How do they make a nice square hole in wood (1 Viewer)

[Wagoneer]

It's always puzzled me how manufacturers and dealers manage to make a square or rectangular hole with nice rounded corners in wooden panels.

I guess they must use a metal template and very fine/narrow blade jigsaw.

It gets even more complicated when you look at floor hatch covers where the mating surface includes a lip. I can only assume they must make the hatch cover separate to the hole in the floor.

It's all a bit of a mystery to me but expect some of you knowledgeable funsters will know.

If you're doing it by hand you use an appropriate diameter drill to make the four corners and a jigsaw or coping saw to cut the sides.

But surely you'd get it from elsewhere to save some pennies!

 

[mpdcymru]

Yea, a B&Q square drill from Screwfix.

Manufacturers don't use templates all done on computer controlled routers.

 

[funflair]

As above CNC machine.

They can send a man to walk on the Moon,

but they can't fit a round peg in a square hole!

Still no answer to the basic question, how do you make a square hole with anything that is rotating, computer controlled or not, rotating cutters make round holes?

If you're wanting a square hole without rounded corners you still use the same method I described above.

You use a mortice machine that has a drill bit that fits into a square hollow chisel .You drill the hole as the chisel removes the corners to leave a square hole .lol

Would that work on metal?

Still got rounded corners!

The OP asked about square holes with rounded corners. They use router bits, which drill through the wood and then cut it when pulled sideways. It is either done using computer controlled cutting machines or a simple template which is clamped onto the wood and which enables the cutter (which has a none cutting shoulder) to follow the outline to be cut. Simples.

OK then how do they make square holes in metal with square corners?.......or shall I start a new thread

 

[daveandsan]

When a square hole was required at work, a round hole was drilled and then a drift that tapered from round to square was pushed or pulled through the pilot hole.

But.... did they?...

With a square punch in a bench press or laser cutting is the way it's done these days.

With a milling machine. Or use a drill and Trepan

Milling machine uses a rotating bit,trepan rotates, all rotation causes curves.....back to square one?

Broaching

Broaching

Thank you.....no rotation then, brute force

Not so, Rotary Broach doesn't

How so, the one you used as an example was pushed through without rotation?

Because that was a press broach not rotary broach, it wernt aimed at a particular post just an example.

Further explanation required.....rotation makes round, I can see with some form of offset deltoid type arrangement an almost square hole could be made but exact?

Or a Plasma cutter!

Another example but drill square
