Abstract
A T-slot router bit for simultaneously cutting a T-slot groove into a work piece and withdrawing pieces of cut work piece from the T-slot groove in a single pass. The T-slot router bit includes a shank end, a boring end opposite to the shank end, a shank that extends from the shank end and is adapted to engage with a chuck of a router, a body that extends from the shank to the boring end and defines a T-shaped configuration, a pair of helical flutes of the body that extends between the shank and the boring end, and a pair of cutting edges that extends between the shank and the boring end.
Claims18
A T-slot router bit, comprising:
- a shank end;
- a boring end opposite to the shank end;
- a shank extending from the shank end and adapted to engage with a chuck of a router;
- and
- a body extending from the shank to the boring end and defining a T-shaped configuration, 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 a T-slot groove;
- 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 T-slot groove;
- and
- the tip portion extending from the reamer portion to the boring end and configured to cut a second portion of the T-slot groove vertically below the first portion of the of the T-slot groove;
- a pair of helical flutes of the body extending between the shank and the boring end;
- and
- a pair of cutting edges extending between the shank and the boring end;
- wherein the body is configured to simultaneously cut a T-slot groove into a work piece and withdraw pieces of cut work piece from the T-slot groove in a single pass.
A method of cutting a T-slot groove into a work piece in a single pass, comprising steps of:
- engaging a shank of a T-slot router bit with a router;
- introducing the T-slot router bit and the router to the work piece;
- aligning a body of the T-slot router bit with a side wall of the work piece, wherein the body defines a T-shape configuration;
- cutting a pair of top walls of the T-slot groove, via at least one chamfered cutting edge of a reamer portion of the body, in the single pass;
- cutting a pair of first vertical walls of the T-slot groove, 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 T-slot groove, 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;
- wherein the pair of top walls is chamfered relative to a top surface of the work piece.
