Crafted with high-speed steel (HSS-E) and coated with a durable Titanium Nitride (TiN) layer, this countersink offers exceptional hardness, heat resistance, and extended tool life. The 90° hole type ensures a precise and consistent angle, allowing for clean and uniform countersinks in a variety of materials. The TiN coating further enhances the tool's performance by reducing friction, preventing chip build-up, and promoting smooth chip evacuation.
