I'm in the market for my first plunge saw, I'm obviously getting a festool. What are the advantages of either one of these saws. Normally I would just buy the 55 since it's smaller. But I have an opportunity to get a 75 for less than the 55. A good bit less. Look forward to some good opinions. Thanks. Sam
Hi Sam and [welcome] to The FOG.
As it happens I own both TS75s and TS55s. Each of us has unique approaches to doing the tasks we do.
Solid lumber is a major portion of every custom cabinet I make, but I do not build those on site and I have a large shop with all the fixed tools I need to machine solid lumber. Most of my use of plunge saws involved machining sheet material. Occasionally I do use 33mm or thicker sheet material. That is within the theoretical limits of a TS55, and before the TS75 reached North America, that was how I broke down such sheets.
People I trust tell me they often use a TS75 to rip as well as cross-cut solid lumber. They have all their fingers, so doing so must work for them.
Maybe it is just me because I had been using TS55 to precisely break down sheets of cabinet-quality plywood for several years before I bought that TS75. For me when working with plywood from 3mm to 19mm, on a guide rail the TS55 seems a natural. I consistently achieve a better than 'glue-ready' cut.
Try as I might, I have not been as happy with any of my TS75s making cuts of less than 25mm. I do not know if it is the blade deflecting of what. For me cutting thinner plywood or chip material is not best done with the larger blade.
On the other hand, if I could only have one plunge saw and occasionally needed to break down sheet material thicker than 25mm, I would recommend starting with a TS75,
As for getting such a bargain because you have found a TS75 selling for less than a TS55, good luck. My experience is that the savings will be soaked up by the more expensive TS75 blades with a higher re-sharpening cost. Chip one TS75 tooth, then tell us about the savings when replacing that blade. Even if you have the sweetheart quantity grinding discount I enjoy, you do not want to think about repairing TS75 blades.
Still, if you need a TS75, then by all means purchase one. If you can buy TS75 blades at a deep discount, you might want to double check they are not stolen.
