"One Perfect Part at a Time"

Shars Preminum ER16 Collet Holder

I just received this R8 to ER16 premium collet holder from Shars Tool Company in St Charles, IL. It is brand new and rated at 0.0001″ runout at the face. What that means is that this collet adapter should be able to run at well over 10,000 RPM without problem.

When you spin that fast and faster, things like balancing the collet nut become necessary. You can see that has been done on this adapter. I will never get close to that rpm on the X3 mill but it is nice to know it is that good.

I have some projects that need machined with small end mills. The manual Taig mill with an ER16 spindle would be perfect. My Taig mill is set up as CNC and although it could be controlled manually, I like to use the X3 with the DRO for manual milling. Higher RPM would be nicer on the X3 for small bits, but I can live with 2000 RPM and slow feeds.

The adapter looks like is was made from stainless steel but it is nickel plated to avoid corrosion from cooling fluids.

Price range $50 – $60. On Ebay I bought at the lower price.
