Overview The Independent Chuck is a four‑jaw, independently adjustable lathe chuck designed for holding cylindrical and irregular‑shaped workpieces. The spindle housing and jaws are manufactured from hardened steel for wear resistance and dimensional stability. Jaws conform to American Standard Tongue and Groove and are fitted with a quick‑change jaw system. Base jaws include a thread for spindle adjustment and stepped reversible top jaws; to reverse a top jaw, release the jaw mounting bolt.Features & Benefits Forged steel body for consistent concentricityHeavy‑duty construction suitable for toolroom and shop useFour independently moving jaws allow secure gripping of irregular shapesAdapter plates available to fit most common spindles5" and 6" sizes supplied with solid jaws only8" to 20" sizes available with two‑piece jaws; all sizes can be ordered with solid jawsApplications Tool room and prototype machiningGrinding operations requiring accurate holdingWorkholding for odd‑shaped or asymmetrical partsTechnical specifications Body material: forged steelJaw material and spindle housing: hardened steelJaw configuration: four independent jaws, adjustable individuallyJaw standard: American Standard Tongue and GrooveJaw types: solid jaws (5" and 6"), two‑piece jaws (8"–20"); all sizes available in solid jaw optionAdapter plates: available to fit most common spindles
