Incra IRSET12 12-Inch Marking Rule Set
![]() | Average Customer Rating: Recommend Instead of squinting at that blur of lines along the edge of your old steel rule, the Incra 12-Inch Marking Rule Set, lets you mark precisely where you want with zero uncertainty and no eye strain. Incra has re-invented the steel rule by putting micro-fine holes at every scale position (every 1/16-inch and 1/32-inch) to instantly locate a sharp pencil or scribe exactly on target. Using a T-square this guide draws perfectly Product details and pricing info |

- Fantastic Product!
- I would highly recommend this product to anyone looking for accuracy and quality. I was actually surprised at the quality vs. price; and as always Amazon delivered on time without any hassles or delays. Some people claim the Incra precision protractor's are flimsy, but I didn't find this to be true. Make sure you have a 0.5 mm lead pencil though, because anything larger will not fit through the marking slots.

- Good, but too fragile
- These would have been 5-star, but the metal is so thin (almost paper-thin) that it can be bent easily. And if a tool won't hold up, that's two stars to me. If you can treat them very delicately then this is a great product.

- Great Ruler
- This is one of the best ruler sets I have used it is very accurate and easy to use. The design makes them very accurate and easy to use.
One issue I have had is that they are so accurate (to the 1/64) that I have to wear glasses to see which mark I am using. The ruler is well marked and easy to read but it is still to 1/64 of an inch. - 2008-01-18, 0 of 0 people found this review helpful, Rated:
- 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. - 2003-12-14, 8 of 8 people found this review helpful, Rated:
- 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.
