H7669 specifications

The Grizzly H7669 is a well-regarded variable speed mini lathe designed for precision work, especially suitable for both hobbyists and professionals in the woodworking and metalworking fields. This model stands out due to its compact size and powerful features, making it an excellent choice for those with limited workspace who don’t want to sacrifice performance.
