40 or 60 tooth circ saw blades

[scooby]

On a previous thread I was given a link to the Summit saw blades website. I can't remember who it was on here but thank you

My saw is a Hitachi C7U2, which uses 190mm blades. At the moment its got a Freud pro 24 tooth general purpose blade but I thought I'd try a fine (40 tooth) or extra fine (60 tooth) blade.

I've been hanging a lot of doors lately, the majority of which needed reducing in height a lot (hence the need for a good saw blade).

My only concern with the 60t would be the possibility of putting a lot strain on the saws motor?? As said the fine blade will only be used for doors (however I seem to be hanging a lot of oak doors lately) and sheet material (ply & mdf )

For the rougher work I'll be reverting to the Hitachi blade (18 tooth)

So, 40 or 60? Thanks

Scooby I have got the Triton 235mm 2000W motor and I went from a 24 tooth to a 40T and was very pleased with the results. Yes I had to run the work a little slower but I was not prepared to keep changing the blade. I also bought a 60T tripple cut blade but that requires you to slow the work down even more and your saw needs the grunt to work well. The results were alot better but I got burns while trying to get the speed right. With more practice it would be better but as the only blade in the saw , I think that the 40T is more practical.

Assuming your doors are solid oak then the majority of the cut will be through the top or bottom rails and will be rip cuts, only crosscutting the ends of the styles. So you will find it easier with less teeth and a rip profile tooth but there is more risk of tearout on the crosscuts.

If you are worried about the saw being overloaded then think about a thin kerf blade, CMT do a good range in 190mm dia and I use a dewalt one with 1.8mm Kerf. Also cuts down on the sawdust.

Did a dozen veneered oak doors the other week and used my router and a multitrim bit to trim the bottoms gave a good clean finish.
