REDUCED VOLUME CUTTING TIP AND CUTTING BIT INCORPORATING SAME |
摘要 |
A cutting bit includes a tool pick having a head and a shank, and a cutting tip having a body, a cap extending frontwardly from the body, and a base extending rearwardly from the body. The base defines an outer diameter of the cutting tip and a substantially flat rear surface at the rear of the cutting tip. A post extends axially frontwardly from a front surface of the head of the tool pick. A cavity extends axially frontwardly into the base from the rear surface of the cutting tip, the cavity having a diameter equal to or less than about 40% of the outer diameter of the cutting tip. When the cutting tip is mounted to the tool pick, the post is received into the cavity and a portion of the front surface of the tool pick mates with a portion of the rear surface of the cutting tip.
