T.J. Davies Co.

T.J. Davies Co. began twenty years ago as a blue label supplier of tool holders and tool holder components to the major rotary tooling manufacturers. For the last ten years, they have exclusively manufactured their own line of retention knobs. Their manufacturing process exceeds industrial standards.

The new machines manufactured have higher horsepower, more rigidity, and very high RPM's. It is more critical to select a knob made to the highest quality standards.
