HSS vs carbide inserts

Just get 1/4 inch, bigger is not necessary and takes more time to grind down. You can often find a job lot of used ones on ebay that are vaguely a usable shape to start with. Do not get tempted by a box of a dozen nicely painted toolbits with brazed tips as most will not be used and the rest are made of sawdust.

Lots of double ended 6 in grinders on amazon and ebay but check on receipt that the wheels are not chipped and ti doesn't vibrate like a road compactor due to out of balance wheels.

Warners make the ones that LMS do

Don't forget the joys of tangential tooling, nirvana for HSS freaks.

I would say it helps to have already been introduced to grinding in a working environment. You can't beat that kind of introduction and it would be a little unfair on a total stranger to wheels to expect them to pick up a book and get it immediately, tangential tooling would be a good start in this case but for many of us it's second nature to just quickly create proper geometry for cutting quite quickly and therefore unnecessary to spend inordinate sums on tangential holders.

For what it's worth (hate acronyms!!) I've been using the A R Warner HSS inserts for about 10 years and they are excellent. Resharpening them just requires a whiz on a diamond plate, 10 second tops. Just as long as you haven't knocked lumps out of them!!

Hi Neil,

Can you please enlighten me - what are the joys of tangential tooling? A worthy subject to cover in ME Workshop?

Regards,Chas

Chas,

You can do worse than watch this video from Eccentric Engineering... **LINK**

Other toolholders are available.

Jon

Oh yes, I wouldn't be without mine.

I take it inconsistencies are your bugbear? They are part of nature after all.

Re Arthur Warner's HSS inserts.

I would like to try these items, and from reading these forums (forii?) I rather think that so would other people, but I have been put off by the apparent complexities of ordering them, and the costs entailed therein. It seems to me then, that what we need is some enterprising company - are you listening Ketan? - to look into it and perhaps gauge interest by asking for possible orders before considering a bulk order! For me, the equivalent of CCMT060202 (CCMW-2-1.5-0.5?) might be the ones.

Just a suggestion.

I wonder how much future there is in HSS inserts now that you can buy sharp carbide?

What's complex about ordering them, easy from LMS who have a much cheaper P&P than Warners and that will hopefully be off set if it gets through customs under the limit where as Ketan would have to charge VAT and maybe even a tiny bit of profit.

Those threading inserts from Warners look very interesting.

Do any tangential toolholder fans use theirs for threading? It's something I've never tried but would like tp give a go if I can get the geometry right.

My instinct is that the nose angle must be quite a bit over 55 or 60 degress so that the cut ends up on-angle but I'd be really interested in other's experience.

(I need to get my head in-gear to work out the combination of 60 degree across the corners grinding angle and 12 degree back rakes in each direction)

Jon

I thought they came with instructions on how to grind for 55 and 60 deg screwcutting.

Quite right Jason they do. I have to say though that I've never used the tangential tool for screw cutting - but there again I don't screwcut many threads! Most of my threads can be achieved by means of taps & dies.

Norman

Well they do if you buy the Eccentric Engineering version, I made my own and they didn't come with instructions

I've been taking all your advice on board , gonna have a look for some hss tooling . Was on another forum this last few days ,been very interesting. I've been donated a motor and some hss tooling from a member unbelievable generosity on his behalf ,infact we were just talking on the phone tonight . This kind of generosity put a little bit of faith in mankind as they say . 😀

Well, that's me sorted out!!

cheers, I think

Bill

Just teasing, Bill
