When you're shopping for industrial woodworking machinery, one of the first decisions is how to hold odd-shaped workpieces securely. The Industrial 4 Jaw Lathe Chuck K72-100 100mm for Woodworking Machine addresses that with a compact four-jaw design. This review looks at the details that matter: capacity, material, and whether this chuck fits your turning needs.
Quick Verdict
At USD 52.97, the Industrial 4 Jaw Lathe Chuck K72-100 gives you a 100mm chuck with a cast-iron body and hardened steel jaws. The four independent jaws are the key reason to consider it: you can move each jaw separately to center non-concentric stock. The clamping tolerance is specified at 0.003 inch / 0.07 mm, which is a tight figure for a compact chuck. If your workpieces stay within its range, this is a solid choice for precise, hands-on control.
Who It Suits
This chuck works well for woodworkers turning smaller pieces that need a firm hold on both internal and external surfaces. The internal jaw clamping range is 0.236 to 1.77 inches, while the external range spans 1.57 to 3.93 inches. The jaws are reversible, so you can clamp around the outside of a cylinder or expand into a hollow interior. That makes it useful for spindles, small faceplates, and other work where you want to switch between internal and external clamping. It's especially handy for shaping handles, tool rests, or small decorative pieces.
What Stands Out
The material choices are worth attention. The chuck body is cast iron, the jaws are 20CR steel, the bevel gears are 40CR steel, and the pinions are 20CR steel. A cast-iron body provides rigidity, and hardened steel components are intended for repeated jaw movement. The chuck diameter is 3.93 inches, and the item diameter is 4 inches / 10cm. With a stated tolerance of 0.003 inch / 0.07 mm, this chuck is designed for accurate centering.
Meaningful Trade-offs
The main limitation is capacity. This is a compact chuck, not built for large bowls or wide stock. Workpieces that exceed the chuck's capacity won't fit. For projects that fit, the adjustability is there, but it's not a one-size-fits-all tool. That's the trade-off for the precise control it offers.
Product Note

At USD 52.97, this compact chuck offers the independent jaw movement that makes it easier to grip irregular pieces. The reversible jaws add flexibility for internal or external clamping. The limitation is the size: it's designed for smaller workpieces, with the internal clamping range starting at 6mm.
Bottom Line
The Industrial 4 Jaw Lathe Chuck K72-100 is a focused tool for woodworking shops that need precise clamping on smaller, non-concentric workpieces. It offers a practical balance of control and price for industrial woodworking when your projects fit within its clamping limits.
