Ok, so lately I have been rough-cutting lots of hard abrasive materials (thick phenolics and other composites) with my jigsaw. Lots of cutting time means lots of time staring at the blade, pondering blade dulling. Luckily we have gotten some carbide tipped blades which helps, but even carbide isn’t forever. So I have been trying to figure out what technique will most improve blade life. For example, more feed and less blade speed should decrease heat generated and increase blade life. But, how about the blade orbit setting? It seems like a 2 (out of 3) setting works well for this application and requires less effort than 0 or 1 to push through the cut. But does the impact of the orbiting do more damage to the blade than the reduced force does good? What has been your impression of killing jigsaw blades?
