Carvex 420 blades: what to use?

[farmmachine]

I have a Carvex 420 and have blade question.

The recent discussions about using Carvex blades to avoid deflection and circles being out of round, etc., has me concerned about the Trion blades I have being unsuitable to use. I have a multipack of blades marked Trion, with no reference to Carvex as is seen on blades now available. They were delivered through the same order I placed for the Carvex 420 (so I would have an ample supply). The blade supplied with the 420 is marked as being Carvex.

Are the current blades marked Carvex simply re-marked Trion blades, or different and required for the Carvex?

Also need the longest blade usable on the Carvex 420. Is that the 145mm and must those blades be marked Carvex for best results?

Regards,

The Trion blades are not suitable for the Carvex. Those blade are too thick and can get hung in the ejection mechanism and for that reason were discontinued and replaced with the Carvex blades. That said, all other blades will work fine in the Carvex and do not need the "CARVEX" written on them.

The best blade to prevent deflection is the CARVEX blade (FSG).

Yes, the longest blade is 145mm (4-3/4" depth of cut).

Shane, can you post a part number? When I search for FSG I tend to find something with TRION written on it in the picture.

Cheers.

There are multiple FSG style blades, both Carvex and Trion labeled, depending on length and pack quantity. Here's a list for you.

I have been using the trion fsg blades in my carvex 400 with no problems getting them in or out .

I hope this is not too off-topic.  I have been unable to get a thorough understanding of the meanings of the letters on the various Carvex/Trion blades, for instance I have 3 different S75/4 blades: S75/4 (with no suffix), S75/4 K, S75/4FSG.  And I have other blades that have an FS suffix.  What are the differences/what do the letters mean?

Thanks for your assistance

I've yet to run my Carvex, but ordered a pack of Festool 486546  S75/4 Trion/PS2 blades. Would I have been better off getting the 499476 S 75/4 FS Carvex version for general/straight cuts?

Here is a blade selector search function that Shane did for the Festool USA website.  It might give you some assistance:  http://www.festoolusa.com/jigsaw-blades

Don, I don't know the meanings either. They are German abbreviations.

Daniel, the Trion blades are problematic with the Carvex. The shank is slightly too thick and May caul use the ejection mechanism not to work properly.

Peter, I appreciate the heads up; I frequently refer to that link from Shane, and find it quite useful.  The interest in the meaning of the suffixes is probably just academic.  Prior to retiring, having spent the last few years as a consultant to automotive manufacturing, all aspect of most all part numbers carried specific meaning or information, and I was just curious as to the meaning of  "K", "FS", "FSG", or no suffix, that's all.

Thanks

Thanks Shane,

On my Carvex 420 I have been getting very slight blade deflection while doing curvy cuts.

Blade used is the S75/4FS.

I do not have a splinter guard installed. The metal guide is tightened still allowing the blade to freely move yet is close enough that the paint has been worn off - I remember Shane in another post recommending that the guide be set this close I think.

The deflection only occurs in hardwood stock, for example, Maple at around 8/4 thickness.

I am thinking the tight curvy cuts in that hardness wood and thickness is probably testing the limits of the saw.

Thanks

8/4 maple is certainly going to test the saw in curved cuts.  But try the FSG blade. It is a better choice for curved cuts because the teeth are set to the outside helping to clear the kerf.  I would also think that it should be better without a pendulum setting. The FS blade teeth are set flush with the blade body so in a curve there will be little room for the blade to turn, and stressing the blade is likely to cause deflection.

Good advice, thanks.

I will try those blades.

It works great with 3/4 no problem. I won't be doing at lot of 8/4 cuts in hard Maple anyhow.
