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.
Claims20
A hole-saw, comprising:
- an endcap;
- a sidewall forming a hole-saw body when coupled to the endcap, the sidewall comprising:
- a cutting edge at a first end of the sidewall;
- and
- a second end coupled to the endcap;
- wherein the endcap comprises a first endcap segment having two opposing outer ends and a second endcap segment having two opposing outer ends, wherein the first and second endcap segments are formed as separate, discontinuous, identical segments that are coupled together with different orientations to form the endcap;
- wherein the two opposing outer ends of the first endcap segment and the two opposing outer ends of the second endcap segment contact the sidewall and couple the endcap to the sidewall.

A hole-saw, comprising:
- an endcap, comprising:
- a plurality of endcap segments coupled together, each of the plurality of endcap segments comprising two opposing outer ends;
- a hub that couples to an arbor, wherein the hub is formed from overlapping central sections of the plurality of endcap segments;
- and
- a sidewall forming a hole-saw body when coupled to the endcap, the sidewall comprising:
- a cutting edge at a first end of the sidewall;
- and
- a second end coupled to each of the two opposing outer ends of each of the endcap segments of the endcap.

A hole-saw, comprising:
- an endcap comprising:
- a first endcap segment comprising opposing outer ends and a first segment bore located between the opposing outer ends of the first endcap segment;
- a second endcap segment comprising opposing outer ends and a second segment bore located between the opposing outer ends of the second endcap segment;
- a sidewall forming a hole-saw body when coupled to the endcap, the sidewall comprising:
- a cutting edge at a first end of the sidewall;
- and
- a second end coupled to the endcap;
- wherein the opposing outer ends of the first and second endcap segments are coupled to the sidewall coupling the endcap to the sidewall;
- wherein the first and second endcap segments are coupled together such that the first and second endcap segments form a hub and the first segment bore aligns with the second segment bore to form an endcap bore that is configured to couple the endcap to an arbor.
