PCB nibbler tools
I,m looking for a hand nibbler to fabricate cut outs in homebrew PCB,s , i know theres a few different designs out there , just wondering what anyone else has used or heard of in the good tool department.
Thanks. |

I avoid this as much as possible. I’ve tried everything. Fretsaw works but the blade lasts about two minutes! I do use aviation shears successfully on FR4 board though for initial cut.

One of those thin cutting discs in a Dremel.

cutting discs or a quality mill bit on a Dremel or similar tool.
A stand is recommended. You can also get a "plunge" adaptor to convert the Dremel or compatible into a miniature router for under £5 on eBay. Even comes with some milling bits. I use a tile cutter with a deck, abrasive wheel and water bath for thin sheets of alloy, plastic, mdf and hardboard as well as cutting up sheets of any kind of PCB or tufnol. |

Ok thanks for the feedback. Not an easy solution. In the past i have always used hacksaw but looking for another solution . Straight metal shears look pretty good .

Despite the Italian it's from China. IMO the only decent way to cut PCB sheets up is the tile cutting wheel with water bath. I got one originally, a plasplus, to cut quarry tiles and later got one with a metal bed. I think the cutting wheels are like some angle grinder wheels. Does a nice job of thin steel or aluminium sheets. Plastic is tricky. Thin MDF & hardboard can be cut too (best dry with no water bath). I did have the use of an X Y Z computer controlled mill that used a sort of heavy duty "Dremel" style drill in my last job. It was a kit. First task was to mill the working bed. We used it to make 0.8mm fibreglass "PCBs" by drilling guide holes for pins first and then milling both sides. Then drilling holes. Eagle -> Plot file -> Utility -> PC Windows special application -> Controller in the mill. I wish I could have kept it. However it means I'll only ever order in PCBs or buy one, never etch at home ever again. Actually not done home etching for maybe 30 years. First attempt was using mum's nail varnish as resist in about 1971. |

I used to use a hacksaw with the PCB laminate clamped to the edge of a bench, but for some years until recently, I've used an electric tile cutter with a 75mm diam diamond wheel. The model is 'Plasplugs Compact Floor & Wall Tile Cutter Model DW082'. It has a powerful 300W motor and runs at 4,600 RPM off load. I bought it at a car boot sale for a fiver some years ago. They're often on Ebay, Gumtree and at boot sales but many are the larger 'XL' models, which have a water reservoir. The 'Compact' just has a dust collecting box, the lid of which lifts off.
It's served me well, but I've recently built a small PCB cutter using a 12V motor, a 50mm diamond wheel and a small variable speed controller, having seen a similar ideas on youtube. I'll write another thread about that. Pic 1 is how I used to cut PCB laminate with a hacksaw. (I cut aluminium and steel sheet like that too). Pic 2 is the Plasplugs tile cutter with the dust cover removed showing the diamond wheel. Pic 3 is the cutter ready for use. Pic 4 is the maker's label showing the data. The only slight drawback is the width of the cut. Most PCBs I make are quite small and if say I have a piece of laminate 200mm wide and want two 100mm pieces from it, the diamond wheel takes maybe 5mm out of it. Apart from that, for the occasional PCB, a tile cutter is probably the least hassle and give the cleanest cut. Hope that's of interest. |

What I've tried last was a hand tile cutter ( or rather scorer) designed for wall tiles. I score the laminate side as deeply as I can and then cut with metal shears. The score keeps the cut line to that made with the score.
