Featuring an 82-degree countersink angle, it allows screws to sit flush or slightly below the surface, creating clean and smooth countersink holes. The five-flute design reduces vibration, enhances chip removal, and provides a smoother drilling experience, extending the bit's lifespan. Made from industrial-grade high-speed steel (HSS), these bits are coated with a Titanium Aluminum Nitride (TiAlN) coating, which increases hardness (94HRC) and heat resistance. This ensures long-lasting sharpness and efficient cutting, even when working with tough metals and high-performance materials. The set includes a 1/4" quick-change hex shank, compatible with most handheld and stationary drills for secure, easy bit changes. It comes with five popular sizes: 1/4", 3/8", 1/2", 5/8", and 3/4", all neatly organized in a durable aluminum case for convenient storage and transportation. Ideal for long-lasting, high-efficiency use in a variety of drilling applications.
