How Do U Drill A 4" Wide Hole

[gonejah17]

I need to drilla 4" wide hole in the side of my cab but dont have a tool to do it. I want it to be a perfect circle. Any suggestions? Cant find a hole bit that's wide enough. thanks for any help.

They sell drill bits that exact size at Home Depot for about $12, and you need the adaptor for your drill--another $10. This'll come in handy, as you can use the adaptor for the many sizes of drill bits they have.
Or, you can draw a circle and hacksaw it.
If you can't get your hands on any of those tools, then you need to invest in some home improvment products!!

thanks man!! I have some bits like that but only up to like 2 inch diameter. I couldnt find any 4" online searching them but I figured they had to be out there. Are they called hole bits?? cuz I swear i googled 4" hole bit and came up with nothing.

hole saw

A 3" hole saw cost me about 60 bucks.

A 3" hole saw cost me about 60 bucks.

What? Is that with the drill? mordgrow my brotha, you need take your time shopping for tools. But if I had a woman like yours, I would be in a rush to get home as well.

cmon guysssss wheres the efficient hardware knowledge tips? what you're going to need my man is a paddle bit. it looks like the paddle of a canoe, with flanged bladed ends and a sharp tip

[Rumpleforeskin]

I have never seen a 4" paddle bit.

[Mr.GoodStuff]

That would be the beastiest paddle bit ever... Straight INDUSTRIAL sized!!!

Hole saws would work better anyways for plastic.

My 4" hole saw cost my $20, just got it last night actually so this thread caught my eye.

The guy who taught me how to build a bio-bucket (river system) had this great idea of using screws to hold the basket underneath the lid and have a smaller hole than the basket so it kept the light from getting through sides of the basket and into the bucket. He used metal bolts though which I thought was rather uncool for use inside a bucket with water- so I bought nylon bolts instead that won't rust.

Hole saws are really cool but get expensive... I've spent probably $80 on them trying to find the right sizes. Gotta take one back actually... Kind of a waste of $10 if I never use it.

ive found that using the "drill" in the middle of the hole saw shatters some plastic that i work with (or maybe its just the cheapass drill i use?) i havent tryed it with out (using just the hole saw) but im going to.

btw, i paid like 60 bucks for the whole set up, the drill, and adapter and a drill bit, like a combo deal.. but yeah, still got raped

[gonejah17]

got one. perfect

Try using a hairdryer or (carefully) use a heatgun to *slightly* soften the plastic then use the drill on LOW speed. After a couple of tries on some waste plastic you'll get a feel for just how much to soften the plastic so your drill gets a good *bite* without being too soft.

You'll get a very clean hole but you'll need a variable speed drill.

How hot is your hairdryer that it can partially melt plastic? Maybe you have thin plastics in your area. My ScrOG Box has a thick thick layer of plastic, I could never melt it with a hairdryer.

It won't. The idea is to get it WARM. Once it is warmed up it won't have that tendency to crack like you don't want it to. No.. My hairdryer won't melt any of the plastic in my house either except maybe plastic wrap.

Heat guns are better though. You can usually pick one up in a hobby shop for around $20-40 (they have other uses like stripping paint and such as well)
