The grinding wheel consists of quality steel discs with U-shaped teeth that are pressed from a single piece. A special hardening program brings the teeth to an exact hardness level, ensuring minimal wear during sharpening and dressing. Wavy support discs between the tooth discs provide the tooth roller with stability and strength. The replaceable roller can be used until the teeth are completely worn out. The dresser features a nipple for pressure lubrication, which is essential for high rotational speeds and a long lifespan of the rollers. A stable handle made of hardwood allows for a firm, comfortable, and two-handed grip. Support noses facilitate the even application of the roller to the grinding wheel and simplify lateral movements to dress the entire width of the grinding wheel. A protective shield prevents sparks from spraying towards the face and hands.
