Tooling Balls and Checking Balls
Available from stock in sizes from 1/8" to 1" in increments of 1/8". ITI Tooling and Checking Balls are made of Type 440C stainless steel hardened to R_c 55-58. Tooling balls are assembled by a proprietary welding technique that retains the high precision and fine finish of the balls.

Ball Plug Gages
Tungsten carbide Ball Plug Gages are quick and easy to use because they can be inserted at any angle. "Go" gages go freely and "no go" gages won't bind. They are particularly effective for giving a feel for bell-mouth, barrel or taper problems. These gages are widely used for spherical seat and bearing race "go" and "no go" gages. They are available in 4,550 sizes from 0.050" in 0.0001" increments. The polished tungsten carbide balls feature class Z tolerance and are mounted on stainless steel shanks.

Gaging Ball and Stem Combinations
ITI supplies answers to special gaging problems with a variety of ball and stem combinations made to precise tolerances. Balls can be any size, and the stem can be any length, diameter and shape. Available in tungsten carbide as well as 440-C stainless steel.
