How to cut 3mm MDF board?

[nagumuthu]

Hello Members

I have to cut a rectangular opening on 3mm MDF board for exposing the power points behind it for usage.

Can you please recommend tools for cutting such a thick board.  Probably on knife, need to repeat few scores for the detachment. Looking for any other tools to do the job.  Not sure circular saws will leave the cut with imperfection for aesthitic appearance.

Thanks

Hello @Noyade 

The job was completed using Knife and it worked well. Plan B was to buy the router, if it did not work well. But I prefer to use router, as it is a hard work with knife.

Yes it is hard but well done! 😁

Hey @MitchellMc

Thanks for the advice on getting those tools, will surely look into them. At the moment I have a small handheld mechanical saw at home so maybe I will try that out first. But if I have to get a jigsaw or grinder to cut mdf, I will need to clamp it down. What vice do I need to use to have the mdf clamped down flat on the table? I don't want to be using a regular bench vice and having it suspended it air. This will mean for me to turn the jigsaw sideways and use it so I won't be able to get a clean straight cut. Newbie as you can imagine Please let me know.

Welcome to the Bunnings Workshop community @Curious96. It's wonderful to have you join us, and many thanks for your question about clamping timber.

For clamping a flat MDF panel to a tabletop, I'd recommend picking up a couple of these quick grip clamps. Pop one on either side of the board, clamping it down to the table. You'll want the area you are cutting as close to the edge of the table as possible before you actually start cutting into the table.

Please let me know if you have further questions.
