Feature

●【Advantage】 Assist in quick checking of holes, slots and recess up to 6 inch deep. The ends of both contact are head treated steel and precision ground to a radius allowing proper clearance on the smallest hole the gauge will enter.
●【Bore Gauge Material】 The bore gauges are made of carbon steel with chrome plating on the surface. Self centering telescoping gauge has high rigidity, good wear resistance. Telescoping Gage Set has nickel-plated finished and good side arc so that the product has a long service life.
●【Bore Gage Packing】 Total 6Pcs cylinder bore gauges in a ethylene plastic bag, range: 5/16" - 6" (8mm to 150mm), (1 gage: 5/16 - 1/2" range x 4.20" overall; 1 gage: 1/2 - 3/4" range x 4.40" overall; 1 gage: 3/4 - 1-1/4" range x 4.40" overall; 1 gage: 1-1/4 - 2-1/8" range x 5.85" overall; 1 gage: 2-1/8 - 3-1/2" range x 5.85" overall; 1 gage: 3-1/2 - 6" range x 5.85" overall).
●【Scope of Application】 Telescopic spring piston in the hole (or groove), can conduct inner diameter detection, used with micrometer or caliper, with knurled locking device.
●【Unique Design】 The spring tension of bore measuring tool ?gives uniform contact pressure, can detect the inner diameter in a hole (or groove).Spring of telescopic gauge loads with knurled locking knob and knurled holding area.


Description

Features:
Double action handles are rigidly attached to the contact plungers and are automatically self-centering. Assist in quick checking of holes, slots and recess up to 6 inch deep.
