![]() 2549 forum posts 235 photos | Do you mean ER25 not EM25? If so you can buy one with a parallel shank that can be fitted into one of your R8 collets. This will allow you to hold a drill or cutter a little lower without extending the quill. You will also have the option of how far out you extend the ER25 collet holder within the limits of the shank length. The risk with doing this is that there may be slightly more runout at the cutting point. It has not caused me any problems. You may find that it help with access for some jobs where a smaller diameter tool holder is useful. Martin |

Make sure that your handles on each end of the x axis are tight as they set the backlash...or in your case the power drive fitting at one end Ah right, many thanks, will have a look

![]() 16 forum posts 38 photos | Echo: SHCS?? I have been the happy owner of the smaller sibling, WM16, for several years with no serious issues. On mine the bellows limit the downward travel of the head. The quill handles can also get in the way and I sometimes need to unscrew one or more of the spokes. Also, the x-axis locking screw handles can foul the front of the y-axis dovetail and bend the screw. Sheer carelessness on my part. I never managed to eliminate all the backlash, but I didn't try too hard. Since fitting a DRO that problem has become somewhat academic. Wish I had fitted a power-feed though. Cheers, Tony. |

I had wondered about the bellow and was set on removing them however they were not completely squashed. I can only assume thst the gas ram, inside the column, is at its max compression. Been trying to thing of a way or sorting but nothing comes to mind so I recon I will just have to work around it Agreed re the DRO, however it would be nice but have played with the screws etc and there is still some ![]() Edited By petro1head on 04/03/2017 11:00:09 Edited By JasonB on 04/03/2017 13:12:34 |

![]() 2947 forum posts 468 photos | I have the ER 25 set which only goes up to 16 mm capacity; go for the ER32, you then have up to 20mm capacity when you want it. |

Yeh thats what I was thinking also the smallest shanked cutter I have, is 6mm and thats for a 2mm cutter, can't me ever needed a 1mm cutter, not for car work So looks like I will have some R8 collets for sale Edited By petro1head on 04/03/2017 15:13:19 |

![]() 16 forum posts 38 photos | I also got the ER25 set and now think that the ER32 would have been better but mainly because I have MT2 on both the mill and the lathe and having the option to hold > 16mm stock would be nice. FWIW I have cutters larger thatn 16mm but with 16mm shanks.

![]() 25215 forum posts 3105 photos 1 articles | Given the size of the mill I would go with ER32 on an R8 shank - one less item to give runout issues. Ball bearing nut. Don't be in a hurry to get rid of the R8 collets they will come in handy when you run low on room under the quill or if you are using the same size ER collet to hold some work as the size of cutter you want to use. |
