Deep Holesaws for notchers......feedback please.

Check these out. We have a guy that is trying to get us to sell these for him. This one is for 2" sched. 40 pipe and it is 5.25" long! They are very thick and beefy.

Notching extreme angles on tube?
Vibration?
Time saver or not?
What do you guys think? Any feedback would be appreciated.

 

Did he demo them for you? Should be able to tell how well they work pretty quickly.

 

Don't know what i would use it for. Have to try it to form much of an opinion.

 

Neat idea. I have run into the need for something like this before.

They better be inexpensive or very rugged as regular saws get torn up pretty quickly if you do this any more than a hobbyist.

 

Ya those would be nice. Is the quality any good? Not made just for wood are they? The short ones usually bottom out at the most inconvient spot.

 

I could see where they would come in handy, We usually had to flip the tube when we were cutting notches for the belly tank frame and cage. It must have a long pilot bit also?
Only thing I would worry about is if it would maybe deflect part way thru the cut being as the bit mount is so far from the cutter.

 

Man I could put those to use! I don't know how many times a stock holesaw bottomed out!?

 

i dont think i have enough clearance on my home made notcher for a longer holesaw, maybe factory ones have more room for longer ones?

 

How big is the arbor? What is the material? Are they someones second line or more chinese ****?

Yes, they could be very useful on steep tube cuts but only if they last more than one cut...


.

 

I also see where this might come in handy, if isnt too pricey i'd get one.
The only thing that concerns me is vibration.
W/ the short ones if the drill aint perfectly straight they start shaking badly in no time,and yes they wear real quick.
Good idea, ill check back and see what becomes of this.

 

Woulda saved us a ton of time and anguish!

 

after talking with my friend that builds cl*** 1 trophey trucks for a living I stopped using whole saws for notching .. he told me a way better way to do it without the use of the saw , it just takes too long .

 

i would love to have a few of those....great for building cages....ONLY if they hold up.....no good if they fail after first cut.....

 

well let the cat out of the bag ...whats the better way?????

 

What I could really use is a holesaw with a higher tooth count.

Something that will work on thinner material, and wont try to grip and rip its own teeth off as soon as you touch the piece youre working on.

( specially if you come in at an angle, like with a tubing notcher...)

 

I had a fast learning curve with holesaw notching. Lots of lube, and copping the tube with the chop saw, at the angle of the notch. As was said, they would have to be reasonable. There are better ways to notch, but holesaw notching is very easy, quick way for the home builder to get going.

My 50+year old leather belt driven drill press is set up with my notcher. I have not used it as a drill press in over 10 years. The belt will slip if something jambs, and it spins REAL slow. I would order 2 each of 1.5 and 1.75 just to give them a try.

If you have used a wholesaw notcher enough to know why you could use a deep holesaw, you have figured out a way around it.

 

I could have used those a few months ago, they are a good idea.
I would like to see a hole saw with 10-12 tpi so it would cut smoother and not chatter so much.

 

No, he sent them to us. Have not used 'em yet. I will keep you guys posted.

 

American made by some dude in Oregon. Just got one today.

 

Saw an add in the back of the new R&C for a Forstner looking metal bit with flutes up the side for metal, I suspect they will make us laugh at traditional holesaws soon.

 

Good idea.Glad they're American-made!

 

I agree with others the need is for a finer toothed hole saw. If they are not bi-metalic then my experiance is they won't last any time at all.

 

Was that the RotaBroach from Blaire Equipment??? If that's what you saw, yeah, I'm ordering some soon!

 

my biggest complaint with holesaws is uncentered arbor holes. Even the good stuff tends to be wobbly

 

send me a couple of them ... I'll let you know how they work

I have been want to build a notcher that uses the Roto Broach mentioned but you are talking big bucks for 1 5/8" Roto Broach.

 

Using hole saws to notch tubes takes forever!!! even in a heavy duty mill, its a long, babysitting process! The best way i have seen to notch tubes is with an abrasive notcher, such as this. my buddy has something like this. http://www.youtube.com/watch?v=qVFhgS0y7CE

 

Maye we should send a couple out to some "notchaholics" for some real world testing......Hmmmmm

 

Yeah, thats the one!

 

Even with the "better" starrett hole saws i use an 1/8th inch under sized one due to the wobble. inch and a half hole saw makes the perfect 1 5/8th hole in plate. i wonder how true these are and how well they hold up. i do some pretty severe angles some times and end up hand notching them

 

if You're sending out samples, I'm Your huckleberry.

what would be a HUGE benifit would also be one with a bit thicker wall.

on 1 3/4 inch pipe, .180 wall, I have to reach in and break the center of the tube out with a screwdriver halfway through the cut. every part of it is hot and sharp.

suffice to say it ****s. it's a good way to bleed and burn at the same time.
