Toolholders
The Toolholder is the essential connection between the machining center and the cutting tool. The toolholder fits into and is secured by the machining center’s spindle, and in turn, secures the cutting tool such as a drill or end mill by clamping onto its shank. The taper of the toolholder matches the toolholder interface of the particular spindle. Toolholder tapers are often conical, including CAT and BT taper specifications. A different kind of taper, HSK, is not tapered at all, but instead includes a variety of flanges for securely locking the toolholder in place. Toolholders use different mechanisms for clamping the tool including set screw, collet, hydraulic compression and shrink-fit.

FAQ: Toolholders
What is a HSK toolholder?
HSK, meanwhile, works by elastically deforming the toolholder. Fingers inside the hollow shank of the toolholder clamp the holder by pushing out. High spindle speed helps this interface, because the centrifugal force strengthens this clamping.

How does a hydraulic toolholder work?
The hydraulic toolholder works by using fluid to compress an internal membrane within the holder body. The hydraulic fluid delivers uniform pressure around the membrane allowing it to compress equally around the periphery of the cutting tool. Basically, that’s how the hydraulic toolholder delivers its high concentricity specs.
