Abstract
A router bit that includes a shank end, a boring end opposite to the shank end, a drill axis that is defined between the shank end and the boring end, a shank that extends from the shank end and is adapted to engage with a chuck of a router, and a body that extends from the shank to the boring end and defines a non-linear profile. The router bit also includes a pair of cutting edges of the body that helically extends along the drill axis between the shank and the boring end. The router bit also includes a pair of flutes of the body that is defined between the pair of cutting edges and helically extends along the drill axis between the shank and the boring end. The body is configured to cut a non-linear profile into a work piece.
Claims17
A router bit, comprising:
- a shank end;
- a boring end opposite to the shank end;
- a drill axis defined between the shank end and the boring end;
- a shank extending from the shank end and adapted to engage with a chuck of a router;
- a body extending from the shank to the boring end and defining a non-linear profile, the body comprising:
- a base portion extending from the shank;
- a reamer portion extending from the base portion and configured to cut a first portion of the non-linear profile, the reamer portion having a first end positioned proximate to the base portion, a second end opposite to the first end and positioned proximate to a tip portion;
- at least one chamfered cutting edge extending from the first end to at least one planar cutting edge that extends towards the tip portion, and at least one rounded cutting edge extending from the at least one planar cutting edge to the second end of the reamer portion;
- wherein the at least one chamfered cutting edge is configured to cut a pair of top chamfered walls defining the non-linear profile;
- and
- the tip portion extending from the reamer portion to the boring end and configured to cut a second portion of the non-linear profile vertically below the first portion of the non-linear profile;
- a pair of cutting edges of the body helically extending along the drill axis between the shank and the boring end;
- and
- a pair of flutes of the body defined between the pair of cutting edges and helically extending along the drill axis between the shank and the boring end;
- wherein the body is configured to cut the non-linear profile into a work piece.
A method of cutting a non-linear profile into a work piece, comprising steps of:
- engaging a router bit with a portable router, the router bit comprising:
- a shank end;
- a boring end opposite to the shank end;
- a drill axis defined between the shank end and the boring end;
- a shank extending from the shank end and adapted to engage with a chuck of a router;
- a body extending from the shank to the boring end and defining a non-linear profile;
- a pair of cutting edges of the body helically extending along the drill axis between the shank and the boring end;
- and
- a pair of flutes of the body defined between the pair of cutting edges and helically extending along the drill axis between the shank and the boring end;
- introducing the router bit and the portable router to the work piece;
- aligning the body of the router bit with an outer wall of the work piece;
- cutting the non-linear profile into the work piece;
- and
- cutting a pair of top walls of the non-linear profile, via at least one chamfered cutting edge of a reamer portion of the body, in a single pass;
- cutting a pair of first vertical walls of the non-linear profile, by at least one planar cutting edge of the reamer portion of the body, in the single pass;
- and
- cutting a pair of rounded walls of the non-linear profile, by at least one rounded cutting edge of the reamer portion of the body, in the single pass below the pair of top chamfered walls and the pair of first vertical walls.
