Each Collet has a accurate clamp force up to 1mm (.040” so the Collets are also suited to Hold most Imperial sizes .

Guide to Collet Setups:

1. Familiarize yourself with the ISO30 and ISO40 collet chuck sets. These are commonly used in milling and drilling machines to hold and secure cutting tools.

2. Check the specifications of the collet chuck set to ensure it's compatible with your machine. The set should come with an appropriate adapter for your machine spindle and should be able to accommodate the size and type of cutting tools you plan to use.

3. Take note of the collet sizes that come with the set. The ISO30 and ISO40 ER collet chuck sets we sell include 15 collets, ranging from 3mm to 26mm. This range of sizes should be sufficient for most applications.

4. Choose the appropriate collet for your cutting tool. Collets are selected based on the diameter of the cutting tool, and the set should include collets to fit most common sizes. Make sure the collet is clean and free of debris before use.

5. Insert the collet into the collet chuck and tighten it using a collet wrench. The collet should be snug but not overtightened, as this can damage the collet or the cutting tool.

6. Insert the cutting tool into the collet and tighten the collet nut using a wrench. The cutting tool should be securely held in place, with no visible wobbling or movement.

7. Test the setup by running the machine at a low speed and observing the cutting tool for any signs of vibration or instability. If there are any issues, stop the machine and recheck the collet and cutting tool for proper installation.

8. When finished, remove the cutting tool and collet from the collet chuck, and clean the collet and chuck with a solvent and a soft brush. This will help to ensure that the collet and chuck are clean and free of debris for the next use.

Other useful information:

ISO30 and ISO40 are international standards used to specify the size and type of tool holders used in milling and drilling machines. 30INT and 40INT, on the other hand, are American standards for tool holders.

ISO30 specifies the dimensions and mounting requirements for the spindle and tool holder, with tool holders designed to hold cutting tools with shank diameters ranging from 3mm to 20mm. ISO40 specifies the same for tool holders designed to hold cutting tools with shank diameters ranging from 3mm to 32mm. In contrast, 30INT and 40INT are based on imperial measurements, with tool holders designed to hold cutting tools with shank diameters ranging from 1/8 inch to 1 inch for 30INT and 1/8 inch to 1-1/2 inches for 40INT.

The key difference between ISO standards and American INT standards is the measurement system used. ISO standards are based on metric measurements, while INT standards are based on imperial measurements. This affects the dimensions and tolerances specified in the standard, as well as the range of cutting tool shank diameters that can be accommodated by the tool holder.

It's important to ensure that the tool holder you select is compatible with the machine spindle and cutting tools being used to ensure safe and effective operation. If you have a machine that is designed to use ISO tool holders, it is recommended to use ISO tool holders. Conversely, if your machine is designed to use INT tool holders, it is recommended to use INT tool holders.
