As I now have my Barker lathe set up I am beginning to practice taking some cuts, experimenting with speeds and cut depths

Obviously I have made a few errors during these learning moments and have half broken one of the tools tips, the one one the knife tool

My set of tools are these:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260587858028

I have messaged the seller but he has not responded. I took them along to the Harrogate Show but no one had any to match

They are square, measuring 10.2mm per side, with 0 degree relief and a single groove on the top side. They are secured by a detent mechanism, basically an upturned L which is locked by turing 90 degrees

I have spent ages searching online but just can’t find anywhere in the UK selling these tips

Can anybody help please?

I don’t know whether this will be of use but if you go to the Sandvik UK site they have on line catalogues in pdf format giving details of all of the tips they supply. If you have measurements of your tip pre-damage then it may be possible from this source to identify your tip and get a part number or more importantly a generic type description, tcmt, pcmt, etc. This would at least allow you to source a supply to replace any future breakages.

The Sandvik on line catalogue is broken into sections describing, for want of a better description, tip application i.e turning, grooving etc. I suspect that yours would fall into the grooving/parting off category.

May be worth look if your tool supplier fails to answer.

Cheers

Hello Mr Coates.

I’m writing from Portugal.

Perhaps Your lathe’s cutting tool set is a sub-set or a super-set of my own set which looks very much like Yours.

.You can get some information about (my set) in a catalog from Optimum Machines,

pages 90 and 91 You can download from the following URL:

http://www.optimum-machines.com/fileadmin/Kataloge/Optimum/Catalogue_GB_08.pdf

If You find there what You are looking for, then You can buy it in Excel that distributes the Optimum range of machines. Its URL is:

http://www.excelmachinetools.co.uk

Good luck to You

Hi,

KBC Tools in the good old US of A has a fantastic webpage that lists the dimensions of all their products.

http://www.kbctools.com/usa/main.cfm

Click on the heading on the left ‘Carbide Tooling’, then choose from the menu and it will open a pdf. with all the details.

The ‘Carbide Inserts’ page is what you want, although it didn’t open just now when I tried it. (Page 247)

What you can do is open a previous or a later page and scroll backwards or forwards using the ‘previous page’ or ‘next page’ buttons.

I saved the page that has all the tips dimensions and codes page on my computer so I have a ready check list. Any of the pages can be saved too.

Hope that this is of help.

Andy

I was interested in the chart mentioned in the last post but when I clicked on carbide inserts I got a file not found message.

This chart may help you identify you insert. It is the first four letters that are the key to searching further. e.g CCMT is a poular type for many holders sold in the UK but yours sounds like something completey different – i.e S for square N for no relief M (tolerance) N for no hole

Best of luck and hope that helps

Well the seller did get in touch and although he sells the tips, he doesn’t have any in stock, so he directed me to the Warco site. There is a set of replacement tips but as the tools look different to mine I’ve asked him to confirm they are the right ones. Needless to say I’m still waiting for a reply to that question.

Thanks Dias. The Optimum catalogue has something very close to my tips, I’ve just got to be sure the centre hole is the right size.

Hopefully now I am not far away from getting some tips

Thanks to all for the help and advice

Dias – thanks for the link to Excel Machine Tools. They want £33 + VAT + P&P and I only want the square inserts, not a full set so Gulp !

So far I can work out that mine are SN*M (Square, 0 relief angle, single groove with straight through hole) but I’m getting stuck converting the imperial Size and Thickness to metric from my measurements

I measure 10mm sides, 3,6mm thick and 4mm hole

Is this 303035 ?

Sorry all

Should clarify that what I mean is I am having difficulty relating my metric measurements taken off the carbide tool tip to the imperial references in the standard

Thanks for anyone who can help me. Once I’ve got the code I can try and find a supplier just for the square tool tips only

Go to http://www.cutweltools.co.uk page D14 for SN** series, but from your rough dimension they look like SC** on page D13

Hi John,

As the inserts have zero clearance are they double sided or just single sided for neagtive rake machining?

Any chance of a closeup picture of the insert?

I have the Sandvik Technical Data chart in front of me but without having the insert to hand makes it a tad tricky.

Guessing at;

S               Square inset

N               Zero clearance angle

M or U    Tolerance of inscribed circle (ie don’t worry about it)

M               Guessing at single sided insert with positive rake held with pin not screw

09              Closest to given measurement at 9.525mm (next is 12 at 12.7mm)

T3              Closest again, T3=3.97mm, 03= 3.18mm

XXXX          = Nose radius ie 0.2,0.4,0.8 etc

So could be; SNMM09T304 (for 0.4mm radius) etc

In tha past I have phoned Peter at Greenwood Tools who has been able to supply me with just about any sort of insert in any sort of grade and has been more than helpfull (usual disclaimer)

I seem to remember that you could send Greenwood an insert and they’d be able to identify it for you and suggest an alternative.

Hope I haven’t confused things too much

Ebay is a good source for carbide tips, I have picked up quite a few bargains in the past and often make a suitable holder for the tips. If you are familiar with the nomenclature you can tell the size,shape and tip radius before you place a bid.

Hi folks

Here is the tool tip – a good one taken off one of the other tools. I have checked my measurements again and found that the top of the square measures 10.05mm per side and the bottom 10.00mm per side so there is a slight rake (clearance). On the underside there is a slight recess (counterbore) around the hole but it is very shallow and I can’t measure it

Over to you

I have checked a number of manufacturer’s list for these sizes and do not find any matches. Either the measured size is wrong, but you have no doubt been careful or else you have been sold some cheap non standard item.If your supplier cannot/will not help then you may have to start again using a reputable source such as Greenwood as mentioned above.

KWIL – you may be correct about the cheap non-standard item

When I put the codes of the three knife tools into Google (PSSNR1215H09, PSBNR1215H09 AND PWGNR1215H06) I get results for several Chinese manufacturers offering bulk sales (1000+ units) of the nine piece set I bought

Going to their websites does provide product numbers for the carbide inserts, namely 41005V, but no UK stockists

Seems like my only choice is to replace these tools with better ones where I know I can get replacement tips as well

Bugger! More expense when I could be buying metal

Regretfully you usually end up getting what you paid for, in this case not a lot. Stick to ISO inserts and buy the toolholders to match.

I would whole heartedly endorse the statement by KWIL. I was going to buy a set of insert lathe tools from a well-known ME supplier. Having pushed the sales person they eventually admitted that the inserts were non-standard, so I didn’t buy.

On another note regarding insert tooling I have found that the Glanze boring bars (Indian made) from RDG are of reasonable quality, but the supplied inserts are hopeless. Fortunately they take standard ISO inserts, which I get from either Greenwood or industrial suppliers.

Andrew

Hi John

The following url :-

http://www.chinatungsten.com/Tungsten-Carbide/Mechanically-Clamped-Inserts/Type-4V.html

will take you to a page of a cataolgue where you will find details of the inserts that you are after. The bad news is that it’s a chinese company but the catalogue is in english (and just about any other language you want). There are contact details for the company on the website that the page will access so you could always try e-mailing them to see if they have a european outlet, or even if they can supply direct. Who knows you mightfind that they can supply at an economic price. I bought a optical tachometer from Hong Kong and it came for under £10 including the shipping – wasn’t even worth costing the bits out to build one!

Hi,

I have just joined and I saw this post and thought I could help you.

I have the same set only 16mm and a few other guys I know have the same set. We have looked a every catalog for the tips and there is nothing matching to suit these.

They are made to suit these sets. The 12mm fit the 16mm ones and I buy mine from here in Australia from this guy on ebay.

http://cgi.ebay.com.au/9PCE-REPLACEMENT-INDEXABLE-CARBIDE-TIP-12MM-16MM-/350385988760?pt=LH_DefaultDomain_15

They should work out around 13-14 pound a set thats only about £1.40 each.

With the exchange rate they should work out a lot cheaper even with postage as they are only small. You could ask him how many you could fit in the package for the same amount of postage.

These are the sets he sells

http://cgi.ebay.com.au/12MM-1-2-9PCE-INDEXABLE-TIP-METAL-LATHE-TOOL-SET-/270619088451?pt=LH_DefaultDomain_15

http://cgi.ebay.com.au/16MM-5-8-9PCE-INDEXABLE-TIP-METAL-LATHE-TOOL-SET-/270624941187?pt=LH_DefaultDomain_15

There is a place over here that sells them single but it works out expensive. I think they are about $6-$7 Aus each.

It’s a change seeing things over here cheaper than over there.
