Key features

• •Product Name::Diamond coated hole saw drill bit, can achieve high precision and smooth cutting, no edge breakage, with good toughness and high strength.
• •Product material: high-quality emery, the surface treatment is nickel-plated, which can extend the service life and enhance the surface corrosion resistance. These diamond drill bits are made of high-speed steel with a nickel-plated coated body that is corrosion-resistant and has a long service life.
• •Features: Diamond coating increases drilling speed and sharpens drill bits. Electroplated diamond is uniform and more wear-resistant, maximizing performance and maintaining sharper cutting edges than traditional carbide or bimetal hole saws. In addition, the special design with clearance holes facilitates the entry of cooling water and the escape of chips from the borehole, making the drilling process easier.
• •Applications: Diamond-coated hole saw drill bits are ideal for drilling glass, ceramics, porcelain, tiles, limestone, slate, marble, light stone and fiberglass. Low speed use is required; Always use lubricant (water) when machining, otherwise the hole saw will burn. Not suitable for drilling of tempered glass, plastic and wood.
• •Package contents: 10PCS diamond coated hole saw drill bits with a drilling diameter of 3mm.
