Tool Head Milling Service

*UPDATE – 12 SEP 14:  We have transitioned our spacers from PVC to 7075 Aluminum.  While the PVC spacers served their purpose well, we feel our customers deserve better!  We have a couple of the PVC ones left, so we’ve left the option for them below.   

If you are looking to do conversions such as 300 BLK or 277 Wolverine, or are processing shorter cartridges such as the 7.62×39 on your Dillon Super 1050 press, using the Dillon RT1200 / 1500, a milled tool head is a necessity due to the short overall cartridge length of the 300 BLK cartridge.

This tool head milling service requires you to ship us your 1050’s tool head.  We mill 0.50″ of material from station 6 as shown in the photos.  This is a PERMANENT modification to your 1050’s tool head.  The threads for stations 5 and 7 will be partially milled as shown in the photos, however, will not affect the use of those stations when the trimmer is not present.  Once complete, you will be able to install your choice of a 300 BLK trim die, along with Dillon’s exhaust chip manifold. Our milling is done to allow a near perfect, snug fit of the exhaust chip manifold, without compromising the integrity of center through hole of the toolhead.

We also provide an option for a modified tool head washer, and/or PVC spacer.  Modification of your current tool head washer is required for proper chip exhaust manifold clearance.  The PVC spacer is designed to be placed underneath the chip exhaust manifold, to allow a proper fit, when trimming non-300 BLK cartridges.   This will be particularly important if you do not have more than one tool head for your 1050.  Without this spacer, the manifold does not seat well with the trim die / trimmer.  The spacer will fit around most major manufacturer brand lock rings.  If you require either of these items, please check the appropriate boxes above.
