Question about Bosch T101BR 4 Inch 10 Tooth Jig Saw Blades
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!
