Mirror Finished Taper ground to AT3 or better specification ensures 80% or more contact with spindle to reduce harmonics, improve runout tolerance and deliver consistence performance / Flange Contact Precision mill finished from multi-tasking Mazak machine on the flange face to eliminate the 1/8" gap between flange and spindle nose to minimize vibration / ER Collet Nut No longer having an off-center internal collet ring, this collet nut's internal clamp is designed with balance in mind while it's easy to snap-in snap-out ER collet / Dual Contact With simultaneous contact on taper and flange face between the spindle and tool holder, dual contact tooling eliminates the 1/8” gap between the flange face and the spindle nose to increase rigidity, minimize vibration, extend cutting tool tool life, and greatly improve workpiece surface finish at aggressive speed & feed / DONE IN ONE By utilizing DONE IN ONE capability from Mazak Integrex machine with a second turning spindle, all processes from raw bar stock material to final machining in just one machine to improve machining accuracy and streamline production output / High Torque Collet Nut Innovative coating process significantly increases the clamping force by 75% compared to standard ER collet nut. More gripping force provides better rigidity and reduces the possibility of losing grip on the round shank which lead to expensive damage on cutting tools and work piece material / SHARS Dual Contact tool holder can only be used on machine center with dual contact spindle / Compatible with BIG-PLUS spindles. / *BIG-PLUS is a trademark of Daishowa Seiki Kabushiki Kaisha; Big Daishowa Seiki Co., Ltd., Corp. / Compatible with BIG-PLUS spindles, but not licensed. / Shank Size: CAT40 / Projection Length: 4 / Collet Nut Style: Hex / Maximum Torque Ft/Lb: 75 / Coolant Through: Thru Spindle & DIN-B Flange / Collet Series: ER20 / Collet Chuck Style: Standard / Collet Nut Diameter: 1.1 /
