Re: Best hole saw for notcher ?

I use snap on/blue point and usually get at least 1 cage. I tried a Craftsman and only got about a dozen or so notches. I keep it very well oiled and use very low speed.

It Ain't My Fault

Re: Best hole saw for notcher ?

Ditto.  One cage one bit +/- . 

I have been changing my thoughts on using oil on the notches.  I seem to change bits every cage and the bits are just 12-13 dollars, the oil and mess vs the cost,  make me less likely to want to preserve the bit to say 1.5 cages...

Re: Best hole saw for notcher ?

When I can save up for it, I think I'm going to get a shear notcher, I hear they give better results than a hole saw, and faster.

Re: Best hole saw for notcher ?

We used a shear at my uncles fab shop.  Pretty sexy, 2 second notches...

Re: Best hole saw for notcher ?

If you dont have/want to buy the shear notcher, the best thing I've ever used for hole sawing is the Rotabroach by Hougen. I spoke to the manufacturer a few years back and for these tools the key is applying plenty of cutting pressure and lube. Press lightly and the tool tips wear out fast due to localized heating. press firmly and the heat leaves with the chips. I have a set at work that we have literally been using for years.

Re: Best hole saw for notcher ?

Does anyone make a shear notcher besides Lowbuck?

Re: Best hole saw for notcher ?

I've used a Lowbuck notcher for 20 years on many cages without replacing anything.  They say 6 seconds to fishmouth a tube but it takes me twice that long. They're a bit spendy but worth it in time saved and they will last a lifetime.  Your grandkid's grandkids can use it.  What I would like to have is their hi-buck bender.

Re: Best hole saw for notcher ?

From Lowbuck's website...

"The cutting edges are case hardened to 62 Rockwell, which is 2 points harder than the back of Superman's head, so like him, they are practically indestructible."

Re: Best hole saw for notcher ?

JMR mfg used to make a very durable hole saw specifically for tube notching. They are trying to get them back into production. Right now they are unavailable.       Shear notchers are fast but it gets hard to do high angle or weird offset cuts ( and it seems that most notches for roll cages are high angle and weird).

        We use Wurth and Matco hole saws in our notchers.      The rigidity/quality of your notcher and the way use it have the most effect on hole saw life.     The notchers with shitty bushings and thin shafts  (anything under 1") will EAT hole saws.. The good ones with 1 1/4" shafts, needle or other quality bearings will allow the saws to last longer.

    Movement of the tube is a saw killer, make sure the tube is clamped very well so it cannot rotate or slip.

    Use cutting lube and very slow saw speeds.. Most every drill is too fast, you need to gear them down or use a drill press.

   If we don't make a mistake (loose clamp, etc) we can get 3-5 cages out of a saw...

I've had good success with both Milwaukee and Ridgid brand saws.

Re: Best hole saw for notcher ?

We've noticed that a faster cut seems to help our blades last longer than light slow cuts.  Who knew the heat was in the chips.  I hate the oil for several selfish reasons.

The greatest day ever - when Josh forgot to take the pin out of our notcher and our very strong Milwaukee drill spun around and smacked him in the eye!

Re: Best hole saw for notcher ?

Is that the 7 amp model?  I have one of those and it just begs to break your wrist.  My friends/teammates hate it because it snaps drill bits with ease...

Re: Best hole saw for notcher ?

We use angle templates from  metalgeek.com and make the notch with our grinder just as fast and easy as a holesaw with excellent results. Just type in the tubing size and angle, print out the template, wrap around the pipe and make your notch.

We bought 4 JMR fine-tooth holesaws when we started our Lemons "career", not knowing how long they would last.  We've only built 1 cage so far, but saw #1 is still plenty sharp, and works fantastic.  Cuts fast, and no tendency to grab at all.   We do use cutting oil, and plenty of pressure.

Our notcher is a genuine "ol joint jigger" from ebay for $50 brand new.

Re: Best hole saw for notcher ?

Plasma cutter and a grinder to finish..

Re: Best hole saw for notcher ?

The first Lemons cage I helped build we used a 4 1/2 grinder to notch all the tubes. It was messy but it worked and you only needed to clamp the tube in a vise and go at it.  Not the most precise method but it got the job done. There was a lot of grinding and checking the fit but it was a simple cage with no tricky joints.
Even when you have a notcher you still  have to "fine tune" the fit with a grinder and you should be beveling the tubes anyway for a better weld joint.

Re: Best hole saw for notcher ?

I like chopsaw and angle grinder method. Hole saw will bottom out with any angle and the edge needs to be ground back for welding anyways. The fitment is only as tight as your measuring, the cutting tool is not the weak link (at least in my case).

Re: Best hole saw for notcher ?

Hole saw lenox hands down   I also do not go slow I blast a notch in a few seconds  one hole saw will do an FIA cage.  aka Lemons cage is about 1/2-2/3 the notches.  Ive tried many diffrent ones and lenox for my style works.  I might spray some lube (not real cutting oil) every 3 or so but Im bad its usually pretty dry.
