HOW DOES A TOOL HOLDER WORK?
Let’s talk about the basic mechanics of how a tool holder works. The taper on the tool holder's shank fits into the matching taper inside the machine's spindle, securing the assembly in place. This precision fit helps to minimize runout (wobble) and ensures that the cutting tool remains perfectly aligned with the spindle's axis of rotation. Tool holders are held into the spindle through the retention system, with reliance on a high quality pullstud screwed into the tool holder. In addition, the chuck, collet or other clamping mechanism within the tool holder grips the cutting tool shank with tremendous force, preventing any unwanted movement or vibration during the machining operation. By maintaining this rock-solid connection between the tool and the spindle, tool holders enable you to push the limits of speed, feed rates and depth of cut. And with the right tool holder, you can preserve the integrity of your workpieces and maximize tool life.
