How to Select Circular Blades for Log Roll Slitters?

Here're some tips about the selection of circular blade for the log roll slitters:

• Generally, we use two types of materials: high-speed steel blade and tungsten steel blades for #log roll cutting machines.
• For masking tape, double-sided tape, duct tape, Bopp tape, both blades are ok.
• When it comes to foam tape, the tungsten blade is highly recommended, as we all know blade wearing a lot for cutting foam tapes. With tungsten blades, well, blade just need to sharpen once after 20,000 cuts; with high-speed steel blade requires for sharpening just after 200cuts.
• When tungsten blades NOT recommended: very hard materials like a protective film, big yard BOPP packing tape, crisp materials like PET film, etc.
• Blade size (OD): log roll outer diameter-(minus) inner core diameter+(plus) blade clamp diameter. Generally: most regular sizes are: 180mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm and 600mm.
