💡 What is a spring collet used for in machining? Spring collets secure round shank tools inside holders during milling and drilling. - They maintain low runout so parts come out with smooth surfaces. - Strong collapse around the tool keeps everything from slipping at high rpm. - Quality steel construction stands up to repeated use in busy shops.
