Bottom vs. Top Saw Arbor

At Xtra Sharp, we exclusively produce straight line edgers with bottom saw arbor design.

• Compact / Advanced
SA-12: Designed for small workshops
SA-18 / SA-20 / SA-22: Perfect for heavy-duty applications


Compact Advanced Edgers

• Enhanced Safety
When the saw blade is below the table, the force applied is going downward, greatly reducing the risk of kickback to a minimum.

Downward Force

• Low Gravity Center Design
Having a rip saw with bottom arbor helps to lower the center of gravity, increasing the machine stability and consequently improving the cutting accuracy.

• Chain Conveyor
To ensure long lasting performance, the chain conveyor is made from cast iron with guide rail configuration consisting of 9 V-shaped ways. Its dual chain, one on each side of the saw blade, offers great stability, while ensuring perfect cutting accuracy. This design mostly explains the price difference with a conventional top arbor rip saw.

• Glue Line Cuts
Both machines can perform “Glue Line Cuts” to prepare the edge surface of lumber before gluing/clamping processes.
