Cutting Hardiboard

72chevy4x4

The shears I've found cut hardiplank, but I've got trim boards (1" thick) to cut. I've found two different blades-one is a low dust Hardi-Plank approved blade with 4 small teeth and the other is a continuous rim diamond tip, similar to a tile or masonary blade, which can be used for fiber cement, brick, etc.. Does the latter blade create a lot of dust? Any tips on using a mist to decrease the dust, without getting electrocuted

Use the Hardie Blade, a hepa vac with your saw is the best

The best blade we have found to cut fiber cement siding and trim is the Hitachi Hardiblade, it will usually last us 5-8 houses depending on how tough you are on it. It does make some dust but not nearly as much as the continuous rim blades.

I also have the Hitachi Hardi blade and it works fine, but you need to get the right saw for the blade.

A Makita 5057KB, and a shop vac.

Ever see what Hardi's like when wet?

10" sliding compound mitre, 10" hardi blade, build a cutting table, cut siding and/or trim. Done.

No circular saws, no shears, just precision and ease of use over and over again.

Yeah,but what if you have to use a table saw?
I'm in a same boat.Doing same job.Hardi trim and siding.Started today.Bringing my shopvac tomorrow.Dust out of miter saw is not bad,but from a table saw,HUH.

What about a table saw? Use one! I don't use my nice Bosch table saw for it though as the dust breaks down saws relatively fast... I buy a cheapy Ryobi or the like (any saw you wouldn't dare bevel any rips with that are usually under $100) and put a 7 1/4" Hardi blade on it (you can use a 10" but way more expensive and hardie is thin enough that you don't need it).

The dust can be a prob but you could hook a large fan or whatever to blow the dust away from you.

I'm using an old 10" table saw with the hitachi blade and it cuts the 5/4 (1") thick hardi trim with ease!
