@RetiredJedi04 Titanium is pretty tough. I recently tried to ben a 7/16" diameter bar of titanium and had no luck. I have a hard time believing the story though.

[BloodPhoenix123]

@SupermaxCNC you'd have trouble bending a 7/16 bar of aluminum man. That's not saying much.

@RetiredJedi04 Titanium is only 6 on the MOHs scale. Titanium Carbide is 9.3 similar to Tungsten Carbide

good video

[TheCurseFilms]

@RetiredJedi04

Titanium Nitride(TiN) is indeed 9.0 on MOH scale and is often used to coat cutting tools, such as drill bits,

Titanium(Ti) itself is 6.0

Tungsten hardness is on MOH scale is 7.5 .

[FilippoGatti1991]

@RetiredJedi04

9.3? Its hardness is 6.

[RetiredJedi04]

@FilippoGatti1991 yep. Just relaying what the jeweler told me. I believe he was referring to titanium carbide.

[FilippoGatti1991]

@RetiredJedi04

Yes, titanium carbide is similar in hardness with corundum (ruby, sapphire,...).

Soomething harder is Tungsten Carbide, but is also more britlle, infact it shatters when pressed with pliers.

I would not buy anything like Tungsten or Titanium Carbide, they are too brittle.

I buy only Titanium or Tungsten metal alloys as jewelery.

Right now I'm wearing a Titanium necklace. It is very strong and lightweight.

[RetiredJedi04]

@FilippoGatti1991 yea it's amazing how light titanium is. I owned a titanium ring and it washed away in the shower. I didn't even know it had slipped off of my finger. I remember hearing a loud noise that freaked me out, but it took about 4 hours to realize my 160 bucks literally went down the drain haha.

[PureWhite91]

you do know the hospital can not cut off these rings if they get bent on ur finger they have to cut off ur finger.... dont belive me look it up

[SupermaxCNC]

@PureWhite91

Not true. A titanium ring can be cut off with ordinary bolt cutters. No worse than having a stainless ring. Heck you could even cut one off with a hack saw. Many of the titanium ring manufacturers dispel this myth.

Now if you had a tungsten ring, that would be a little more difficult.

[scavenom2008]

YOU CAN GRIND A TUNGSTEN RING AS WHEEL OR CRACK IT BY TAPPING IT WITH A HAMMER OR BY PUTTING IT ON A VISE IT IS SO BRITTLE THAT IT CRACKS EASY WORK SMART NOT HARD ; )

[HobbyPicker]

@SupermaxCNC Tungsten is actually easier to get off... the properties of tungsten make it susceptible to shattering when it is squeezed.. Because tungsten is so hard it is brittle. Any attempt to bend it...it shatters. All you need it vise grips.

[skooteroo]

@SupermaxCNC Yes, you are quite right, as several of the comments show, many people who know no better have the mistaken view that Titanium is some super hard super strong wonder metal... when the fact is many Alloyed Steels are harder and stronger. Of course Ti has many other useful properties not the least of which being a Density about 45% lower than Iron.

[darkarura1776]

@SupermaxCNC how would you cut the ring off using the bolt cutter without cutting your fingers off

[SupermaxCNC]

@darkarura1776

A bolt cutter is just a compound leverage wire cutter. Nothing special really. Just snip it off just like cutting off a zip tie with a pair of dikes.

[baccus61]

@SupermaxCNC Tungsten rings can be broken while on your finger. All you need is a pair of vice grip pliers and a bit of time and it can be done without too much trouble. Tungsten may be extremely hard but it is very brittle also which allows it to be broken. Silicone grinding wheel would also do it easily. You just have to keep it cool with constant flushing with water.

[SupermaxCNC]

@baccus61 We are talking about titanium, not tungsten. I think you are talking about silicon carbide, also known as a green stone, I have never seen a silicone grinding wheel. Dont think it would do much.

[baccus61]

@SupermaxCNC Too right. My mistake. I meant a silicone CARBIDE wheel. HA HA. You have to be so precise and careful with what you write here as people will pick the eyes out of anything you get wrong. Keep up the good work.

[SupermaxCNC]

@baccus61 SILICON not silicone. Silicones are polymers like rubber.

[baccus61]

@SupermaxCNC

Aww, (:-) How about Silly Cone, or silly Con the Fruiterer.

Point taken. I'm getting old and memory impaired. I should know this as I am a machinist by trade so I think it's back to the OLD drawing board to brush up on my technology. I do like constructive criticism.

[scavenom2008]

BULLSHIT A GRINDING WHEEL CAN GRIND IT OFF END OF THE PROBLEM DON'T CUT IR GRIND IT ; ) WORK SMART NOT HARD

[SupermaxCNC]

@scavenom2008

Grinding would be a last resort. You could get a real nasty burn trying to grind it off.

[scavenom2008]

well you need some common sense too. That helps!!!!!!!! alot ..You could also say that you could cut your hand off trying to grind it off but that again will be someone stupid doing something he shouldn't be doing and absent of common sense

[jeremy0203]

@PureWhite91

rings can easily be broken apart off a persons finger by using a small vice. there are many videos of it on here, can even be easily done with a tungsten ring. most hospitals carry one for that eaxct reason.

[jaredbaseballfan]

well we'd like to see the end product man lol thats pretty cool tho

[SupermaxCNC]

Added a link to one of the rings I made last year.

[lerhamster]

Diamond?

[SupermaxCNC]

Diamond what? Cutter? No, simple old tungsten carbide. This was an old 5/16" carbide end mill that was reground on my tool grinder.

[SupermaxCNC]

I think i was running 6000 RPM. The cutter was a half round cutter made on my tsugami tool grinder.

[sentinal2000]

what was the cutter made of?

[sentinal2000]

what mm per minute feed rate do you use?

[lagphish]

Neat! what's your spindle speed / end mill diameter?
