The Diamond Tool Holder - Features and Tips

[@trevorreeves5041]

Had mine for near 20 years....must have been one of your first customers....its my 'go to' tool....works brilliantly.... Thanks Gary

[@eccentricengineer]

Thanks for your comments Trevor. I often get customers coming up to me at shows and tell me they bought a tool 10-20 years ago and it's still their main go to turning tool. Treated respectfully they will easily last a lifetime.

[@johncorden5610]

Excellent video! I have had these holders for some time but still learned some new techniques. Many thanks, John

[@eccentricengineer]

Thanks John. Yes there are a number of techniques such as turning the tool bit 90 degrees to give a shear cut that many users would not be aware of.

[@topari01]

Excellent presentation. Thanks for posting.

[@whiteblock8]

good to see you posting another video. good tools

[@eccentricengineer]

Thanks for your comments whiteblock. I'm hoping to do some more videos when time allows.

[@smartypants5036]

Nice tool. Must be great for the hobbyist. I want one for sure now that I have seen this demo. Such fine finish has been very hard for me to achieve on my small lathe.

[@EitriBrokkr]

This thing is amazing. Its now my go-to turning tool. Mind you, I've got a drawer with $1000's of dollars of carbide tooling. My only complaint is I didn't buy it 10 years ago.

[@eccentricengineer]

Thanks, glad to hear you are happy with it.

[@EitriBrokkr]

@@eccentricengineer as you showed it has no problems with metals. But the inherent geometry really shines in plastics. There is nothing better.

[@samkaplitz9036]

Glad to hear this positive comment!

[@TomKirkman1]

Best cutting tool I've ever used. Are these still available? I have a small mini lathe I'd like to source a set for.

[@eccentricengineer]

Yes they are 🙂👍 Just check out the website for sizes.

[@victorrussell6284]

Excellent tool, I’ve had mine for several years.

[@stejac51]

.. Excellent info Gary ..

[@ericpope7835]

I recently bought the diamond tool holder and I love it but now its time to sharpen some bits. It looks like you are using a 6" grinder, is your tool rest (table) at the centerline?

[@crjpetersutube]

Anyone know what the wheel is on the Ryobi Grinder shown at 9:46 and several other places? Thanks

[@4GibMe]

Diamond.

[@SergeiPetrov]

I was always surprised by one moment with this holder. Why does HSS blank sharpen not at every corner? Indeed, in this case, it is enough to turn the cutter when it becomes dull and work? Trips to the grinding machine are 4 times less frequent. And the cutter consumption is 4 times slower?

[@peterroach9045]

Because the "end" grind creates the top clearance/rake. Even if you ground with zero rake, the tilt off the tool bit end has a compound slope, (slight concave because of wheel diameter). You could use all four corner IF you hollow out the end and ground each corner separately, so you would have a castellated end. Easier just to buy and use more pieces. ( HSS bar comes in 4" lengths so just chop a few bits.)

[@johnkinnane547]

G’day I use these a lot one thing that I meant to ask you is do you make a grinding table for an 8” grinder? Kind regards John Tasmania

[@PerryRT]

Just got a set for Christmas and am enjoying it so far! One question, though: any suggestions for chip-breaking in aluminium?

[@eccentricengineer]

Glad to hear you are happy with the tools Richard. I usually use 2011 free machining grade whenever possible as it comes off in small chips rather than the long strings of some other grades. If I need to use 6061 or 6262 Ally I put a chip breaker on the top of the tool bit with the corner of the grinding wheel. I'll have to do a short video on how to add a chip breaker when I get a chance as it's a bit tricky to explain in a comment reply.

[@robert5]

Richard, check this out, it will explain everything you need to know on grinding tool bits concerning chip breaking and all other needed aspects: kzbin.info/www/bejne/lZCkY6uqgatjd7c

[@ronkellis769]

Hi Gary. Been having a bit of trouble of late burning up HHS tool tips and I'm sure it's me. I need to verify my tool rest angle, but one question is how long do you generally extend the tool in the grinding jig? Second question I thought I'd ask here so if it's a dumb question no one else will need to ask. I saw the comment below on the tool holder at 90 degrees, and that's what I've been doing. I assume where I've noted a different angle it's an older model tool holder. Normally I use a 1X2X3 block off the chuck face to set a 90 tool holder degree but the tool angle to the work looks really shallow. Is there a tool to work angle I should watch for? TIA, Ron/Shiseiji1958

[@vl_hantverk]

Hey Ron, did u fix your problem with the burnt tips? Im curious to know, thanks Victor

[@ronkellis769]

@@vl_hantverk Yes. It was probably my feed rate, but also using a tool with a radius on the nose took care of the problem. I now grind one end with a radius and leave the other end sharp. If I need an absolutely square cut I will just flip my tool over.

[@nickvee9468]

Do you have a video of grinding a 29-degree angle/profile for acme threads or has anyone easily done so?

[@hoernst2762]

Die Besten!

[@andrewhenderson7422]

Hi, what grade of steel is being turned in the video? Thanks

Where buy

[@bluehornet6752]

Beautiful, and just what I'm looking for. Sent you an email after looking through your website!

[@What-is-thehandle]

Where do you buy this holder?

[@colinwarner7762]

Dear sir I live in UK where can I get these! regards Colin, UK.

[@eccentricengineer]

Hi Colin, if you have a look at the UK distributor page on my website all the details are there including prices in Sterling. www.eccentricengineering.com.au/index.php?option=com_content&view=article&id=17&Itemid=43

[@yak-machining]

Where can i buy one in Germany

[@eccentricengineer]

The Diamond Tool Holders are available online through the website shop or my distributor in the UK. I’ve shipped many orders to Germany before. www.eccentricengineering.com.au 👍

[@yak-machining]

@@eccentricengineer will there be custom fees due to brexit?

[@trevorreeves5041]

BTW: Have you changed the head angle?....my toolpost needs to be off set by 7.5 deg to the left to cut and face without being moved.

[@eccentricengineer]

Hi Trevor, yes the head angle was changed a few years ago so that when the shank/toolpost is at 90 degrees both the left and right hand tools will turn and face a workpiece without having to readjust.

[@duanedickey7043]

Is that the case for the larger 16mm holder as well?
