This product excels in woodworking applications, processing wood or soft non-metallic materials with ease. However, it is not suitable for metal or non-ferrous materials, as such use will quickly damage the tool. To ensure optimal performance and tool longevity, adhere to the recommended maximum speeds: less than 40mm drilling diameter at 2000rpm; 40mm or greater at 1200rpm. Please note that this bit is intended for use on fixed equipment such as bench drills, vertical drilling machines, and CNC carving machines, and should NOT be used with handheld power tools like hand drills or electric drills. Wide Applications: Our drill bit is adept at cutting through any wood and wood products, easily enlarging holes, and boring any arc of a circle. It's especially useful for tasks such as boring concealed hinges and door locks, with a cemented carbide tip that ensures clean cuts. Whether you're working on furniture like drawers or on plastic and wood products, this bit is your go-to tool for precise perforation. For best results, start at a very low speed for positioning and gradually increase speed once the position is established. When drilling, adding water for lubrication can help reduce temperature and extend the bit's life. Two Spurs & Center Spur: The two spurs and sharp center spur ensure repeated, clean, and accurate hole cutting. The center spur is instrumental in locating the center of your hole with precision. Special Design: Our bit features a small incision resistance to facilitate faster opening speeds. The arc curve design head aids in efficient chip removal and stability during drilling, leading to neat perforations without tremors or broken edges. Universal Shank: The round shank is constructed from solid hardened steel for maximum hardness, ensuring compatibility with various woodworking machines. This universal design allows for widespread use across multiple drilling applications.
