Works great
My plastic gears broke when I first used my end mill. I ordered this kit and it was easy to install. It is way quieter and worked better than the gears. Not sure why one review said it wobbled as I had no problems.

Amazing conversion kit...For the Sieg X2D mini mill sold under many different names
Fit and finish is great. Paid $159.95 plus tax and shipping. Few things in life are a no brainer - this is one of them. Buying this accessory is essential for running the Sieg X2D mini mill which is sold under many different names. The pulleys and plates appear to be CNC'd. Think of the cost of buying the raw materials, parts, the machine time etc and the time to figure out the dimensions etc to make this kit ; the $159 is a true bargain. This kit expands upon the available speeds of the mill and reduces sound and eliminates the need to replace the original weak and easy to break plastic speed gears. Arrived double packed box within a box. The seller Little Machine Shop is great! LMS included printed paper instructions too. Highly recommend Little Machine Shop! ... show more

It works and was easy to install
Well made parts, great color instructions, and all the hardware you need. My only complaint is the pulley needed de-burred. It’s very sharp, and could cut you easily.

Best minimill upgrade
This is high quality. Precise fit and easy install. Highly recommend this upgrade from the start because you will eventually have to do it anyway, due to the plastic gears that will strip out with use.

An absolute necessity. The mill is a joy to be close to. Installation is straight forward. My only issue on my machine , CX605 from Busy Bee Tools , was the metal cover over the fine feed shaft. The cover interfered with the spindle lock and prevented the base plate from seating squarely on the head. Not an issue because a new cover is a breeze to fabricate. I am very pleased with the kit. It was complete and I found the finish of the parts very good. More than happy. Many thanks LMS. Carl ... show more
