THINBIT®, manufactured by Kaiser Tool Company, is pleased to announce the expansion of their GROOVE ‘N TURN® line with ACME THREADING inserts.

ACME THREADING inserts are designed to cut thread sizes 4, 5, 6, 8, 10, 12, 14 and 16 threads per inch. Tools have geometry to cut standard 29° acme thread profiles.  Inserts can be used to cut centralizing or stub profiles by overcutting.  The inserts can be used for internal acme threads on parts with bore diameters of 1.250” and larger.

Available in sub-micron grain carbide grades for ferrous and non-ferrous materials either uncoated or with TiN, TiCN, TiAIN or diamond film coatings.  GROOVE ‘N TURN® ACME THREADING inserts can be used on conventional, Swiss and CNC machines.

Toolholders are available in square shank size 5/16” through 1-1/4” and round shank sizes 1/2” through 1” with straight and 90o presentations.  GROOVE ‘N TURN® ACME THREADING inserts fit existing “L” series THINBIT® toolholders.

THINBIT® offers an extensive selection of 60º thread forms for both internal and external threading.  Custom thread profiles with deliveries from 5 working days are available.

These tools, along with the entire THINBIT® line of cutting tools, will be on display at WESTEC 2015 in Booth Number 2107, or for more information regarding the entire THINBIT® line, please visit our website at
