SK clamping collets are a type of tool holder used in CNC machining and milling operations. They are designed to securely hold cutting tools, such as drills or end mills, in place during machining processes.

The term "SK" refers to the standardized taper used in these collets. SK collets have a taper angle of 7 degrees, making them compatible with SK tool holders and spindles.

The clamping mechanism of SK collets involves a series of slits or slots cut into the collet body. When the collet is inserted into the tool holder and tightened, these slits compress, gripping the tool tightly.

SK clamping collets offer excellent tool concentricity and stability, ensuring accurate and precise machining results. They are widely used in various industries, including automotive, aerospace, and general manufacturing.

It is important to select the correct size and type of SK collet for the specific cutting tool being used to ensure proper clamping and performance.
