Product Description

Each set includes the Precision Marking Rule, Precision T-Rule, and Precision Bend Rule, along with a fine (0.5mm) marking pencil. Micro-fine guide holes and slots at every 1/16", 1/32" and 1/64" scale position instantly locate your sharp pencil or scribe at the exact measurement with zero uncertainty and no eye strain! Our Professional T-Rules even offer marking holes every 1/100". This is unmatched in the industry. Incra Marking Rules have the most precise marking system available. Each .5mm hole or slot lets your Incra .5mm pencil mark the work perfectly without worry of parallax or angle slip. One excellent use of the Incra T-Rule is shown here. With the pencil in a marking hole, slide along any edge to draw perfectly placed horizontal lines. And of course, the old issue of bending a mark accurately from one side to the other is now a piece of cake with the Incra Bend Rule.

Fabulous-easy and accurate!
I could not be more pleased with these rules. They have a series of very small holes aligned with the usual ruler measure marks. You mark your measurements by using a mechanical pencil (or other thin writing tool) and putting the point into the appropriate hole. Your mark is a neat pinpoint lined up eactly with the ruler mark. The increments of measure are very small, so I have not yet had a situation where I couldn't measure what I needed. The marks are easy to read. The rules work well for drafting or for marking materials. One note: They are made of very thin metal (or composite?), and so are not rigid. I actually like this, but if you prefer a rule with some heft, you might not like this.

I'm hooked on Incra "Mania"
I first bought the Incra TSIII-32 table saw fence. I became indoctrinated into the Incra system. One that creates unbelievably accurate results with the least amount of effort. When I tell others that my fence-table saw is adjusted so that I can cut any size board, take out a dial caliper and it is accurate to .002", then get mad at me and tell me I'm either wrong or not telling them the truth, but it is true.
I then bought the 6" rule, and it is so accurate, I measure all of my other measuring devices by it. I wound up throwing out my far less than accurate tape measures and rules. Oh a lot of them are accurate through out the rule, but the beginning reference could be off somewhat. What else matters? Some people are not into getting totally accurate measurements. My philosophy is to strive for perfection, and settle for excellence. So onto the rule.
Since it has these tiny holes that you place the tip of a mechanical pencil into, then slide the rule along your workpiece. Thereby insuring a perfect line, exactly the distance from the edge. No holding the pencil along a rule, and sliding it along, making a varied line. If you use these rules, and gently begin your cut a hair over the line, you can tweak the workpiece up to the edge of your blade at exactly the mark line.
I use the 6" so much, that I decided to get the 12" complete set, which includes the edge-corner rule etc. I know that when I need to mark a workpiece greater than 6", I am going to be cursing myself for needing to use a ruler and a try to make the mark at the right spot method.
The thing about the Incramental system, in all of the their equipment, is that it takes less time to make a perfect cut. Some people feel that this kind of accuracy is not essential, but once you get into perfect fitting cuts, your quickly spoiled. Incra is unique. Check out all of their items. This rule set is a nice addition to your arsenal. Highly recommended.

Best on the market.
I calibrate measurement tools for a living and it's not very often I'm impressed by tools in this price range. I also almost never give anything 5 stars. These are the exception.

No measuring device is "exact" but, after calibration, I found these to be as accurate as rulers costing 5 times as much. Also, the aluminum bar is amazingly repeatable. I found that removing and replacing the bar caused no degredation in accuracy. So don't be affraid to adjust the bar to suit your application. As long as the ruler is seated against the stop it will have a remarkable accuracy.

The price is the final star in this package. I would expect to pay twice this price to get even one ruler this accurate and useful. But here they give you three. You can't go wrong with these.
