Thürmer Tools HSS-TiN PRO Countersink 90° with 3 flutes is a professional precision tool engineered for efficient, consistent countersinking. Manufactured from HSS and coated with TiN (Titanium Nitride) to reduce friction and heat build-up, improve chip flow, and extend tool life in repeated operations. The 90° geometry and three cutting edges ensure smooth, controlled machining and produce clean, accurate, low-burr countersinks—ideal for preparing screw seats and achieving a high-quality finish. Suitable for workshop and installation use across a wide range of materials, including metals, plastics, and wood.
