Starrett Dial 3202-12 Caliper Measuring Tool
The Starrett 3202 Series Dial Calipers provide quick, accurate measurements of outside dimensions, inside dimensions, and depth. The dial caliper is the most versatile precision hand tool on the market and has been the first choice of metal working professionals for decades. This series features 0-12" range and .001" graduations, in Fitted Case.
Product description
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 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 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. The rack teeth point down to keep foreign matter from clogging the gear operations. This prevents measurement errors where metal chips could interfere with proper caliper operation.
Calipers measure the distance between two opposing sides of an object. They make inside, outside, depth, or step measurements, according to their type. Calipers are commonly used in architecture, metalworking, mechanical engineering, machining, manufacturing, carpentry, and medicine. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. More complex calipers use two sets of jaws instead of legs and have up to two graduated scales. Vernier, dial, and digital calipers give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw, and another jaw with a movable pointer that slides along the scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The dial caliper is used also for measuring size differential between two objects. The digital caliper takes the same sort of differential measurements as the dial caliper by zeroing the display at any point along the slide, with an LCD (replacing the dial) that displays a single, easily read value in both English and metric units. Some digital calipers can hold data readings between measurements and send them to data collection devices.
The L. S. Starrett Company was founded in 1880, originally manufacturing bench vises, squares, and other tools. They acquired other companies throughout the years, expanding their services into making precision measurement instruments and tools, such as calipers, micrometers, saw blades, and gauges. Starrett is headquartered in Athol, Massachusetts and has manufacturing facilities in Brazil, the United Kingdom, China, and other locations.

Question: | what kind of battery torch flashlight |
Answer: | I just put this scope on my AR yesterday and went and sighted it in this morning! Was real easy to sight in, the magnification was at 12 was pretty awesome and clear! I spotted for my buddy sighting in his scope at 100 yards and had no problem seeing where his bullets were hitting! I ran about 100 rounds through and it stayed dialed in after I set it! The only negative I have to say about it is it seems like I have to be closer to the eye piece than I am use to... about 3-4 inches away. For the price I am happy with it! Plus the green laser and red dot optics work great and it come with the mounting hardware and batteries! |

Starrett 120AM-150 Dial Caliper, Stainless Steel, Yellow Face, 0-150mm Range, +/-0.03mm Accuracy, 0.02mm Resolution
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.
Product description
The Starrett 1202F-6 dial caliper measures 0 to 6 inches with 0.01” and 1/64” accuracy. This handy measuring tool allows for reliable and accurate depth, inside, and outside readings with the sharp, black graduations on the no-glare, satin-finished bar, crisp lines on the dial face, and knife edge contacts on the jaws. The dial’s inner, decimal scale is white, while the outer, fractional scale is yellow.
One full revolution of the dial is equivalent to 0.100”. 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.

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. Double pinion anti-backlash systems have two round gears (also called pinions) in contact with the rack gear that extends down the length of the caliper itself. The two pinions have a lower chance of disengaging with the rack gear than a single gear, thereby keeping the caliper more accurate than a single gear anti-backlash system. The rack teeth point down to keep foreign matter from clogging the gear operations. This prevents measurement errors where metal chips could interfere with proper caliper operation.

Question: | Is this starrett product made in America or China |
Answer: | It is made in China, but it is well made. |
Question: | Does this item include any sort of case with it, or would I need to purchase one |
Answer: | Thank you for bringing this to our attention. The 1202F-6 comes with a plastic case. We will change description and add a case photo. |
Question: | This looks identical to the cheap fractional dial calipers (oshlun). same cheap mechanism vs mitutoyo. Anything outstanding to justfiy price |
Answer: | I also have a couple of cheap Chinese-made dial calipers. This Starrett caliper, though also made in China, is far superior. While the design is the same, the "fit and finish" and durability are quite good for this price point. It is more than adequate for woodworking. The scale is 1/64, but it is easy to estimate down to 1/128--although that is beyond what's needed in most woodworking situations, except for the most precise joint making. I see this tool as a good compromise between the truly cheap stuff and the best (and most expensive) machinist's calipers. |

The Starrett 120B-12 dial caliper measures 0 to 12 inches with 0.001” accuracy, and 3-inch nib jaws for heavy-duty use or accessing more measuring area than conventional calipers. The jaws measure from zero for outside measurements and from 0.300” for inside measurements. This handy measuring tool help ensure reliable and accurate readings with the sharp, black graduations on the no-glare, satin-finished bar, crisp lines on the white dial face, and knife edge contacts for outside measurements.
