How it works

Using an induction system, the tool holder clamping area is heated for a few seconds and a tool is inserted. Once the holder cools, the holder and tool essentially behave as one piece. Incredible concentricity and rigidity are achieved by the uniform force on the tool.

Advantages of Heat Shrink Tool Holders

• Incredible concentricity: better than 0.0001 inch is easily achievable!
• Highest torque transmission: 2-4 times that of a collet
• Better tool holding power for a more reliable interface
• Increased tool life
• Works with HSS and Carbide tools
• Better surface finish due to excellent rigidity and less vibration
• Excellent repeatability when inserting new tools
• Less wear and tear on the spindle taper and bearings
• Smaller tool holder diameters mean reduced workpiece interference
• Increased speeds and feeds are possible due to reduced tool holder weight and inherently balanced design
• Fast tool changes: remove tools in 4-6 seconds, insert tools in 5-7 seconds
• Lower tool holder cost
