Use these collets in milling machines that have an ER-25 collet chuck. With a round face and adjustable body, they compress to grip round-shank drill bits, end mills, reamers, and taps.
To ensure they work with milling machines and tooling made throughout the world, these collets meet both ISO and DIN dimensional standards.
