Introducing the Vortex HSS Slitting Saw—a precision tool crafted for machinists who demand clean, accurate slots in metal. This 4" imperial slitting saw is built for reliable slotting on standard milling machines, delivering consistent kerfs and long tool life.

• Diameter: 4" (102 mm)
• Bore: 1" (25.4 mm) for sturdy arbor mounting
• Width: 5/32" (0.15625")
• Teeth: 100 teeth for fine, controlled cutting
• Tooth pitch: Fine-pitch design for precise slotting
• Material: High-Speed Steel (HSS) with a bright finish
• Ground geometry: Hollow ground to the bore to improve side clearance and reduce rubbing
• Kerf tolerance: ±0.001" for tight, repeatable slots
• Arbor compatibility: Suited for standard 1" slitting saw arbors on common milling machines

The combination of high-speed steel and hollow-ground construction provides durable performance during slotting tasks. With 100 teeth on a 4" diameter, the saw delivers smooth, precise cuts in steel, aluminum, and other alloys while maintaining a clean kerf. The fine pitch minimizes per-tooth load, helping to reduce heat buildup and prolong tool life, so you can complete multiple slots with confidence and reduced finishing work.
