Best all round Jig saw

Hi,

I am a mostly interested in building electronic enclosures and robot chasis out of sheet metal. However some times I do also need to do home DIY and some carpentry also. I can not justify purchasing multiple tools. My metal cutting needs seem to be within spec of all the Jig Saws : less than 5mm in mild steel and less than 10 mm in aluminum. While I am tempted to select the GST25M I am not sure how will it will serve me for wood work. I am also unable to determine if it has an adjustable base angle. On the other hand I am unable to find a reivew of how well the GST 140BCE is suited for metal cutting. I would like a jig saw that is good at making accurate straight and curved cuts in metal and is a versatile multipurpose tool.

I would be grateful for you comments and suggestions.

regards
B Thomas

  Hi. I have the GST 140BCE and used it recently to cut out a rear derailleur hanger for a bicycle. The material was 6061 aluminium and was about 6/7mm thick. I set the saw up in a jig so I could introduce the piece to the blade rather than push the saw - the turns required are quite intricate. I got through about 6 pieces before I got something I was happy with but that was due to my low skill level than anything to do with saw. The actual cutting was effortless - I just kept misjudging how quickly it was cutting and going inside the line. Once I'd set the speed a bit slower all was fine

I used the stock metal blade that the saw came with but there may well be a better blade available. The correct blade is more critical than the type of saw imo. I hope this helps

I've always found that aluminium seems to clog standard metal blades really quickly, leading to rapid "glazing" of the cutline.  For the cutting I've done in which the grade of alloy is unknown, I've found that coarser blades do best in thicker extrusions.  I've even resorted successfully at times to wood blades.

As for the type of saw to buy, I guess it depends on your intended useage.  Any old saw will cut wood.  If you want the extras you'll have to pay for them.  All professional saws these days have pendulum action. Some, like my old ELU,  have had the feature for 30 odd years now!  Other desireable features, like tool-less soleplate tilting, quick release blade eject, LED lights, dust extraction etc. really are merely "nice to have" features rather than essentials.

If your metal cutting will comprise 80%+ of your cutting, or if accuracy in metal is of paramount importance, then get a dedicated metal saw.  You can always pick up a good second hand saw for woodworking at a later date for a fraction of new price.

In my experience a jigsaw is a seldom used item, in that it's used only intermittently, and then only for limited periods.  Any reputable brand produced within the last 20 odd years will provide performance 98% as good as it's contemporary equivalent.  As previously mentioned, it's more to do with the blade than the saw in relation to cutting performance these days.

Some great replies here already. The GST 140 BCE is great if precision is needed. It boasts 30% less blade deflection compared to the already well regarded GST 135 BCE. If you only going to be using it on metal then you can probably save a bit and grab a dedicated metal jigsaw. The GST 25M has been optimised for metal cutting.

The  Bosch JS470E  Top-Handle Jig Saw provides unsurpassed cut precision. Finish carpenters and kitchen and bath installers will appreciate the best-in-class 7.0 Amp motor and variable-speed control, making this saw an excellent choice for curve-cutting.
