A SK10 collet is a precision-engineered tool component. It is typically made from high - quality alloy steel, which offers excellent hardness and durability, ensuring a long service life even under demanding machining conditions. This collet is designed to firmly hold cutting tools or workpieces in machining operations. It has a relatively small but well-defined clamping range, often suitable for gripping slender or miniature tools and parts, with diameters usually falling within a specific, narrow range. For instance, it might be ideal for tools with diameters ranging from a fraction of a millimeter up to a few millimeters, depending on the specific design. The SK10 collet features a unique tapered inner bore. When the collet nut is tightened, the collet's segments are forced to move radially inwards due to the taper, creating a secure and concentric grip on the inserted object. This design allows for high - precision clamping, minimizing tool run - out. In fact, it can achieve a very low total indicated TIR (TIR), often within the range of a few micrometers. This high level of precision is crucial for applications such as micro - machining, where even the slightest deviation can affect the quality of the final product. Commonly used in high - precision machining equipment like micro - milling machines, small - scale lathes, and specialized drilling rigs for printed circuit board (PCB) manufacturing or the production of miniature mechanical components, the SK10 collet plays a vital role in ensuring accurate and repeatable machining processes. Its compatibility is limited to machinery that is designed to accept SK10 - type collets and their associated holders, which are engineered to work in harmony to transfer the clamping force effectively and maintain the required precision.
