If you're exploring lapidary tools and asking "Should I buy a flat lap or a cabbing machine?", you're not alone. This is one of the most common questions we hear at Love Agates, especially from artists working with agates, jaspers, and other lapidary stones.
Both machines can shape and polish stone beautifully—but they're designed for different styles of lapidary work. Choosing the right one depends on what you want to create, how you like to work, and where you see your lapidary journey going next.
Let's break it down so you can make a confident, informed decision.
What Is a Flat Lap?
A flat lap machine uses horizontal, spinning discs coated with diamond grit. You work the stone flat against the surface, moving through progressively finer grits to shape and polish.
Why Flat Laps Are Popular
Flat laps are known for their versatility. They're often the first major lapidary machine people invest in—and many artists continue using them even after expanding their workshops.
Flat laps are ideal for:
If you enjoy creative freedom and working directly with slabs, a flat lap offers excellent control and precision.
Flat Lap Considerations
While you can make cabochons on a flat lap, creating smooth, even domes takes more time and technique. Flat laps excel at flat surfaces rather than high-speed cabbing.
What Is a Cabbing Machine?
A cabbing machine uses vertically mounted grinding wheels, usually arranged from coarse to fine. Stones are shaped along the curved edge of each wheel.
Why Cabbing Machines Are Preferred for Cabochons
Cabbing machines are purpose-built for domed cabochons. Once you develop wheel control, they allow for fast, repeatable results with consistent shapes.
They're ideal for:
Cabbing Machine Considerations
Cabbing machines take up more space, require water management, and typically involve a higher upfront investment. They're less flexible for flat or geometric lapidary work.

A Love Agates Perspective
At Love Agates, we see many artists start with a flat lap because it encourages creativity and experimentation. Over time, some add a cabbing machine, while others stay with their flat lap because it fits their artistic style perfectly.
There's no wrong choice—only the tool that supports how you love to work stone.
The best lapidary machine is the one that keeps you excited to sit down, turn it on, and create.
