Self-Locking Tap Extension: 1-1/4" NPT, 12" Length

Unique self-locking feature offers the smallest OD of any Tap Extension in the industry and the ideal solution for close quarter & long tapping problems.  No set screws or collets required!

Each extension is designed for a specific tap size.  The tap shank and tap square dimensions conform to the size standards of leading tap manufacturers.  Because the Tap Extension has no set screws or collars which extend shaft diameter, it offers unique capabilities in allowing the user to tap close to the edge or shoulder of the workpiece.

How does it work?


The secret to the Tap Extensions unique self-locking design is a precision machined EDM cavity that receives the end of a standard tap.  The bottom part of the cavity (A) is a tapered square with a wall angle of less than one degree, which receives the square section of the tap and grips it so securely that a thin drift is needed to separate the tap and extension.  The cylindrical part of the tap shank fits tightly into a similar cavity in the extension (B), providing resistance to bending.
