Hole saw with brazed or welded end cap

The invention relates to a hole saw with a brazed or welded end cap. A hole saw is provided that includes a sidewall and an end cap. The end cap includes projections that fit within the recesses of the sidewall to form a brazed or welded connection to connect the end cap to the cylindrical sidewall. The projections extend through the notches and are brazed or welded to the base of the sidewall. The end cap is coupled to the sidewall to form a cylindrical hole saw body. During operation, the end cap rotates and supports the hole saw. 本申请涉及具有钎焊的或焊接的端盖的孔锯。提供了一种孔锯，该孔锯包括侧壁和端盖。该端盖包括突出部，这些突出部装配在该侧壁的凹口内以形成钎焊或焊接连结部，从而将该端盖连接至该柱形侧壁。这些突出部延伸穿过这些凹口并且被钎焊或焊接至该侧壁的基部。该端盖联接至该侧壁以形成柱形孔锯本体。在操作期间，该端盖使该孔锯旋转并支撑孔锯。
