Re: Using TCT saw blade on fiber cement

Hi sir guad,

It would be a waste to sacrifice those good branded blades that you've mentioned since they are only for wood use. Sayang naman yuong mga talim ng mga blades mo. 😮

Anyway may I suggest that you look for this kind of TCT circular saw blade that I bought a few years back at Ortigas home depot. Brand is benz, a versa-cut circular blade for aluminum, wood, plastic, fiberglass and for steel. So I was thinking if this blade can cut through steel then why not fiber cement boards. Its a 7" X 60T-S, for angle grinder and circular saw. 😉

Actually I bought this blade for my 7" angle grinder that I might use in the future since I didn't have yet a circular saw before. I have not used it yet so I cannot say anything about its performance but maybe its worth a try if you could find one if you are not in a rush in cutting your fiber cement boards since the instructions says it can be used for metal or steel. I just can't remember how much this cost.

Sana naka tulong ako kahit sa maliit na paraan. :p

Re: Using TCT saw blade on fiber cement

I think may circular saw that intended for cutting fiber cement board, I've seen one used in cutting granite slab. Blade is similar sa mga ginagamit pang cut ng tiles.

You can used angle grinder then a 4" diamond cutting blade. I used Maxsell super thin, P599 each blade. Very dusty lang during cutting.

Re: Using TCT saw blade on fiber cement

Sir guad you got me curious on this one, your thread.

For your benefit and information since I said in my previous post that I haven't used or tried the circular saw blade that I was talking about, then here it is, I did sample cuts with my angle grinder a while ago for curiousity sake on a 3/16" thick hardiflex and doubled it to make a 3/8" thick fiber cement board and the cut was great, it was fast, smooth and clean.:p

I even tried it on a hardiflex 1/2" senepa fiber cement board and the result was the same, smooth, clean and no dust and no more sanding of the edges. The teeth of the circular blade looks unscathed and still very sharp.

If it cuts great on an angle grinder, what more on a circular saw where it is more stable and with a straight edge guide. 😎

By the way the price of the CS blade is php665.00, that was then, I don't know its current price
now.

Hope this could be of help to to you.

@guad

The equipment you are referring to is a concrete and tile cutter w/c actually looks like a portable CS in 4" disc platform. You may get them locally and the reliable ones are METABO and MAKITA. Priced normally around 4.5K w//c is almost the cost of your FREUD blades. This is also good for cutting through granite / marble and it comes with a water drip hose so it doesn't dust too much. Hope this helps.:p

Re: Using TCT saw blade on fiber cement

Thanks for the suggestions, very helpful. I will try to look for that Benz or similar multi-purpose blade next time (sounds similar to an Evolution Power Tools blade), and for that specialized concrete/tile cutter.

Good to know from the sample tests that a circular/rotating blade works well, so it is now just an issue of blade type and lifetime.

I have Bosch 4" diamond discs (P325), but ruled out angle grinder at first because I didn't want to cut freehand. But the suggestion reminded me that there is an optional accessory (for Bosch, it is called 'cutting guide with dust extraction protection guard' and matching 'elbow') that makes the grinder out to be like a circular saw. Will look into this. I hope it is available locally and at reasonable cost. Anyone happen to have this or equivalent for their angle grinder?

Re: Using TCT saw blade on fiber cement

Hi again sir guad,

Actually I myself won't recomend using an angle grinder for cutting your fiber boards specially when cutting long straight cuts, CS is still the most recomended tool. If in any case that the benz blade is not available at home depots maybe you could also invest in what sir willyfernando has just posted.

Actually its not a special tool because I have one that I used to cut my concrete pavers for my driveway. Since you said you have already a 4" bosch diamond blade, then I guess that's just perfect if you have this concrete and tile cutter. It is a smaller version of a standard CS of 7 1/4" and above. It can accomodate diamond disc of 4" and a 5". Brands available locally are Makita, Dewalt, Metabo and Talon. The Makita of course is the most expensive specially the cs for the 5" cutting disc. I inquired before at HAN's Tools, Shang in Mandaluyong.

---------------------------------------

This small version of a regular CS is very easy to use, the depth of its cutter can be adjusted up and down similar to a regular CS. Maybe you'll just have to make your own straight edge guide. Of course this is much, much better than using an angle grinder.

Re: Using TCT saw blade on fiber cement

last year i was looking for these blades for my hardiflex projects using the jigsaw...i keep forgetting ordering them online.

@ Rosy
Tnx for ur nod on my post.

@ Guad
a few tips:
Concrete/Tile cutter - specifically designed to cut cementitious and stone or aggregates, Straight cuts w/ ease and control. Cost effective with ample cutting power even for 18-20mm stone slabs. Safer and predictable.

Angle Grinders - versatile yet,. temperamental. High record of mishaps w/ diamond blades. Attachment or tool adapter as expensive as the tool itself. even w/ steady hands it isn't as comfy as a gliding tile cutter for plentiful cuts.

BTW.... I am a contractor by practice and i am presently using METABO w/c i bought for 4.5k at Machtools, inc. last January. So far I have cut 300 sheets of 18mm Ficemboard under the brand FLEXBOARD, w/c is one of the hardest and strongest in the market and so far it's still in top shape. :p Hope this helps.

Re: Using TCT saw blade on fiber cement

Sir Willy,

Where are those Metabo's made? Are they still made in Germany?

Last time I checked Metabo angle grinders in New Triumph still German Made.

However they also had Metabo products that were made in China already like drill bit sets.

Re: Using TCT saw blade on fiber cement

As identified in the Bosch angle grinder manual, the 'cutting guide' accessory that I was interested in is this:

Bosch 1 619 P06 514

But according to Bosch PH sales person, it is not available, so this option is moot. Anyway, holding the grinder when using this accessory looks awkward. Maybe it is not available because it doesn't work well so nobody wants it, who knows.

By mishaps do you mean the work being ruined due to slippage/loss of control, or the blade breaking, or the operator being injured?

It happens to be also Flexboard, up to 300 pieces, that I am confronted with, but only 1/4" thick. I don't know much about Flexboard except that it is what happens to be available here in province (no choice other than Hardiflex) and only in 3/16" and 1/4" sizes, and cheaper than Hardiflex. I know that actual thickness is way undersized compared to nominal. I don't know much about who makes it and where, and until your mention, didn't know how it compares to Hardiflex or other fiber cement boards.

Are these the concrete/tile cutters being referred to:

Makita 4100NH 4-3/8" Masonry Saw

Metabo TC 4110 Tile Cutter

@ Guad
These are correct. Makita costs 8k amd Metabo @ 4.5k. For your use get the Metabo. Mine is still German. It slices 18mm easily and has similar power as the Makita.

FLEXBOARD is a better brand of Ficemboard than Hardiflex from my experience. It has more Fiber strands and uses Green asbestos not the dangerous kind. Hardiflex has paper or pulp in their mix so it bloats most of the time once exposed to water or moisture. Price is a plus factor. You may get them from Clinton Commercial in Mandaluyong near the Rotonda towards the Makati bridge route.

Mishaps are injuries and slippage caused by Blade, Tool and Worker failure of w/c I have a personal experience w/ 2 of my workers. Apart from these accidents are the damaged materials from freehand cutting. We often forget the blade limit of w/c should run at a specific rating based on the tool that it was designed for.

Re: Using TCT saw blade on fiber cement

Sir Willy,

@ Moji
You may get your Metabo products directly at MACHTOOLS, INC. in Del Monte Ave. , going towards A. Bonifacio Ave. on your right. Look for the owner Nancy Yu, She knows me and she will entertain all your questions about Metabo. Just tell her i referred you. (Willy Fernando) All products classified as Elektra Beckum products are German made. That was the original Metabo tag. You could easily tell the china made from germany made. Incidentally, they also own the brand Torq. I get my Makita products from Rolin's Mercantile in EDSA Cubao in front of the Baliwag Transit terminal near ELEKTRO WERKZ. They give me good deals for my purchases. For instance the Makita 3612-C Router w/c Timber715 uses, is given to me @ P 21,400 only.

[HTML]Green asbestos not the dangerous kind.[/HTML]

the fact that it is asbestos it is certainly dangerous to one's health when inhaled..

asbestos particles cannot be "digested" by the body and so they remain permanently lodged in the lungs where they promote inflammation and consequently fibrosis or scarring of lung tissue..when inhalation is prolonged without any protection this will lead to chronic obstructive pulmonary disease when lungs will have limited capacity to expand..

although there are a few types of asbestos they are all in essence can incite a long term inflammatory reaction within the lungs because they are not inert like for example a stainless steel metal to correct bone fractures...this prolonged inflammatory reaction can lead to severe permanent lung injury and worse...you develop mesothelioma...a type of lung cancer due to asbestos particles...it is an occupational hazard.

if you talk of the green type of asbestos then thats the most dangerous in fact.

i hope our contractors out there provide the necessary protective equipment to the workmen...in the philippines, to economize is the law...and of course most of our workmen are illiterate and do not know about these things...especially when they are young and physically ok...the effects usually from these harmful chemicals and the like has cumulative effects and may take years to be noticeable...kaya nga most of the painters, tile setters have thin physique...mukhang me TB...lungs are most vulnerable organ to these occupations.
