Designed for grinding steel. Due to their small size and various shapes, grinding pins are used in areas where grinding wheels cannot reach. PRO Steel grinding pins are useful when you need to grind and deburr small parts that are hard to access or have irregular shapes. The PRO Steel grinding pin set includes five grinding pins that are coated with premium quality abrasive grains. Together with the ceramic bond, this ensures stability and a long lifespan. Use them when you need to grind and deburr hardened and unhardened steel parts that have irregular shapes or are not easily accessible with grinding wheels. The set includes round, half-round, cylindrical, disc-shaped, and conical grinding pins, so you have the right accessory for every job at hand. The cylindrical shank is suitable for keyless chucks.
