3293 forum posts 112 photos | I don't know the specific ones but some inserts have part of their identities etched on them in teeny-weeny letters. Might be worth examining one or two with a magnifying glass. |

1186 forum posts 11 photos | There is a useful guide to decoding inserts here: https://www.cutwel.co.uk/blog/learn-the-turning-insert-iso-code.html You need the first seven fields of the code. Given that they are square, with no hole, that reduces the possible codes considerably. Any codes you cannot positively identify, guess at a letter and type the result into Google. If there is no-one supplying inserts with that code, cross that possiblity off the list. Just from observation, the first letter of the code is S. Measure as best you can the second one. In practice, the third one will be M. The next easiest to identify is the fourth field: it will be F, N or R. Fields five and six from measurement. Field seven, try 02, 04 and 08.

7227 forum posts 21 photos | If you can find the code for the inserts, there will be several possible UK sources, as well those to be found on the web. Even the dimensions will help to identify. Arc Euro, J B Cutting Tools, RDG, Chronos immediately spring to mind, plus probably our other usual machine tool importers Howard |

7061 forum posts 719 photos | The insert type doesn't seem to be mentioned on the appropriate Chester product page. That's a red flag and means I'd avoid the cutter like the plague. The inserts are probably not standard and/or not common. So you have to buy them from Chester. Andrew |

4655 forum posts 304 photos | Square they are, but very old design, that will be the reason that Chester no longer list them. I agree that the Cutwel insert identification page is well worth using and once a reasonable code is found, then ebay would be the first place I would look. The rads may vary, and a close comparison between the existing inserts and the seats will give a good idea whether slight variations will fit. Sometimes it is easier to give up on the old tooling and get something up to date and easily available. |

25215 forum posts 3105 photos 1 articles | Chester do list them, they are in the OP's original link. There are several of the hobby suppliers who don't give the codes for the inserts, in many cases it is so people go back to them for inserts rather than sourcing from elsewhere |

4655 forum posts 304 photos | Pity the code is Chester's stock code and nothing like an insert code. So if they are discontinued it will not help. |

Chester do list them, they are in the OP's original link. It's a stock code, not an ISO insert type. Which is why i said the insert type wasn't mentioned. Fine if one wants to order from Chester, useless if one wants to order from elsewhere. Andrew |

1186 forum posts 11 photos | This one, labelled Clarke, looks identical: https://www.clarketooling.co.uk/product/clarke-2-mill-cutter/ clarketooling is one of Chronos' many aliases. https://www.chronos.ltd.uk/product/milling-cutter-2-2/ Clarke stuff is available from Machine Mart. https://www.machinemart.co.uk/p/2in-mill-cutter-2/ (Note clearance price compared to other suppliers full price). Machine Mart's spares email or phone might be a possibility for a lead. |

3988 forum posts 1799 photos | Hi, if you actually go onto Chester Machine Tools web site, you will find they are out of stock of both the MT2 and MT3 complete tools, and the tips are not listed in the option at all It's just the same on their Hobby store site. I got one of them when I bought my Chester Champion milling machine, and I found the tips soon lost their edge. I've found the body of it, but I remember I'd taken off both the tips and the piece that holds them in, and I can't remember where I've put them. I'd got the idea of fitting triangular ones in their place, but it didn't look very feasible, and it's just been sat in my garage for ages. Regards Nick.

72 forum posts | I think they are an iso insert SPKN is the geometry which is an older style of insert so similar to Sandvik SPKN 1204 ED R or L SPKN =geometry 12 = size of the square 04 = thickness this can vary 03, 04, 05 ED = makers designation for the ground facets ( I think) R or L = right or left hand then add the ISO grade of carbide you require eg K20, P40, P20, etc if you cant get the correct thickness you can always shim between the clamp screw and the insert, you can also use any square insert that will fit in the pocket of the cutter including turning inserts which are much cheaper than ground facet milling inserts hope this helps
