Notcher/holesaw

Post by **Wooders** » Tue Dec 16, 2003 2:32 pm

On the weekend I bought a hole saw to do a few odd jobs & i was hoping to be able to use it when I start playing with tubes.......
One of the jobs I had was to drill a hole in the wifes XJ bumper to mount the towbar wiring.....it barely marked the surface before the teeth were only a memory - and there was only a circular scratch.......

So what's a god holesaw that could be use to also notch tube etc? where to source one would be good too ta....

yeah id like to find a decent tube notcher also but cant find anyone selling em....

Hey wooders, was it a metal hole saw or a woodwork hole saw? Sounds like you either got a shit metal one, or were using a woodwork tool.

Tanka - was SUPPOSED to be a metal hole saw - but I think they must have been talking lead of something, because it turned to butter on the wifes stock tinfoil bumper.....Mind you at least I got a full refund when I dumped it back on the Bunning service desk

Yup, there are a few cheap kits gettin around but with this sort of thing you definately get what you pay for. I'd be heading to an industrial tool joint for a decent metal one ... they aint' cheap though ... :roll:

you need to go to an engineering shop and buy a proper one, not a bunnings one

the good ones and made from about 2mm wall steel not tin foil like the cheep bunnings one

somewhere like trade tools or a local nut and bolt should be able to help you out

Post by **Area54** » Tue Dec 16, 2003 3:41 pm

Like Bubs said, the wall thickness of the saw is paramount. Also you will get a lot more life out of any cutting type of tool if you use a coolant/lubricant of some sort. There are dedicated lubes to use, you can use kero as a mild lube, its a good volatile coolant though. Compressed CO2 is excellent on plastics.

Spending dollars on quality tools is an investment in your hobby (wife never believes me - "you spent $89.00 on that piece of steel?")

i got a 70mm high speed hole saw from bunnings the other week. I drilled about 1o holes in 5mm mild steel when i was doing my spring over . You have to buy the blue ones cant remember the brand in was almost 5o bucks . I drilled it all and only lost one tooth probly cause i was going too hard. You need cutting fluid, i wouldnt even bother with those crapy multi packs where you get 5 or 6 sizes for about twenty bucks. spen the money and it will last for ages

Try mitchells engineering supplies wooders, in the industrial area of hornsby. Don't have a number for them but i'm sure they're in the book.

Wooders Butler and smith opposite us sell the holesaws that last. You'll find if you spin it too fast it will wreck the teeht as well.
I baught a cheap notcher from Hare and Forbesfor $120 and it works awsum.

i've got both snap on and bahco ones. both work awsome but are pricey. paid $100 for 2 bahco's.

just go to a tool shop and buy a decent set. any good tool store will have one, total tools or gasweld.

some people say to spray WD40 or similar on it while going!

I use either Sutton or P&N. For some reason, the Sutton cut through the steel tube heaps better than the P&N. Suttton are blue and P&N are black. There is a white brand floating around which appears to be good quality as well.

Post by **V8Patrol** » Tue Dec 16, 2003 9:25 pm

Sutton hole saws....only way to go , my 2 1/2 " has done hundreds of holes and still cuts the way it did on the first day I bought it.

P&N drillbits are better than the sutton drillbits to... I still have my first set of P&N bits and have only broken 2 bits in 18 years !!!

Post by **Lukey** » Tue Dec 16, 2003 9:58 pm

Listen guys if your cuttimg into your pride and joy or just a shitter invest
in a decent one , not a cheap and nasty from clints crazy bargains, which
will just f**k the job up. P/N are good so are Bacho, but get the proper arbor as well. If you want perfect holes spend the money. I have carbide
tipped ones and they've lasted four years mainly cutting stainless steel
which is hard shit to cut (the carbide tip ones were only bought because I was sick of burning out hole saws every five cuts or so) but remember to
use a cutting oil or fluid as this prolongs the life of the hole saw.

Probably should also be said that a slow speed should be used. Don't know about the difference between P&N and Sutton but my Sutton hole saws work better than the P&N but V8Patrol says his P&N twist bits are the shiat but I've replaced at least half of my P&N drill bit set - maybe I'm just clumsy :roll:

Post by **MUSS** » Wed Dec 17, 2003 12:28 am

id stick with the sutton metal hole saw dude as ive usede the sutton hole saws before and they are resonably priced and usually every good hardware store shood stock em :armsup:

BEEBEE is right... slow speed.... a cordless drill set on slow will do the trick..... so dont use a air drill :roll:

(i did that once) plus buy abit of cutting compound solution that you can dilute with water and pour it into a squirty bottle makes life a whole lot easier

Post by **Wooders** » Wed Dec 17, 2003 9:19 am

I was using wd40 to lube the cutting & I have a big old drill that has a fixed low speed of 500rpm - it's great for redular drilling, but yeah I bought the shitty 6pack for $20 - I shoulda known better :oops:

But I was thinking "it's only 1 hole".......

B&S - Cool I've goten a few things from them before...

Hey all
If you going to be doing a fair bit of notching the only way to go is
with a proper notcher . As sam said previously have a look at the notchers
at hare and forbes .Can notch from 20-65 mm. kram

hare and forbes are found here:

Does it self centre the tube?

thanks for that...so its sort of a fancy vice to hold the pipe while you cut the pipe with a holesaw.
