Best fine finish blade for kapex

[Mbconstructionjoinery]

Hi all looking to pick up a new fine finish blade for my kapex just wondering people's veiws/experiences on which blade they found best either Festool or other brand for fine finish work with hardwoods and high gloss laminted boards (either one or multiple blades?)

I have been using the 80t Tenryu Miter Pro and the cut quality is extremely good with little tear-out on all faces in most situations. In my opinion it is better than stock in that regard, BUT.... the fling factor is magnified big time with this blade. It sends small off cuts flying about 50% of the time.

Can that be reduced with an auxillary wood fence?

Make sure that the blade is going all the way down. I adjusted the cut depth on my saw because from the factory it wasn't cutting quite all the way through unless you pushed pretty hard. After dropping it a bit I have probably 5% of the off cut flinging that I used to have. Not exaggerating at all.

This may not be what's going on with your saw, but it's worth a try IMO.

Does the Tenryu Miter Pro  have the same kerf as the stock Festool?

If not would it require a re-calibrations ofthe Kapex lasers?

Thanks

I use the 80 tooth Festool blade. Works fine for me. Tear out is almost nonexistent.

Thanks for the info guys it's tear out I have issue with using the stock 60t blade, it's fine making straight and mitre cuts but has quite a bit of tear out on bevel cuts. I was thinking of getting the Festool 80t but just wondered what others are using, not seen the Tenryu blades on any uk sites.

The materials you are looking to cut can require 2 and maybe 3 different blades.  For wood both unfinished and prefinished I run blades with a 4ATB+R configuration and 80 teeth.  They have a 20* top grind and a negative hook. 

For high gloss laminates your best bet would be a blade with a H-ATB grind. Very clean cutting in man made materials but based on the 30* or higher top grind the edge will wear quickly.  If you only need a clean cut on one side a blade with a TCG grind and a negative hook will give you a better compromise between cut quality and edge life.

It just seems to be the geometry of this particular blade, My depth of cut was where it should be out of box. Can't comment on thickness in relation to laser adjustment as I only use the laser to find an angle on a scribed line if need be. It's a shame the OP can't find it in the UK... Great Japanese made blade.

Unless there is a defect in the grind I can't think of a reason the ATAFR grind that Tenyru uses throwing off cuts any more or less than a blade with more conservative geometry.

I've run the 12" Miter Pro.  It cut cleanly but the edge life was poor.  The ATAF grind is all shear angles designed for cutting very brittle and fragile materials. It's not a great grind for wood.  The only advantage it has is on an under powered saw.  The shear angles allow it to take a very sharp edge reducing cutting pressure and for as long as that sharp edge lasts it cuts easier that a blunter geometry.  With regular cleaning the edge was still gone in about 2 weeks.  At similar price points there are any number of blades that cut just as cleanly and hold up better.

Check out the FS Tool LM 6250 or the Royce Ayr 16100800.  4ATB+R. .087 plate and .112 kerf. Cost around $130. Canadian made. Clean cutting with great edge life.  You'll need to get them rebored but that's not a big deal.

I've been very happy with the cut quality of the Oshlun 80T blade.  At only $60 from Amazon it is a bargain compared to the Festool and Tenryu blades.

Justin,

Who knows... all that I have said is that this  tenryu miter pro on the kapex cuts very well but unfortunatly has a greater tendancy to send off cuts flying compared the stock 80t blade. All i can comment on is my experience with the two. The grind that  Tenryu chose for this kapex blade would make sense based on your analysis because it is an under powered saw by comparison.... I'm just a finish carpenter, this has been my observation with this particular blade. I will consider the blades you mentioned and hope that the OP will also.
