5pc Imperial

Titanium-coated spiral step drill

Product Features：

The step sizes strictly follow the Imperial (inch) standards and are specially used for processing or repairing hole systems that conform to Imperial sizes (such as American standard equipment, old machinery, and pipe fittings). Titanium coating greatly enhances surface hardness, wear resistance, and heat resistance, reduces the friction coefficient, and is suitable for higher speeds, harder materials, or longer continuous processing.
