2pcs 9/16" Twist Drill Bits M35 High-Speed Steel HSS Round Shank 6" Long
Description:1. Crafted from high-speed steel, offering improved hardness, heat resistance, and wear resistance to extend tool life.2. Black oxide coating on twist drills can enhance corrosion resistance and improves surface hardness, also reduces glare while adds decorative appeal, providing both functional and aesthetic benefits.3. Split point tip and twist design increases cutting speed while easily self-centering to prevent movement. The twisted design of the drill bit quickly removes drilled chips,resulting in cleaner, more precise cuts, improving overall drilling efficiency.4. Use lubricant like cutting oil or coolant, especially when drilling metal, to reduce friction and heat, further prolonging the drill bit's lifespan.5. For drilling on thin aluminum, copper, wood, PCB board.
