## Abstract

A die set for bending work pieces using a power crimping tool, the die set including a first die including a first inside surface and a second inside surface angled a predetermined number of degrees relative to the first surface and a second die including an inside surface corresponding to the first inside surface of the first die and an inside surface corresponding to the second inside surface of the first die.

## Claims

### Claim 1

A die set for changing the shape of a work piece by gripping a first portion of the work piece and bending a second portion of the work piece utilizing a hand held tool, the die set comprising:
a first die including a first planar surface having a first end and a second end relative to a longitudinal axis of the first planar surface and a first bending surface positioned at the first or the second end of the first planar surface, the first bending surface being angled relative to the first planar surface a predetermined number of degrees by an arched rollover surface; and
a second die including a second planar surface having a first end and a second end relative to a longitudinal axis of the second planar surface and a second bending surface positioned at the first or the second end of the second planar surface, the second bending surface being angled relative to the second planar surface and corresponding to the first bending surface of the first die;
wherein the first planar surface of the first die corresponds to the second planar surface of the second die so that the first and second planar surfaces can grip the first portion of the work piece; and
wherein when the first bending surface of the first die and the second bending surface of the second die are moved toward each other the first and second bending surfaces bend the second portion of the work piece to impart an angle onto the work piece.

### Claim 2 (depends on 1)

The die set as recited in claim 1, wherein the predetermined number of degrees is 90 degrees.

### Claim 3 (depends on 2)

The die set as recited in claim 2, wherein the first bending surface of the first die is substantially perpendicular to the first planar surface of the first die, and wherein the second bending surface of the second die is substantially perpendicular to the second planar surface of the second die.

### Claim 4 (depends on 3)

The die set as recited in claim 3, wherein the arched rollover surface of the first bending surface is capable of rounding at least a portion of the second portion of the work piece as the bending surfaces bend the second portion of the work piece.

### Claim 5 (depends on 1)

The die set as recited in claim 1, wherein the predetermined number of degrees is between 0 and 180 degrees.

### Claim 6 (depends on 5)

The die set as recited in claim 5, wherein the predetermined number of degrees is between 0 and 135 degrees.

### Claim 7 (depends on 1)

The die set as recited in claim 1, further comprising slots provided on an outside surface of the first and second dies that can be aligned with tabs provided on the hand held tool on which the die set is to be attached, such that the first and second dies can be slid onto and off of the hand held tool.

### Claim 8 (depends on 7)

The die set as recited in claim 7, wherein at least a portion of the outside surface of the first and second dies are sized and dimensioned to correspond to surfaces on the hand held tool to which the die set is to be attached.

### Claim 9 (depends on 8)

The die set as recited in claim 8, wherein at least portion of the outside surface of the first and second dies are semicircular in cross section.

### Claim 10

A die set for changing the shape of a flat portion of a work piece by gripping a first portion of the work piece and bending a second portion the work piece utilizing a hand-held tool, the die set comprising:
a first die including a first gripping surface having a first end and a second end relative to a longitudinal axis of the first gripping surface and a first bending surface positioned at the first or the second end of the first gripping surface, the first bending surface being angled relative to the first gripping surface a predetermined number of degrees by an arched rollover surface; and
a second die including a second gripping surface having a first end and a second end relative to a longitudinal axis of the second gripping surface and a second bending surface positioned at the first or the second end of the second gripping surface, the second bending surface being angled relative to the second gripping surface and corresponding to the first bending surface;
wherein the first gripping surface corresponds to the second gripping surface so that the gripping surfaces can grip the first portion of the work piece; and
wherein when the first bending surface and the second bending surface are moved toward each other the bending surfaces bend the second portion of the work piece to impart an angle onto the flat portion work piece.

### Claim 11 (depends on 10)

The die set as recited in claim 10, wherein the predetermined number of degrees is between 0 and 180 degrees.

### Claim 12 (depends on 10)

The die set as recited in claim 10, wherein the predetermined number of degrees is 90 degrees.

### Claim 13

A die set for changing the shape of a work piece by gripping a first portion of the work piece and bending a second portion of the work piece using a hand held tool, the die set comprising:
a pair of opposing dies having at least two sets of opposing surfaces, wherein
a first set of opposing surfaces includes:
a first planar surface having a first end and a second end relative to a longitudinal axis of the first planar surface; and
a second planar surface having a first end and a second end relative to a longitudinal axis of the second planar surface; and
a second set of opposing surfaces includes:
a first bending surface positioned at the first or the second end of the first planar surface, the first bending surface being angled relative to the first planar surface a predetermined number of degrees by an arched rollover surface; and
a second bending surface positioned at the first or the second end of the second planar surface, the second bending surface being angled relative to the second planar surface and corresponding to the first bending surface;
wherein the first set of opposing surfaces form a work area that can grip the first portion of the work piece, and the second set of opposing surfaces can bend the second portion of the work piece the predetermined number of degrees.

### Claim 14 (depends on 13)

The die set as recited in claim 13, wherein the predetermined angle is 90 degrees.

### Claim 15 (depends on 14)

The die set as recited in claim 14, wherein the arched rollover surface is capable of rounding a portion of the work piece when the second of the at least two sets of opposing surfaces bend the second portion of the work piece.

### Claim 16 (depends on 13)

The die set as recited in claim 13, wherein the predetermined angle is between 0 and 180 degrees.

### Claim 17 (depends on 16)

The die set as recited in claim 16, wherein the predetermined angle is between 0 and 135 degrees.

### Claim 18 (depends on 13)
