Self-Locking Tap Extensions - For use with Inch, Metric & NPT Taps
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
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?
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.
