## Abstract

A combination tap and die wrench is provided having a center portion with an aperture extending through the thickness thereof for receiving and retaining tapping apparatus and at least two oppositely extending arm portions extending outwardly from the center portion, each of said arm portions including a plurality of receptacles for receiving and retaining dies. An extension handle is also provided and may be secured to either of the arm portions at their outwardly extending ends. Storage means for tapping apparatus may be provided in the handle.

## Claims

### Claim 1

A combination tap and die stock wrench having a center portion and a pair of oppositely and outwardly extending arm portions from said center portion, said center portion including an aperture extending through the thickness thereof for receiving and positively retaining tapping apparatus and said arm portions each including a plurality of individual die receptacles each adapted to receive and positively retain therein a tapping die, wherein each of said arm portions includes at its outwardly extending end a substantially hollow extension handle for receiving and storing tapping apparatus adapted to be introduced therein through a sealable opening at its outwardly extending end.

### Claim 2 (depends on 1)

The wrench of claim 1 wherein at least three die receptacles are provided on each arm portion.

### Claim 3 (depends on 1)

The wrench of claim 1 wherein said tapping apparatus is positively retained within the aperture of said center portion by means of at least one spring loaded ball plunger.

### Claim 4 (depends on 3)

The wrench of claim 3 wherein each of said dies are positively retained within each die receptacle by means of at least one set screw.

### Claim 5

A combination tap and die stock wrench having a center portion with an aperture extending through the thickness thereof for receiving and positively retaining tapping apparatus and a pair of substantially flat arm portions having opposed surfaces extending oppositely and outwardly from said center portion, each of said arm portions including a plurality of individual die stock receptacles on both opposed surfaces thereof, the receptacles on one surface adapted to receive and retain dies of a pre-determined outside diameter and the receptacles on the opposite surface of said arm portion adapted to receive dies of a different outside diameter; wherein at least one of said arm portions includes an extension handle secured thereto at its outwardly extending end, said handle being substantially hollow for receiving and storing tapping apparatus adapted to be introduced through a sealable opending at its outwardly extending end.
