Hi oddjob,
                        1D-2D etc is the depth ie 1 times Diameter, 2 times Dia. and so on---Ken

                   I only have standard pitch/depth inserts, but willing to loan for postage costs

[ka-ja]

Hi,
     Sizing is on thread size 6mm.1D is 6mm dia and 6mm deep, the depth needs to match depth of the hole because it is difficult to remove excess once the thing is fitted, or if the hole has no bottom and you end up with the insert too deep----Ken

Hi,
     They are making the assumption they are selling to engineering trade I suppose---Ken

[MikeM]

cant find a 10 mm deep coil, can you use two? say 5mm each ?

[ka-ja]

Hi,
     PM me and I will try to help, you need a 6mm helicoil by 1.5 depth if available, but a 6mm standard length should do, as the helicoil is far stronger than the original thread, and it seals under the bolt head, not on the threads---Ken

This is what i was going to order

m6 x1.0 x8mm ?

[hairygit]

No, it's not a good idea to try and use 2! I have seen 1.5 dia ones which are 9mm long for M6, I may even have some buried at the back of my workshop, I will check for you tomorrow

Just found the e bay item you want, number 111273402176  he does them in packs of 10, less than £3 including post, they are 1.5xD which is 9mm long, just in case I can't find any

Hairy, there would be no point sending Mike a helicoil without the tap and insert tool. Even if he bought a helicoil kit, it doesn't come with a tap wrench.

[hairygit]

Hi Trigger, I had assumed from Mike's last post that he had ordered a kit but couldn't get a kit with Dx1.5 coils:))

thanks all

just bought the 8mm kit , no big deal I will order the 9mm coils as well,  great fun this drilling lark 

[Trigger]

Sorry, Hairy. I am getting lost here Mike. Why have you ordered a 8mm helicoil kit when the oil drain bolt is 6mmx10mm? When you say 8mm do you mean the length??? 

[Bryanj]

Get a cheap set of "rats tail" files as if there is any coil left outside after fitting to full depth you use the triangular file to put a notch in the coil wire at the edge of the hole and break off the excess---hope that makes sense asit's a damn site easier to do than explain
