Features: FAST MEASURING: The Starrett Dial Caliper 120AM-150 provides precise measurements of outside dimensions (OD), inside dimensions (ID), and depth. Use for metal working, woodworking, automotive, and machining applications. | RANGE: This series features a 0 - 150mm range and 0.02mm dial graduation. It has a hardened stainless steel bar, measuring surfaces, rack, gears and depth rod. | FEATURES: This model offers knife-edge contacts for inside and outside measuring, and lock screw for holding sliding jaw in position to ensure a consistent measurement. | EASY OPERATION: It offers one hand use with the thumb-operated, fine adjustment roll, and rack teeth point down to prevent clogging the tool which can lead to measurement errors. | VERSATILE: Used by mechanics and toolmakers everywhere, it offers direct reading, reliability, and accuracy - which makes it one of the handiest measuring tools available.
The Starrett 120AM-150 dial caliper measures 0 to 150 mm with 0.02 mm accuracy. This handy measuring tool allows for reliable and accurate readings with the sharp, black graduations on the No-glare, satin-finished bar, crisp lines on the yellow dial face, and knife edge contacts for inside and outside measurements. One full revolution of the dial is equivalent to 2 mm. The jaw depths on this caliper are approximately 1-1/2” or 38 mm for the outside measuring jaws and 5/8" or 16 mm on the inside measuring jaws. The jaw depths are approximately 1-1/2” or 38 mm for the outside measuring jaws and 5/8" or 16 mm on the inside measuring jaws. The knife-edge contacts can be used to scribe parallel lines on the workpiece. This caliper can be used with one hand through operating the fine adjustment roll with the thumb. The lock screw locks the dial bezel and holds the sliding jaw in position. The depth rod is integrated into the rack of the caliper, unlike many calipers which offer a detachable depth rod, or None at all. The hardened stainless steel components, including the bar, measuring surfaces, rack, gears, and depth rod, offer corrosion resistance, increased accuracy, and long life. Positive split gear anti-backlash control offers increased accuracy over standard gear configurations. Backlash is the amount of clearance between mated gear teeth in the caliper controls, which prevents the gear teeth from jamming. It is undesirable to have much backlash due to the lack of precision offered by the increased amount of play between gears. Certain gear designs can minimize or eliminate backlash; split gear systems actually split the gear into two gears, each half as thick as the original gear. One of these gears is then fixed to the shaft while the other gear is allowed to turn. The free-turning gear is connected to coil springs that rotate it until all the backlash in the control system has been eliminated.
