Ozar Knurling Tool Holder 5" x 6 Knurls. Self-centering, robust and strong. It is fitted with standard left and right pattern knurls in fine, medium and coarse pitch.
The revolving head rotates within a 40 degree arc so equal pressure is automatically applied to both wheels. Any pair can be brought to bear on the workpiece, thus 3 different knurling patterns are obtainable without changing the tool. Knurling is usually accomplished by using a lathe.
