Description

SC series straight shank spring collets are manufactured from high-quality spring steel with overall quenching and precision grinding, the standard matching accessories for power tool holders, specially designed for heavy-duty cutting and high-precision machining.
  1. High-precision manufacturing ensures ≤0.008mm runout accuracy, delivering excellent machining precision and surface finish.
  2. Powerful clamping design provides significantly higher gripping force than ER collets, effectively preventing tool slippage during heavy cutting operations.
  3. Complete size range from SC16 to SC42 covers all common tool diameters from 3mm to 36mm, meeting various machining requirements.
  4. Standard straight shank design is fully compatible with all mainstream SC power chucks and tool holders on the market.
  5. Hardened and ground surface provides superior wear resistance and corrosion resistance, extending service life.
  6. Both metric and inch sizes are available to meet the needs of different regions and applications.
