With plexiglass that thin or a little thicker than that you can just take you're drill and have the bit spin backwards to burn through it and if you do it that way without too much force it'll work every time
It’s interesting that with the same drill the common drill you didn’t put it down on the plywood or the wood whatever the same way as you did the other one, you held it up with no pressure on the back, and therefore it was more likely to fail, just an observation, not here to cause any waves.
Im glad I found this video, because the comments not only told me how to do it, but how this video was doing it wrong. Enjoy your damn algorithm engagement from my comment you monster.
In my grade 9 shop class (1976) I cracked some plastic sheet while drilling a hole. My shop teacher took the drill bit over to the grinder and ground down the face so it ‘rubs’ the plastic / plexiglass instead of biting into it. Worked like a charm.
a regular split point (130-145°) drill bit will drill acrylic just fine. it's better to use a slow spiral or straight flute drill bit so it doesn't attempt to pull the bit through the sheet. you should always drill with a solid backing (table top, aluminum flat bar, anything that the sheet can sit on or against without moving around) if possible.
The plasic bit is smaller giving it additional advantage over the larger wood/metal bit. Still think special bits would be beter then increasing whole sice a 32nd at a time
Rubbish. There's the obvious point that you had no support behind the first one so of course it's going to move around. Also, you used a larger drill bit on the first one AND you punched it all the way through and wiggled the drill back and forth. Pointless.
Well yea if you turn and jamb it like he did at the end of course you’re going to fuck it up. Smh.
Put a piece of painters tape over your desired drill spot. Slowly drill with a gradual force until you have successfully gotten through the material

That's some true knowledge if I've ever heard it👍
Thank you! I'll give that a shot definitely
😂 Looked like a clean rounded hole to me on the "standing up" non supported piece, THEN you showed a busted out hole!

just turn your dril Direction to reverse when drilling plexiglass not need special tools
The trick is to have it flat like on wood and use a step bit.
I want to cut out shapes in to these plastic planner discs. Would using a dremel work?
Not to mention he didn’t even support the plexiglass when using the regular drill bit

Would it do that if one were to drill a hole while the sheet is supported underneath, like in the second part of the video?
If you’re not using a plastic drill bit, yes, it is way more likely to crack, supported or not!
@@tapplasticsprove it.
@@wahmhofftechnologies6621Go find out yourself. Acrylic, especially thinner varieties, crack very easily when drilling.
I can’t remember parts of my school D&T days 😅 Do we need to cover the top with another sheet or something to make it better?
Burn (reverse drill) and dont push down. I burn-in wood that may crack or split. Tape will keep scrap from scatching unsealed plastic.
My man here selling snake oil, or should I say, snake bits?
I did .. it broke ... lol. did he shape the drill bite first. ???
Which drill bit is that
what a bias comparison 😂 unsupported , rammed the whole bit and swirled it
use a dulled bit.
Ha ha its the technique that mattered
what kin of drill bit? for wood or for metal?
I have also same question
I saw it on Amazon, plasdrill bit. It's special for acrylic and lexan
Music name ?

Looks like user error for a video to me. Maybe learn how to drill without purposely rocking the drill at the end.
We’re demonstrating the user errors that happen most often- we’re glad you noticed, and hope that beginners will appreciate the tips!
