Mitutoyo – Tooling

Mitutoyo was founded in 1934 by Yehan Numata with one product, the micrometer. Mitutoyo’s philosophy at that time was to make high-quality micrometers, but also to produce them in quantities that made them affordable and available to all of manufacturing. This philosophy was expanded in the next several decades to include a wider product offering focused on mechanical, dimensional gaging products, such as calipers, dial indicators, and other measuring tools.

As electronic technology became more widespread in the 1970s, Mitutoyo applied electronics to its line of dimensional gaging equipment to include electronic, or digital, measuring tools. During this time it also began to offer larger, more complex and more sensitive measuring instruments, including optical comparators, form measuring equipment, and coordinate measuring machines (CMMs). As statistical process control (SPC) was introduced, Mitutoyo led the world in the development of output gages, interfaces, data collectors and analysis software to take advantage of this new metrological science.

When the computer made its way into the field of metrology, Mitutoyo again shifted its focus to include this technology into its product offering and push measuring accuracies into the sub-micrometre range. Today, Mitutoyo presents its 6,000+ products as integrated, computer-based metrology systems, where they can be interconnected to form closed-loop-measuring networks.

Mitutoyo America Corporation was formed in 1963 and is headquartered in Aurora, Illinois (just outside of Chicago). Mitutoyo America offers the full product line of precision measuring tools, instruments and equipment with a distribution network, training and education classes, software development, and service support to provide a comprehensive metrology organization.

Dr. Yehan Numata is also the founder of Bukkyo Dendo Kyokai (BDK), the Society for the Promotion of Buddhism, which sponsors the Buddhist Canon Translation Project.

Indi-Square Company

The INDI-SQUARE COMPANY has been manufacturing precision squareness measuring instruments at our manufacturing location in Rochester, New York since 1960. INDI-SQUARE instruments are used by manufacturers and machine tool builders industry wide in inspection departments and tool rooms. Because they are portable, they are easily used on the shop floor for checking in process work at production setups or on large parts themselves. The INDI-SQUARES provide precision squareness and vertical straightness measuring with the exclusive proven anti-friction lifetime sliding mechanism.
(Model 8) and (Model 18) Indi-Squares are simple to use, allowing the user to rapidly check the squareness and straightness of surfaces to .00005 over 9″ of travel and .0001 over 18″ of travel.
INDI-SQUARE measuring instruments are durable. No lubrication or special maintenance is required. They are warrantied for a one year period. If damaged or broken, they may be repaired at the factory and returned with a new “Certificate of Repair and Calibration” and a new full one year warranty.

S-T Industries

The S-T Industries Story

For more than 60 years, SCHERR-TUMICO measuring products have been produced in Southwestern Minnesota. The tubular frame micrometer was introduced in the early 1940’s, the Model 1500 vertical beam optical comparator in the 1950’s and the Model 2500 30″ optical comparator in the 1960’s. Since 1983, S-T Industries, Inc. has expanded the product lines to include a full range of precision hand measuring tools, optical comparators and video inspection systems.


Every SCHERR-TUMICO optical comparator and video inspection system receives a thorough inspection and certification before it leaves our factory. This assures you there will be no surprises at your facility. These products are not mass produced on an assembly line, but hand crafted and tested through each step of the process to guarantee that you will receive a reliable and proven instrument.


SCHERR-TUMICO optical comparators and video inspection systems are designed to give you the best value for your investment. We have a unit for any job or budget. Whether you need a small, economical machine or a large, CNC measuring system, you’ll find we have a product to fit your needs. We also build special systems and tools for unique applications.

Parallel within 0.0001″, square within 5 seconds, 0.00005″ per foot surface accuracy…published manufacturing data like this tells the quality story of Taft-Peirce Production and Inspection Equipment. Add to announced manufacturing tolerances the key elements of job-tested design and controlled manufacturing processes, and you have the basic success story of a product line that has proved itself in use for over 100 years.

Specifications You Can Trust.

There is no secret about the accuracy of this internationally accepted line of tools. Taft-Peirce’s policy has always been to list key tolerances in print. Look for the actual figures as you read through this catalog – you can buy tools with confidence when you know their quality and the reputation of the manufacturer who stands behind them.

Design Notes, Yesterday and Today.

The first tools in this specialized line of set-up, production and inspection equipment were developed from models originated and proved under actual manufacturing conditions in the world-famous Taft-Peirce Contract Service Division. Through the years, this series of tools has been tested, refined and expanded, until its breadth and total reliability have earned a reputation unmatched in the field of precision manufacture. Today a full-time research and development group is continually searching for new ideas and recommending changes wherever the performance of existing tools can be improved.

Manufacturing Controls.

Taft-Peirce, a Company known for its precision products, employs a policy of strict quality control. Metallurgical analysis specifies and controls the uniformity of raw material; inspection stations control dimensional relationships of work in process; and final inspection is conducted in up-to-date gaging laboratories equipped with every type of modern measuring instrument.

Taft-Peirce Production and Inspection Tools are available through representatives in your area — ask them, or contact the plant directly, for additional data on standard equipment, or special designs, sizes and materials needed to meet unusual requirements. For the set-up, production, and inspection equipment that shop men know and trust, make sure you TAKE IT TO TAFT-PEIRCE.
