7-Piece Drill Cutting Discs, HSS Disc Drill Blades with 60mm Hex Shank (1/4"), Mini Circular Saw Blades for Wood, Plastic, and Metal

High-strength carbon steel arbor: Made of high-strength carbon steel with a nickel-plated finish for extreme hardness and a longer lifespan, it resists wear, corrosion, and frequent use without breaking.

HSS Circular saw blade: The circular saw blade is made of high-speed steel (HSS), robust and sharp enough to maximize cutting speed and achieve perfect results.

Versatile and efficient: The mini cutting discs fit most electric drills and are very easy to install and replace.

The matching 1/4" hex shank makes it powerful and perfect for PVC pipe, plastic pipe, and wood. It can also be used to cut soft metal pipe, but use coolant or water when cutting soft metal pipe to prevent the circular saw blade from overheating. Installation steps: outer bar → saw-tooth washer → blade → flat washer → screws. Tighten the screws. An oil film protects the blade. Once set, connect it to a drill and begin use. Note: For your safety, please wear gloves and safety glasses and be careful of sparks when using circular saw blades. The maximum speed of the saw blade should not exceed 20,000 RPM.
