The Grizzly G8145Z is particularly known for its robust construction and versatility. It features a powerful 2 HP motor that delivers ample torque for handling both hard and softwoods with ease. The lathe's variable speed control allows users to adjust speeds from 600 to 2400 RPM, providing flexibility for a wide range of turning applications. The 14-inch swing over bed and a 40-inch between centers make it suitable for turning larger pieces, with precise control afforded by its heavy-duty cast iron bed.

The G8146Z model ups the ante with enhanced features geared toward professional woodturners. It boasts a larger 16-inch swing and a 48-inch distance between centers, accommodating more extensive workpieces. The innovative digital readout provides accurate spindle speed and position information, which enhances user precision and convenience. Additionally, the G8146Z comes with an advanced electronic speed control system that maintains consistent speeds under load, ensuring smooth operation no matter the project.

Complementing this impressive lineup is the G8144Z, a lathe designed with both user-friendliness and versatility in mind. With a 1 HP motor, it is perfectly suited for beginners and intermediate woodworkers alike. The G8144Z features a 12-inch swing and a 36-inch bed length, making it an excellent choice for smaller projects while still capable of handling a variety of turning tasks. Its easy-to-use tailstock and tool rest adjustments make setup and operation straightforward, allowing users to focus on their creativity rather than on mechanisms.

All three models come with several safety features, including a quick release tailstock and a spindle lock, ensuring secure operation.
