2nd Update: Jan 30, 2013

So far 2 of the 3 units purchased are working well. I had the 2 checked in my calibration lab and neither tool had a problem. I also recently purchased a 4th to replace the one that failed. I brought the review up to 4 stars because I still think this is a good product. My operators all love this tool and now prefer it over their previous driver. Currently the 3 drivers are only being used by one or two operators so they don't have the same use as the first that failed.

Update: August 27, 2012

Sadly, I had to decrease my rating from 5 stars to 3. It is still a good tool and my operators love it but if they only last 6 months it isn't worth it. I sent the first unit back to my calibration lab for a 6 month overhaul and the results were disappointing. They were not able to get the tool back into calibration. The low end was a little off, around 1 in lb below the setting. The upper limit was worse, around 48 in lbs when set to 40.

I had this particular tool being used 24 hours a day on all my shifts to check for this exact problem. The life span may be a little longer depending on your usage. The highest torque we have is around 36 in lbs.

After 3 months of use with the first article, and my calbration labs approval, I purchased two more that are currently being used in production. They have been in use for 2 months with no problems. Once those have gone through my calibration department for their 6 month overhaul, I will update this review.

(Original Review March 2012)

I purchased this torque driver to test along with others before getting sets for all my operators. So far I have been extremely pleased with the price, performance, and the feedback of my employees.

When considering this tool to purchase - it should be noted that when you are using a tool 24 hours on all shifts (sounds like 24x7) - you also are probably using it more than just once each hour.

Once each hour would result in a 5,000 use cycle occurring every 208 days. However, in a busy industrial environment - using this tool just twice each hour - results in 5000 cycles every 104 days. Essentially - every 90 days. You also have the fact that using any torque wrench in the upper or lower ends - decreases the life of said wrench. All of this information is readily available from CDI. The following are quotes from them as to the care of their tools and torque wrenches in general:

"To determine which torque wrench capacity is best suited for an application, many factors must be considered. However, as a recommendation, use a torque wrench in the middle 50% of the overall capacity of the tool. This will result in longer tool life, ease of use for the operator and increased accuracy from "clicker" type torque wrenches

Torque wrenches should be "exercised" a minimum of three times at 100% of full scale before use

Torque wrenches will last longer if reasonable care is taken. Always unwind handle to the lowest setting after each use. Do not attempt to lubricate the internal torque mechanism. Clean torque wrench by wiping, do not immerse. The wrench should be sent to a qualified calibration lab once every year or every 5000 cycles for re-calibration"

The instructions for this specific micro adjustable torque screwdriver (401sm) - state to have it calibrated and gone through every 5,000 cycles - or one year - whichever comes first. ALL torque wrenches have useful life cycles.

This CDI micro torque screwdriver is a product distributed through (besides Amazon) 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. Amazon 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...
