Collets and Sleeves SMC Milling Chuck Sleeves • One-piece design. • Cutting tool must be cylindrical and have a through hole when using coolant. • Sleeve must be inserted completely into the milling chuck until shoulder mates against the chuck front face. • Cutting tools must be in full contact with the sleeve bore length (L9). • Maximum collapse is h6. • Metric and inch bores are available.
