Larger cuts, higher throughput, and professional-grade precision
When your work demands more cutting depth and consistent production output, the 20" Covington 700 Series Slab Saw delivers the power and stability required for serious lapidary operations. This model gives you the same trusted engineering of the 700 Series—just scaled up for larger rough and heavier-duty workloads.
Made for Bigger, Cleaner, More Confident Cuts
The 20" blade and immersion-style lubrication system work together to produce smooth, chatter-free slabs even on dense, high-value material. The blade draws cutting oil directly from the tank as it spins, reducing friction and producing straighter, cleaner surfaces that require less post-processing.
Whether you're slabbing large nodules, wide chunks of petrified wood, or oversized agates, this saw gives you the dependable accuracy needed to maximize usable material and reduce waste.
A Workflow Booster for Small Production Shops
With its six-speed power feed, automatic shutoff, and adaptive clutch, the 20" model keeps you in control while cutting faster and more efficiently. Its larger capacity means fewer cuts per stone, and the cross-feed design allows slabbing up to 8 inches without reclamping, saving valuable time during production runs.
This saw is built for cutters who move a lot of rock—and want a machine that can keep pace.
Engineered for Longevity
Just like the rest of the 700 Series, the 20" model is built on a welded steel chassis with a powder-coated finish for long-term protection. The X-pattern tank support keeps everything square, ensuring a tight, reliable seal over years of heavy use. The sealed, greased-for-life arbor bearings reduce maintenance so you can stay focused on your work.
