Abstract

Claims (67)

1 . 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.

2 . The router bit of claim 1 , wherein the pair of cutting edges and the pair of flutes are oriented in an up-cut configuration.

3 . The router bit of claim 1 , wherein the pair of cutting edges and the pair of flutes are oriented in a down-cut configuration.

4 . The router bit of claim 1 , wherein the body further comprises:

a first end;

a second end opposite to the first end; and

a pair of lands extending between the first end and the second end;

wherein each land of the pair of lands defines a non-linear profile extending between the first end and the second end.

5 . The router bit of claim 4 , wherein each land of the pair of lands defines a chamfered profile.

6 . The router bit of claim 4 , wherein each land of the pair of lands defines a curvilinear profile.

7 . The router bit of claim 1 , wherein each cutting edge of the pair of cutting edges comprises:

a first end;

a second end opposite to the first end; and

a lip extending helically between the first end and the second end defining a cutting direction;

wherein the first end is positioned ahead of the second end relative to the cutting direction.

8 . The router bit of claim 7 , wherein each cutting edge of the pair of cutting edges further comprises:

a first distance measured between the first end of each cutting edge of the pair of cutting edges to the drill axis; and

a second distance measured between the second end of each cutting edge of the pair of cutting edges to the drill axis;

wherein the first distance is greater than the second distance creating a non-linear profile along the lip of each cutting edge of the pair of cutting edges.

9 . The router bit of claim 8 , wherein the lip of each cutting edge of the pair of cutting edges is defined along an axis that is non-parallel to the drill axis.

10 . The router bit of claim 8 , wherein the lip of each cutting edge of the pair of cutting edges is configured to cut a chamfered edge into the work piece.

11 . The router bit of claim 8 , wherein the lip of each cutting edge of the pair of cutting edges is configured to cut at least one curvilinear edge into the work piece.

12 . The router bit of claim 1 , wherein the tip portion comprises:

a first end positioned proximate to the reamer portion;

a second end positioned opposite to the first end at the boring end; and

a pair of substantially vertical cutting edges extending longitudinally from the first end to the second end;

wherein the pair of substantially vertical cutting edges is configured to cut a pair of first substantially vertical walls defining the non-linear profile in the work piece.

13 . The router bit of claim 12 , wherein the tip portion comprises:

a web; and

a pair of substantially horizontal cutting edges extending radially outward from the web to a respective substantially vertical cutting edge of the pair of substantially vertical cutting edges;

wherein the pair of substantially horizontal cutting edges is configured to cut a base wall defining the non-linear profile in the work piece;

wherein the base wall is positioned vertically below the pair of first vertical walls.

14 . The router bit of claim 13 , wherein:

the at least one planar cutting edge is a pair of planar cutting edges extending from the pair of chamfered cutting edges towards the tip portion and configured to cut a pair of second vertical walls defining the non-linear profile; and

the at least one rounded cutting edge is a pair of rounded cutting edges extending from the pair of planar cutting edges to the tip portion and configured to cut a pair of shoulders defining the non-linear profile;

wherein the pair of second vertical walls is defined between the pair of top chamfered walls and the pair of first vertical walls;

wherein the pair of shoulders is defined between the pair of first vertical walls and the pair of second vertical walls.

15 . 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.

16 . The method of claim 15 , wherein the step of cutting the non-linear profile into the work piece further comprises:

cutting the work piece with a lip of each cutting edge of the pair of cutting edges that extends helically between a first end of each cutting edge of the pair of cutting edges the and a second end of each cutting edge of the pair of cutting edges and defines a cutting direction;

wherein the second end is positioned ahead of the first end relative to the cutting direction such that the first end cuts the work piece subsequent to the second end.

17 . The method of claim 15 , wherein the pair of cutting edges and the pair of flutes are oriented in an up-cut configuration.
