Heat-Activated Toolholder
Constructed with an inside diameter slightly smaller than the shank diameter of standard cutting tools, the Shrinker heats up
Constructed with an inside diameter slightly smaller than the shank diameter of standard cutting tools, the Shrinker heats up quickly by using a heat induction unit to expand the inside diameter. As the holder cools, the thermal contraction exerts a uniform pressure, allowing the toolholder to shrink down around the tool, keeping the shank securely in place with its concentric gripping strength.

The heat-activated toolholder has high concentric running accuracy, maximum guaranteed concentricity of 0.0002 in. or better, a safe frictional transfer of force, and it is suitable for high speed cutting applications. The Shrinker includes a transferable torque higher than that of standard milling chucks or collet chucks, a high radial stiffness, and simple tool clamping with no moving parts.

The induction heating unit is available in two vertical and two horizontal models. Several options are available including a sensor that detects the amount of heat introduced into the toolholder and shuts the machine off automatically to prevent overheating of the toolholder. Accessories include depth-setting units, locking rings, induction spacer rings, HSK coolant tubes, installation wrenches, and indirect coils for the heating unit.
