Collet Chucks & Tool Holders • MILLING

HSK63A ER Collet Chuck

• Dynamically balanced to G2.5 25,000 RPM to meet today's demanding need in aggressive high speed machining

• Concentricity is less than 0.0001" from taper to end mill pocket

• In a generic standard ER collet nut, an internal ring is off-centered so that an ER collet can be easily snapped into it and

holds the ER collet in place. To minimize this off-centering,

SHARS ER collet nut is optimized to Collet Nut Diameter Projection Order
distribute the flat sides' area to off-set
the off-center. ER collet nut is also Taper Series Range D L No.
