Cutting blades for rotary tools, mini HSS circular saw blades for cutting wood, plastic and metal (8 pieces)

6 Pieces Mini Cutting Discs for Rotary Tools - Rotary Tool Accessories, Disc Drill Blades and 3 Mandrel Rods Made of high-speed steel. High-speed steel: hardened at a temperature of approximately 1205~1215℃, hardness 61~66.2HRC. The super hardness and abrasion resistance extend the service life of the saw blades or mini circular saw discs. The cutting discs are designed for cutting wood, plastic, fiber, glass, aluminum alloy, soft metal, etc. Drill disc sizes: 22 (25, 32, 35, 44, 50) * 0.8 * 6.35 mm diameter; Inner diameter: 6.35 mm; Thickness: 0.8mm Chuck Shank Size: 1/8 inch (3mm) and 1/4 inch (6mm) Cutting discs with a 3mm (1/8 inch) shank chuck are compatible with most rotary tools, pneumatic tools, or electric grinders. Easy to install, these circular saw discs are suitable for DIY projects, craft enthusiasts, and anyone working with wood, aluminum, plastic, or doing DIY projects. Proper Use The entire chuck shank must be inserted to the end to prevent unnecessary damage and injury. Indeed, when the machine speed is too high, the chuck can twist or the cutting angle can become off-center. Please tighten the screw on top before use to prevent unnecessary damage and injury, as the electric grinder is a high-speed tool. To meet various requirements, ensure safe operation, and extend the lifespan of the HSS cutting blades and mini-saw blades, the rotation speed should not exceed 20,000 rpm. Diameter (in mm): 50. Blade Material: Cemented Carbide. Cutting Type: Finishing.
