HTS DRILLING at 900 rpm is UNREAL (you need to see this)

i think they accidentally sold you a tunnel boring machine. unbelievable, liked and subscribed

Most anyone that has ever done any machining realizes that setups usually take a lot longer than the actual job.

Its great to see Australian manufacturing and like the presentation.

I like your humble approach to what you show in your videos. Hopefully, this will keep the negative element that is common on social media to a minimum. The vibration you noticed with the Drill is fairly common especially with this amount of tool engagement. It's like you mentioned. It's a Roughing tool much like a U Drill. I wouldn't be too concerned about the vibration, just as long as you don't start picking up any chatter, which will start eating through Inserts almost as quickly as you went through this material 👍

That's pretty nuts. That thing is a monster

About 50 years ago I worked for a company making shock absorbers for the US space industry, we used an Oerlikon system that had 2 tubes, the coolant came up between the tubes and the swarf was carried down the central tube, we had a huge coolant tank linked to car radiators to keep the coolant cool, the finish in the bored tube was like it had been honed.

Chatter is usually from a harmonic in the material. Try a 100-120 RPM change each direction to see which gives the better result. Some insert tooling hates to be run conservatively, others protest being run hard. Keep the feed rate the same for that test. If there is zero change, keep the RPM and slightly vary the feed rate +/- 5%. One of these will generally give a result leading to a good finish and less tool wear.

I imagine that tool was an investment, but it works.

The tool you have is perfect for the low flow coolant volume and pressure your machine has. The large chips only have to evacuate past the head, and will not get stuck in the smaller diameter past the head I have read the comments, and many suggest guide pads, but this would require an expensive upgrade to a large powerful coolant system and possibly an STS drilling setup, both of which are way more expensive than the option you chose.. I spent half my career manufacturing deep hole drills, and the second half designing them. This was good stuff, and I really believe you have the best tool for the application and restraints you face. And no, I didn't work for Kennametal, so it's not a sales pitch.

Looks very good. There is a Youtube channel you might be interested in called David Wilks. He seemed to stop posting video's now but they are still there. He showed the most amazing trepanning operations I would have never believed possible in some very difficult materials using home made tools on old conventional lathes. If you haven't seen them it's worth viewing.

Always nice to see someone working outside of the box. I have some customers that could use this technique to help their process. Cheers!

Great video thanks for posting

That's unbelievable Matt. Very impressive, thanks for sharing. Good job.👍👍

WOW! Super work.

People like you and videos like these are relevant, interesting and definitely educational. A sad thing has occurred since your company started 60 years ago. A lot of our world has gotten incredibly dumber. Just routine no specials. No challenges. First video of yours I was hooked. Out side the box, uniquely modified or shop created tools. No blah blah blah bland stuff. Exciting and adventurous to achieve bigger, better faster, largest, first of, you get it. That intrigues me and drew me right in. You have a pleasant and very peaceful demeanor, you are incredibly humble and honest and are a humble learner wanting to improve your craft, make customers and your own life easier. These are traits that are so profoundly scarce today. Where others accept "dumb down" you refuse to live a blah blah ho hum life. You push the limits and go for excellence in the process as well as the product, That is the key my friend that made the industrial revolution! Look at some of the old lathes and machines from the 30's and 40's. Your quest for excellence reminds me of those old machines I worked on 40+ years ago. Computers are great for what they are for but creativity like yours comes out of that computer between your ears. That is in truth where innovation really begins. Stay at that you will stand out in your profession if you keep steady dong so! I know I am bubbling over here but this channel, you, your work ethic and your quest for excellence has got me fired up. Keep it coming I am now subscribed and will be a regular!!!

Yes Sir that was truly Awsome !!!!

These HTS KENNAMETAL TOOL need‘s a REAL STRONG machine with a rock solid tool post. If it is not stabil, the drilling resistance increases enormously and you destroy the inserts. I remember , 25 years ago, the old ŠKODA W200 , SK 60 with a 180mm Walter HTS … nice to hear how the heavy chips are falling … but the remaining piece was really dangerous!!! A bit like a boomerang that never comes back…👍👍👍😎 Cheers from other side of the planet!

if vibration and squealing is present the normal rule is to slow the RPM down.This has worked for me using a 25mm WC series carbide-tipped U drill into 4140. Thanks for the video, impressive drill bit.

Used to run the big U drill that you show at the end, daily on 42-48 Rockwell stock! Made many chips with them drills. Done most of it on an old WWII turret lathe, some on a Mori Seiki SL-65.

Iam really impressed. I never used one of these. The surface is way better than i had expected.
