General Quality Features:

• High quality spring steel full hardened and ground for proper hardness and toughness, better flexibility and increased grinding quality.
• Concentricity within 5µm for longer tool life and best surface finish.
• The collets are slotted, hardened, ground, polished and tested to 100% concentricity.
• Fine finished surface (Rz ≤ 2.5µm) for higher stiffness, maximum clamping forces, enhanced concentricity and better corrosion resistance due to increased surface contact.
• All edges are deburred and rounded to protect the spindle from inside marks.
