CNC precision drill chuck for clockwise and anti-clockwise rotation, DIN 69893, Form A, without coolant supply
Design: Made of special case-hardened steel for highly stressed components, with a core tensile strength of min. 1000 N/mm². Chuck and shank in one piece. Clamping (using a hex spanner) essentially increases clamping force in comparison to conventional chucks. At the same time, this secures the chuck against becoming loose during anti-clockwise rotation or being quickly decelerated from higher speeds.
Taper angle tolerance: AT3
Hardened: 58 ± 2 HRC
Application: Use on CNC machines and machining centres. To mount tools with cylindrical shank.
Scope of delivery: CNC precision drill chuck with hex spanner including sealing disc for coolant drill bits with 3-6 mm Ø.
