Compatibility
Accepts DC-65 Varibore collets with ±0.5 mm accuracy specification; supplied with smooth or serrated gripping surfaces.
Interchangeable with B-200 series power chucks (quick gun-change pull-back power chuck).
Construction & protection
Vulcanized rubber between hardened steel collet segments provides protection against coolant and chip ingress.
Fully sealed design with O-ring seals to prevent coolant and chip ingress; no grease required for operation.
Performance & mounting
Pull-back action: collet is pulled into the chuck to close and pushed out to open; back stops are not provided.
Direct mount to lathe spindle or via precision adaptor plate; supplied with mounting bolts and custom-machined drawtube connector for immediate installation.
Direct mount design ensures high concentricity suitable for higher-speed operations where a conventional 3-jaw chuck may be less appropriate.
Durability & design
Case-hardened body to optimise rigidity, strength and long service life.
Short body with wide gripping range enabled by DC Varibore collets; low-profile nose diameter for improved tool clearance.
Additional notes
Counter boring and special profile shapes available on request.
