HOLESAW AND PILOT BIT WITH THREADED TIP |
| 摘要 |
A holesaw assembly includes a holesaw and a pilot bit. The holesaw includes a hollow cup defining a center axis. The cup has a round base perpendicular to the center axis and a peripheral wall coupled to and extending axially forward of the base to a peripheral edge at a free end of the wall. The pilot bit is received in the holesaw along the center axis. The pilot bit has a shaft received in the base, a cutting head coupled to a front end of the shaft, and an at least partially threaded tip coupled to a front end of the cutting head. The holesaw is free of any radial cutting elements disposed inside the cup between the drill bit and the peripheral wall of the cup. |
