General description This is a 10.0 mm TCT (tungsten carbide tipped) drill bit designed for precise drilling in hard materials. It is suitable for use with stationary machines and is ideal for drilling steel, cast iron, bronze alloys, and manganese steel. The drill bit features a high-quality tungsten carbide tip that allows for efficient drilling in materials with hardness up to 50 Rockwell C. Its design includes four ground facets that reduce drilling pressure and ensure accurate centering, resulting in better performance and precision. The body is made of chrome-vanadium steel hardened to 56 Rockwell C, providing excellent wear resistance and durability during intensive use. Technical specifications Type: TCT (tungsten carbide tipped) drill bit Diameter: 10.0 mm Total length: 133 mm Working length: 87 mm Material: Chrome-vanadium steel with TiN coating TiN hardness: 50 Rockwell C Recommended coolant: Emulsion 3-6% Application: Drilling metals, cast iron, bronze alloys, and manganese
