Attach tool holders such as collet chucks and end mill holders to your CNC machine’s spindle. For proper operation, choose a knob that exactly matches your collet type and spindle dimensions. All meet industrial standards for tensile and shear strength. These knobs are also known as pull studs.
Knobs with a coolant hole let coolant flow through to protect your tools and workpiece.
