Product Overview
The Smooth Dovetail Jaws #3 are a premium accessory designed specifically for Oneway StrongHold chucks, a leading solution in the lathe market. Crafted from hardened black steel, each jaw delivers exceptional strength while maintaining a lightweight profile of just one pound. The external and internal jaw components are engineered to work together seamlessly, providing a secure grip on a wide range of workpieces, from delicate vases to robust bowls. In the closed position, the compression mode measures 3 5/8 inches, while the expansion mode reaches 4 3/8 inches, offering flexibility for various diameters. When fully opened, the jaws extend to 5 inches in compression mode and 6 inches in expansion mode, ensuring ample clearance for larger items. The compact dimensions of 4 × 2 × 4 inches make storage and handling effortless, and the black finish not only adds a professional aesthetic but also resists corrosion and wear over time. Designed with precision machining tolerances, the jaws fit Oneway Model #3236 chucks perfectly, eliminating any wobble or misalignment that could affect machining accuracy. ![[Product front view showing all components]](https://www.glowshop.store/wp-content/uploads/2026/07/06c34b8293ba42ecabc39c30a771054a.jpg)
Usage
These jaws excel in a variety of workshop environments, from hobbyist home shops to professional manufacturing floors. They are ideal for turning operations that require a stable, consistent hold, such as shaping large ceramic bowls, polishing decorative vases, or machining wooden bowls for culinary applications. The robust construction allows the jaws to withstand the high torque generated by powerful lathe motors, making them suitable for both low‑speed precision work and high‑speed material removal. Because the jaws are compatible with the Oneway StrongHold chuck series, they integrate effortlessly into existing setups without the need for additional adapters or modifications. Users who demand accuracy in fine detail work will appreciate the smooth transition between compression and expansion modes, which reduces the need for frequent adjustments during a job. The black coating also minimizes glare under shop lighting, helping operators maintain clear visibility of the workpiece. Whether you are a seasoned machinist, a craftsperson creating artistic pieces, or a technician maintaining equipment, these jaws provide the reliability and performance needed to achieve consistent results.
