BOSCH® MULTIMATERIAL Circular Saw Blades provide ultra clean cuts in aluminium, plastic and epoxy, particle board and MDF. MULTIMATERIAL blades feature precision ground teeth which are made from high quality carbide. The teeth are mounted to a hardened steel body with an optimised negative rake geometry that ensures an exceptional cut quality and a long tool life. They also feature a fully functional, PTFE (Polytetrafluoroethylene) coating. This coating reduces friction and heat during cutting whic extends blade life. It has an additional benefit of protecting the blade body from corrosion.  Features Functional PTFE Blade Coating - Reduces friction while cutting and decreases gumming on the blade body, Fully Ground Teeth - Provides clean and smooth cuts, Negative Rake Tooth Geometry with Triple Chip Grind - Permits cutting of non-ferrous metals and design reduces clogging, High Quality Carbide - Ensures good blade lifetime, Hardened Steel Body - Permits pecise and stable cuts, Specifications Blade Diameter: 184 mm (7-1/4"), Bore Diameter: 20 mm, Kerf Thickness: 2.0 mm, Plate Thickness: 1.5 mm, Tooth Count: 60T, Tooth Hook Angle: -5°, Tooth Configuration: HLTCG (High-Low Triple Chip Grind), Safety Information Maximum RPM: 8.000, Recommended PPE (Personal Protective Equipment):, Safety Glasses, Safety Gloves, Hearing Protection, Respiratory Protection, Material Suitability Aluminium and other Non-Ferrous Metals, Plastic & Epoxy, Particle Board, MDF, Includes Reduction Rings (x2):, 20 mm to 16 mm, 20 mm to 15.875 mm (5/8"),
