Abstract
A hole-saw, including a sidewall and an endcap, is provided. The endcap includes projections that fit within notches of the sidewall to form a brazed or welded joint that couples the endcap to the cylindrical sidewall. The projections extend through the notches and are brazed or welded to the base of the sidewall. The endcap couples to the sidewall to form a cylindrical hole saw body. The endcap rotates and supports the hole-saw during operation.
