Benjamin's Best High Speed Steel 3/4" x 1/4" Convex Parting Tool with Diamond cross section - 16"Long. This convex design has a sharper point for faster and easier parting. It provides less binding and easier tool removal from your work. The benefit of the diamond cross-section is that the friction is significantly reduced, making for both easier control and reduced heat build-up. This is important when parting Hardwoods which can crack if overheated.
