PHASE 2, 6 1/2 " 3-Jaw Chuck 1 1/2" Hole Self Centering Jaws

The PHASE II 6 1/2" 3-Jaw Self-Centering Lathe Chuck with 1 1/2" Through-Hole is a high-precision, heavy-duty workholding tool engineered for professional machinists, hobbyists, and production shops. Ideal for turning, facing, and machining small to medium workpieces, this chuck combines fast self-centering operation, reliable gripping force, and durable construction for consistent accuracy in all your lathe projects.

Precision Self-Centering 3-Jaw Design

Featuring self-centering jaws, this chuck allows all three jaws to move simultaneously, providing quick and accurate alignment of round or hexagonal stock. This reduces setup time compared to independent jaw chucks and ensures concentricity and smooth operation on every piece.

Compact 6 1/2" Diameter with 1 1/2" Through-Hole

The 6 1/2" chuck diameter is perfect for medium-sized workpieces, while the 1 1/2" through-hole enables bar stock or long material to pass through the spindle for continuous machining tasks, making it ideal for small production runs, DIY projects, and precision workshop applications.

Durable Construction & Reliable Performance

Built from high-strength cast iron or alloy steel, this PHASE II chuck is precision-machined, hardened, and ground to maintain consistent jaw movement and long-lasting durability. Hardened jaws provide a secure grip on workpieces, while the robust body resists wear under demanding shop conditions.

Smooth Operation & Accurate Clamping

The precision scroll mechanism ensures even jaw movement and stable clamping, reducing runout and enhancing machining accuracy. Whether you’re turning, facing, or performing light-duty drilling, this chuck provides the accuracy and reliability required for professional and hobbyist projects alike.
