Heat-Activating Systems Shorter cycle time, less cooling downtime, localized heating, and integrated cooling systems are essential for a safe and simple heating system. Shrink Fit heating HEAT systems include induction, hot-air, and open-flame methods, with induction being the easiest and fastest of these systems.

Toolholders

• Slim design.
• Balanced.
• Flatted-style, Weldon®, and Whistle Notch™ shanks can be gripped. Optimal results are obtained with smooth, cylindrical shank cutting tools — without flats and/or notches.
• Avoid using carbide tools with polished shanks. This will reduce torque values by 60%.

HT (High Torque) Shrink Fit Toolholders HT Shrink Fit holders have a high interference level that offers 30–50% greater torque than competitive systems. This line is only to be used with carbide tools because of their low thermal expansion coefficient. These toolholders require a machine with at least 10 kW of power to apply heat quick enough to avoid heating the tool. GP (General Purpose) Shrink Fit Toolholders Ideal Surface Quality GP toolholders enable the use of all materials and extensions because Metric (ISO standard) Ra ≥0,8 μm surface finish. they have lower interference levels. Operators should use this style if not generating high cutting forces. Inch (industry standard) Ra ≥32 μin surface finish.
