Tools for cutting fibreglass

[AllanJ]

What are the best tools for cutting fibreglass to leave good edges?

Diamond disc in a small grinder

And for holes, the diamond or carbide grit faced hole cutters designed for tiles, downside is that they are only available in a limited range of sizes.

If you are doing a lot, I really find the Excakt saw the best tool on thinner panels of all sorts of material, especially in situ.

Thanks for those. Hopefully the panels will survive my attempt!

Jigsaw with a metal blade gives me a clean cut at work, eats the blades though but as i dont need to cut a lot its fine for me

I've had great success with a carborundum coated jig saw blade.
Available from Fibeglass suppliers not expensive and does not wear out.
Best to cover the FG with making tape or similar to prevent dirty marks if you are working on a finish surface,.

Router with good carbide tipped bits and a little surface polish on the tools to stop any build up of debris.

I use a dremel with a heavy duty cutting disc. I like some of the other replies though and would also consider them depending on the hole size and location.

Generally any of the above PLUS a vacuum cleaner to get rid of the fibreglass dust that will be generated.

If you get fibreglass fibres on your skin it will itch like hell.

Have a COLD shower and slide a cake of soap over the affected areas. Discard soap after.

Do not have a HOT shower as this will open the pores in your skin and allow the fibreglass fibres to penetrate deeper.

From one who has learnt the hard way.

Make sure you use the right type of dust mask. GRP dust is very fine and abrasive, so you do not want to breathe it in; it's probably the next best thing to asbestos!
