Professional Precision Tool Set!
Telescoping gages are used for determining the true size of holes, slots, and recesses up to 6" (150 mm). The ends of both contacts are hardened and ground to a radius to allow proper clearance on the smallest hole the gage will enter. The final hole size is obtained by measuring over the gage contacts with a micrometer or calipers.
Features:
- Easy to adjust
- Spherical measuring faces hardened
- Satin chrome finish
- Range: 5/16" - 6" (8mm - 150mm)
