I'm not that obsessed to contact the designer for this particular thing.
Thanks again. Keep up the good work.
Bye,
Frank
Hi, frank, the experts are rated by the solution ranking. So if they don't get the fixya rating it can actually work against them and bring down their rating.That's why we all try to get the 4 diamonds, it transfers to our standing in the community. I realize that some people give multi-solution answers , "2" diamonds thinking they are being fair, but it is a negative when an expert gets a 2.It is better not to rate than to rate low, and since most of the experts work for free, this is the only reward we get. Thanks
