Key features and applications

The BOSS Fissure Vertical Resaw is engineered to deliver precision resawing, exceptional reliability, and high production output in a compact footprint. Built for demanding sawmills, secondary wood manufacturers, millwork shops, flooring producers, and component manufacturers, the Fissure combines industrial-grade construction with advanced controls to maximize productivity while minimizing floor space.

Designed around a heavy-duty steel frame and precision-machined components, the Fissure features a full-width cast iron work table, precision multi-roller fence with digital positioning, and replaceable pressure guides that maintain accurate, repeatable cuts throughout extended production runs. Pneumatic blade tensioning, automated self correcting blade system, intuitive touchscreen controls, and a VFD Variable Frequency Drive delivering infinitely variable feed speeds allow operators to quickly optimize performance for changing material sizes and production requirements. 

Heavy-duty direct drive

Unlike conventional designs where bearings are mounted within the drive wheel, the Fissure’s drive wheel is supported by precision bearings mounted directly on the drive shaft. This superior configuration increases structural rigidity, reduces deflection under load, and delivers exceptional cutting stability and long-term reliability.

Easily adjustable tilt angle

An adjustable tilting side grid that can be easily positioned from 0–45 degrees to accommodate a wide range of material profiles and cutting applications. This versatile adjustment allows operators to securely position irregular, angled, or specialty-shaped materials while maintaining precise blade alignment and consistent feed pressure. The result is greater flexibility, improved cutting accuracy, and the ability to process a broader range of materials with exceptional control.
