      Operation And Notice:
      SF DSF Shrink-Fit Holder1
      1

      Before installing cutting tool into shrink fit holder, moisture, oil and other dirt in the hole should be removed completely. Otherwise they might have negative effect for clamping tool and even cause tool to fall during machining.

      SF DSF Shrink-Fit Holder2
      2

      Cutting tool shank tolerance must be h6. Please refer to the following table. Unqualified shank tolerance would lead to insufficient clamping force or cutting tool is unable to install.

      SF DSF Shrink-Fit Holder3
      3

      Setting appropriate heating parameters to prevent overheating according to recommendation of heating machine, material characteristics and wall thickness of shrink fit holder. If the installation fails at the first time, please make sure the shrink fit holder is sufficiently cooled before adjusting the heating parameters and second installation.

      SF DSF Shrink-Fit Holder4
      4

      To keep clamping force and precision, the effective length of cutting tool into the mounting hole of shrink fit holder should be controlled within 3-4 times of the diameter, as shown in the figure.

      ■ Please clean the wall of mounting hole frequently by using nylon brush, which helps reduce carbon deposition and extend the service life of the shrink fit holder.

      ■ Please keep mounting hole installed with cutting tool to avoid oxidation and rust when used shrink fit holder is idle.

      SF-MACHINE Shrink-Fit Principle
      Heating

      When the induction coils works with electricity, the shank of the tool holder which was placed into the coils heating system, is heated and expands.

      Cooling

      Cooling with compressed air to room temperature. (Cooling time is inversely proportional to the power of air compressor)

      Removing

      Heat the holder and remove the tool

      🔒 User-Friendly With High Security

      When the holder is heated to the temperature to remove the tool, the cooling system will be switched on automatically. No bothering to remove the heater.

      Frequently Asked Questions
      Q1 What is a shrink fit tool holder and how does it work?
      A shrink fit tool holder uses thermal expansion and contraction to clamp cutting tools. The holder bore is slightly smaller than the tool shank. When heated by an induction machine, the bore expands, allowing the tool to be inserted. As it cools back to room temperature, the bore contracts and grips the tool shank with extremely high clamping force.
      Q2 What shank tolerance is required for shrink fit holders?
      The cutting tool shank tolerance must be h6. For example, for a shank diameter of 6–10 mm, the tolerance is 0 to -0.009 mm. Using a shank with incorrect tolerance may result in insufficient clamping force or an inability to install the tool at all.
      Q3 What is the runout accuracy and balance grade of these shrink fit holders?
      All shrink fit holders in this series achieve a runout accuracy (X3D) of ≤ 0.003 mm and a balance grade of G2.5 at 25,000 rpm, making them suitable for high-speed precision machining applications.
      Q4 Which interface types are available for the shrink fit holders?
      The shrink fit holders are available in multiple interface types to suit various machining centers, including HSK-A (HSK50A, HSK63A, HSK100A), BT (BT30, BT40, BT50), and SK (SK30, SK40, SK50) interfaces. Both standard SF and deep-reach DSF versions are offered.
      Q5 How should I maintain and clean the shrink fit holder?
      Clean the mounting hole wall frequently using a nylon brush to reduce carbon deposition and extend service life. When the shrink fit holder is not in use, keep the mounting hole fitted with a cutting tool to prevent oxidation and rust inside the bore.
      Q6 What is the recommended effective clamping length for the cutting tool?
      To maintain optimal clamping force and precision, the effective insertion length of the cutting tool into the shrink fit holder's mounting hole should be controlled to within 3 to 4 times the tool diameter. This ensures both secure clamping and accurate tool positioning.
