Precision Triga Bore™ 3-Point Gauge Heads for Accurate Measurement - Ideal for Machining, Quality Control & Industrial Applications

Triga-Bore Heads have a large measuring range and are supplied with fixed anvils eliminating operating error. 24 heads cover .236"-7.87" (6-200mm range). Spherical shaped heads are useful in deep bores where holding the bore gage straight in the bore is difficult. The spherical shape allows only a single contact point per anvil on the bore wall.
