I do love a good forstner bit. They're excellent at clean cutting medium diameter holes, and the easiest way you can get a flat bottomed circular hole with 'norma'l tools.
Appreciate this new guide series, very handy for those of us who keep meaning to getting around to modding some of thoee things taking up room in the loft.
Pretty good guide. I think you should mention that it's a good idea to not hand hold the material when using a hole saw. It's better to have the material against something like a length of angle aluminum clamped to your waste board. This will keep the material from spinning violently if/when the saw grabs.
My tip for this article is to look at the tenants of your local industrial estate. There will almost certainly be a tool supplier there.
After all, if you just want ten 3.5mm bits, why buy an assortment?
As a non modder who's on an equivalent level to stick people drawing when it comes to anything diy/manual/etc, I enjoyed the article and found it interesting. More please
This was a bit of a good bit about bits on Bit.
Some useful info in case anyone can avail of it...
Old fashioned hardware shops are good for such things too. Probably have what you want lurking in a box or draw somewhere in the shop.
Currently typing that into a [searchable] word doc, if anyone is interested...
...why yes, I am bored, how did you tell?
Glass/ceramic bits are handy too especially with a lot of case manufacturers now using tempered glass, I got a nice little set earlier in the year for about €25 so I could pass a cable through glass. It's worth noting you need to put minimal pressure on them when drill though as glass shatters easily.
Wow this had quite the reception haha, looking forward to growing the series a bit. Could be an interesting idea to add some of the suggestions you've made in, seen a few ones pop up on FB too which could be interesting to include. Thanks for all the wonderful feedback, so glad to see it's welcome direction
You simply can't drill (or cut) tempered glass. If you drilled one, it was not tempered.
You can, but iirc you'll need to break out a laser cutter if you don't want the glass to shatter into a gazillion pieces.
Extremely thin ones, like mobile screen protectors, yeh, maybe. But haven't seen anyone successfully cutting tempered glass sheets used in windows/furniture/pc cases (3mm thick and up). If you have any such examples, please share.
Nice but no mention of cooling,drill techniques nor the importance of workpiece holding...especially with the holesaws?
Those charts are easy to find on the net. Most online industrial supply places have them up for quick customer reference.
Lube on soft iron: Lard or soda water. -And I feel silly for mocking people using beer for cutting coolant now.
So I'm risking sounding stupid hear but why soda water? I noticed it said that in the images of the book
VipersGratitude posted and now it's been mentioned again, so why soda water (aka:carbonated water) and not just plain old water.
It inhibits rusting.
