Keep TSC 55 K or upgrade TSC 55 R to thin kerf?
« on: January 21, 2023, 02:36 PM »
I was thinking about upgrading my track saw to the new TSC 55 K for a while. Way more power, higher cutting speed, better dust collection... What's not to like? Ah, the absence of the riving knife which was replaced by the electronic gizmo that would stop the blade if the saw comes off the track. I can live with that if my saw has 50% more power.

So right before the January Festool price increase I pulled the trigger. The new saw arrived very quickly and I instantly got it out and compared it to my old TSC 55. To my utter disappointment, it was exactly the same saw! Same base plate, same housing, same motor, same plunge mechanism, same miter settings, same blade arbor flange and bolt. The only difference was the new electronic kick-stop system, thin kerf blades and battery gauges were no longer on the motor housing.

Since the motor is exactly the same, the "twice as fast" feat was only achieved because of thinner blades! The tool itself is identical. I felt ripped off.

What stops me from using that same thin-kerf blade on my old TSC 55 REB? The 2.2 mm riving knife, that's what. But wait a second, isn't a 1.8 mm riving knife available separately as a part?
Of course it is.
It's a part that cost $23 plus shipping.
So I got the part, fitted it to TSC 55 R and compared the speeds. Both saws cut exactly the same. Definitely much more powerful and way smoother than a 2.2 mm blade! Dust generation was reduced by 60-80%, it was mind blowing.

Here is the dilemma... Do I return TSC 55K and spend $30 (part plus shipping) on the new riving knife plus $84 for the fine cut blade or do I sell my current TSC 55 R and keep the TSC 55 K? Monetarily it's a wash. It comes down to riving knife vs electronic kick-back stop + 3 year warranty + nicer sys3 systainer (yeah, it's way better organized inside for the track saw).

What would you do and why?

A few pictures to illustrate the TSC 55 R conversion.

Old and new riving knives side by side. Old one is easily removed by unscrewing those 2 fasteners by the arbor. Carefully remove the spring and you are done.

I'd keep both. The R should have earned her money by now, so it's nothing wrong with upgrading to the more recent K - and keep the R - with or without conversion - as spare/second.

The 1.8 mm riving knife is from the HK/HKC? No noticeable slippage of the thin blade on the R?

Kind regards,

I thought about it. Small shop, lack of space. If I keep the K, I won't have space for another tool.

Nope, it's from TS 55 F. No slippage at all as both machines are identical. Same arbor, same arbor flange. The 1.8 mm blade is 0.4 mm thinner on the cut-off side, not 0.2 mm thinner on both sides if that makes sense. So it fits all my tracks perfectly as well, I don't need to replace the track strip.

Since you consider the price as a push, I think a lot depends upon how you use the saw.
If you cut solid wood a lot, the riving knife might be better. Sure the safety aspect of the electronic mechanism might be equal to the riving knife, but it is literally not down there holding the kerf open. Most of the tie, this may not be an issue, but that one time where the tension closes in on the saw, the riving knife equipped saw may just keep going. You do still need the cut completed after all. The electronic version stopping the kick-back is fine, but it doesn't complete the cut. You may be able to wedge the kerf open and keep going, but do you really want to?
 If you use the saw for sheet goods, the newer version seems better. Sheet goods should never give you this kind of problem.
Personally, I would avoid the conversion, unless it comes directly from Festool, because it would undoubtedly void that 3 year warranty that you just paid for.

Wouldn't the arbor/flange have to move the blade closer to the track by .02mm to keep it the same?
If the blade was just narrower, the kerf would move out that far, wouldn't it?
Certainly Festool doesn't off-set the blade?

They sell shim versions (for table saws, and I would assume for track saws).  The shim version is used to allow exact cut measurements with various blades.

A google search should yield information on that.  These are fairly cheap.

I just looked on Home Depot and they have a “blade match” shim package for 5/8” arbors for $15.00.

I am not sure where to find shims for Festool arbors.

I'd return the electronic version that does not have a riving knife.

What was the part number? I found 10037341. Asking for a friend

Hi, the plate rests against the clamping flange no matter what kerf size.btw been using both my ts55eq and r with new blade for a while i worry of deflection when they began to wear,has not happened yet.

I did some searching and it seems that's the correct part number for the riving knife from the TS 55 FEQ-F (1.8mm). Strangely, I can't find it in EKAT from Festool US. Going through the main festool.com site, it's under the FQ model.

The 'track side' of the blade doesn't change position just because the thickness of the blade changes, as long as the offset between tooth kerf and plate thickness is the same.

That's what I was getting at. Is it the same?
I don't know, I have never used or even touched the newer version.
