I was watching a rerun of the bottom drawer bugy and have a question.. at

A what speed should I run a drill press with a Milwakee bi metal hole saw ( HF tube notcher )
1.5" cutting 1.5"x.188 wall tube..The tube shark things looks relatively fast ??

Anyone??

BTW WHERE DOES ONE GET THE SIZE DOM THEY WERE USING FOR 3 BUCKS A FOOT ....:thumbdn: yea right

Anyone?
 
I didn't see the show but, I have found that running the Bi-Metal hole saws and high speed seems to burn out quicker and generates a ton off heat.
I run my at medium speed (not sure what exact rpm) and well lubed and always get a clean cut.

Hope this helps.
 
Ian is on Pirate4x4 his screen name is "Ian from Xtreme", you can message him about the pricing. Larger drill bits should be run at lower speeds because they have to remove more material than smaller bits.
From this chart it looks like you should run less than 350 rpm, around 200rpm would probably be best.

I used the HF tubeing notcher and a hand drill when I did my cage. You want to run them pritty slow or you break teeth and/or make a crappy cut. Also use lots, and I mean LOTS of cutting oil. The hole saws last a long time if you take it easy. It isn't nearly as quick as an expesive unit but it is cheap and if you make good measurements the fitup can be very good.
 
I have done a lot of tube and pipe notching and from my experiance I have not really found high or low speed to make a difference in the life of the hole saw. I have found that the Lenox brand hole saws last longer than any others I have used. Ridged brand plain sucks with Dewalt brand not too far behind, Milwaukee brand hole saws were not too bad but still didnt last as long as the Lenox brand. Something to help make cutting easier other than oil in the life of the hole saw is get an air gun running from your air compressor and shoot air right at the hole saw. The air helps cool as well as removed the metal chips.

I was interpolating (relating the other columns to the steel column for all other rows) the data to get 350rpm. It doesn't matter if the chart was published in wood magazine, they still drill holes in all sorts of stuff (yes, even metal) and a drill press is a drill press. The chart is on a bunch of other websites too.


The link for the 200 rpm suggestion was to a plumbing site where they are talking about drilling into 3/16" steel with a 1-1/4" bi-metal hole-saw.

I got my notcher from ProTools. I have to agree on using the Lenox brand hole saws, they definitely last longer in my experience. As far as speed, I use a regular hand drill and I run it slow. Most everyone I see drilling anything (i.e. with a drill bit, or hole saw), runs the drill way too fast. The key is steady pressure and low speed. If you use a high speed, you will heat up the metal and work harden it and burn up the bit, hole saw. I don't use lubricant of any kind and I just finished an entire cage from the rear bumper to the front, and I only went through two hole saws and the second one is still fine.
When drilling through thick material with my drill press, I use water in a squirt bottle to "cool" the material (I was given this advice from a machinist). It evaporates and keeps the material and bit cool but doesn't get oil all over everything, it has always worked great for me, and my bits last longer.

Not trying to preach, just my experience.

I liked the part where they built that ford ranger, and then tested it and all the suspension basically crumbled under it...

...They put on a great comedy show.

well i did pm ian to see what he says


as far as the breakdown they claim that the used a grade 5 bolt instead of grade 8 and that why it failed...



so what size would have bee appropriate fir a buggy yet cost $3 a foot
 
The best tip to keep lube on a hole saw (if you are cutting down, not up) is to stuff a rag inside the saw itself and soak it in cutting oil. The oil will constantly drip out of the rag and onto the workpiece.

I would go 200-300 rpm and feed it as hard as you can go.

HTH
 
So let me get this straight they built something that broke under hard use on it's first shake down trail run and that makes them worthy of being hated on?
:bs:

How many of you haven't broken something you built? If you say you've never broken your own work then you're either lying. Or the hardest thing you've crawled is a mall parking lot :)

Now Trucks on the other hand... their's a show worthy of hating on... Nothing but bolt ons, product placement start to finish and the hosts are horrible all three of them. And it used to be their best show with that Geeky shop teacher guy who had serious skills.
