| a question about dies |

| Houtenkrullen:
P.s. There should be at least some taper on the side of the die with the brand an size markings if yours are like mine. Looking at your pictures there seems to be some?? |

Mike. To me...... Those look like split dies. Without the splits. :scratch: Guess the manufacturers add a split, or not. Depending on customer preference...... :thumbup: David D |

Thank you Peter, :thumbup: I was beginning to think that maybe reading about these dies on the continent had just been a dream :palm:,It's nice to know that it's true and split dies are'nt readily available...but why it's like that,,I have no idea...The photos don't really show the taper too well, but it is quiet deep,,As good, if not better than the old BA dies I have but then maybe their worn down... David,, that's what I thought at first but now i'm more confused than ever albeit with a lot more possibilities ... :scratch:.. I think it's time for some experiment's... :dremel: :loco:... ... thanks again Modder think tank... ...mike... :clap: |

Its the other way round for most rarely do we ever see a rethreading die. Do have one decent Goliath M8 course split die brand new pre 94 boxed and does have the hex outer for spanner work. The first set of taps and dies came from local motor factors, cheap and nasty carbon most broke with no effort but were all rethreading dies. Think what this boils down to is where you do your shopping. If shop at car/diy place expect rethreading die, if shop at a reputable engineering supplies expect a proper split die where rethreading dies could be supplied to order. Even ebay worldwide its harder to find rethreading dies, split are the norm. As regards the two indents Normans 100% that's how to adjust the size the die cuts and to stop die slipping, no other purpose. Between the two indents if you like theres a centre which will expand the die up when driven in. Self explanatory |

Highly interesting thread. Now, before I start; I've been working with toolsales ever since I left the army, before that i was trained as a gunsmith (which I also worked as in the Norwegian army). I have exclusively worked with pro industry customers now for 15 years for the largest tool distributor in Norway with some of the largest European tool brands. That aside, i think there's some pretty basic differences between continental Europe and GB and the USA. I have never seen a split die, but vaguely remember them beeing briefly discussed during my years in school. As others have mentioned, here and in other places continental europe the die in question would be a standard threading die. MOST of those have a lead in taper on the side with the manufacturer markings (But can be ordered with minimum or no taper for special applications). One example of such a die which produce a finished thread may be found at the top (and onwards) here: http://www.dormertools.com/en-gb/products/pages/ProductSearch.aspx?primarycategoryid=dies Now, a cleanup die would in MOST cases be hex like this: http://uk.farnell.com/dormer/f302m16/hexagon-die-nut-hss-16-x-2mm-metric/dp/1477492 All the holes, and also the portion which you wanted to cut Myfordlad, on a die has a corresponding screw on the dieholder which locks the die into the holder. One example of such a dieholder is here: http://shop.stianmotorsport.com/produkt/10421786/gjengebakke-38x14mm-m12-m14 This regular type of die cuts a fully finished threadform, but you cannot but trust the manufacturer when it comes to finished sizes. I've been looking for a set of split Metric dies to be able to adjust the fit a little better, but for regular use those dies work fine if you choose reputable manufacturers. Now there's also one manufacturer still producing square dies and relevant tooling, which is slightly different but most of the same applies. Please note i have used random pic's and links off of the internet to avoid someone taking this for something it aint. I have no connection to any of the products, manufacturers or otherwise which i've linked to. Hope this helps some. |
