These work perfectly with our SpeedSetter easy collar set tool (3d printed plastic).
Note: If the collar does not freely slide onto the shank of your bit, DO NOT FORCE IT and reach out to us immediately. If you are experiencing issues or have concerns with the collars, please reach out to us at firstname.lastname@example.org
I have only used them on a couple projects, but they have done what I wanted them for. Fit is good and they stay in place. Won't hesitate to buy more as my bit collection grows.
Great customer service and excellent product
Consistent, repeatable tool change. Excellent!
Seems to be a quality item and very useful tool, fast shipping and a good price
I am beyond satisfied with not only the collars - but with the Speed-Set tool, ALSO. I haven't, as yet, had the opportunity to put the kit to task, but I already KNOW that all is going to be just fine. The tool is very well made, and will serve to be a real benefit to my workflow.
