{Easy Access To The Smallest Hole}: The ends both of telescopic cylinder bore gauge contact are head treated stainless steel and precision ground to a radius to allow clearance of telescopic bore gauge on the smallest hole gage will enter
{Double action rigid handle}: This telescopic bore gauge can quick check holes, slots and recess up to 6" deep
{Smooth surface}: Telescoping gage set has nickel-plated finished and good side arc so that the product has a long service life
{Constant Spring Tension}: The spring tension of telescopic bore gauge set gives uniform contact pressure, can detect the inner diameter in a hole (or groove)
{Unique Design}: Spring of telescopic gauge loads with knurled locking knob and knurled holding area.Used for measuring holes, slots, grooves, and recesses in woodworking, metalworking, machining,and pattern-making applications
