## Description

CDI Torque Micro-Adjustable Torque Screwdrivers offer versatility for applications that require more than one torque value. These torque screwdrivers are particularly suited for the electronics industry and for instrument assembly work. A simple, cam-over design prevents over-tightening and possible damage to components. Torque settings are easily and accurately changed with a unique adjusting knob and easy-to-read window scale. Adjusting the screwdriver is simple. Just pull out the adjusting knob to unlock, turn to the desired setting, then push the knob in until it clicks! Positive locking knob makes accidental setting changes impossible. Automatic lock in counterclockwise direction makes fastener removal a snap. CDI was founded in 1968 and over the years has developed into a world class torque products manufacturing company. The company earned its ISO 9001 International Quality System Certification in 1998, demonstrating a commitment to provide our customers with the highest quality torque measurement and torque limiting devices in the world. CDI has long been a major innovator and leader in electronic torque measurement and torque calibration equipment.

Review: This CDI micro torque screwdriver is a product distributed through (besides desertcart) Snap-On. This is one of those tools that I don't use that often, but when its needed it is Really needed. Before I bought this item a little over a year ago I did quite a bit of on-line research and discovered that this CDI tool was literally the "only game in town" in terms of accuracy and reliability. The only other contender that even came close (but not very close) was a torque screwdriver sold by Brownells. Since I do not have a calibration lab I went by the accounts of multiple on line sources, and would suggest that you might do the same...things might have changed in the past year. desertcart had the best IN STOCK price I was able to find a year ago. I do my own gunsmithing and use this tool whenever a precise amount of torque is required per a manufacturers specifications. The torque settings are easy to see and adjust within one inch pound increments. The tool accepts regular screwdriver type bits, and therefore will accept just about anything used to tighten small machine parts. So whether you are tightening a screw or a nut (or something in between), and you have the bit to fit your application, this will do the job for you. The build quality on the tool is excellent. It has the heft of a solid little machine and the handle affords a positive grip that lets you apply the downward pressure necessary to keep your bit solidly on the screw and thus avoid any slippage that could mar your workpiece. As far as I can tell (without a calibration lab) this tool gives the proper, repeatable result. I have not stripped a screw or experienced a malfunction of any sort connected with the use of this item. I am very picky when it comes to tools and machines...I earned a living most of my life as a clockmaker specializing in the restoration of antique clocks. These days it is difficult/impossible to acquire high quality tools at a reasonable price. This CDI torque screwdriver is a rare exception in a world of shoddy tools that simply don't measure up to any standard of quality. I believe the reviewer that downgraded this $100+ tool should look toward the Much More Costly torque devices that are intended for 24/7 usage. Under "normal" use I would expect this tool to last the craftsman a lifetime. Kudos to desertcart for making this reliable, high quality tool available to the workman at a good price.
Review: Excellent quality torque wrench for spaces too tight for a ratchet style torque wrench.
