Combination square sets are one of the handiest measuring tools as the basic two-piece square set (ruler and try square head) can be used as a small spirit level, plumb level, internal and external try and mitre square, simple marking gauge and height gauge.
The square head has a miniature scratch awl located in the base to mark work pieces with a face that can be used on 90 degree and 45 degree angles. The protractor head can move in a 180-degree range and also has a bright bubble level to check horizontal levels, while the centre marker head is handy for locating the centres of round work pieces.
The iGaging set is machinist-shop quality to the US standard with accuracy over the blade of +/- 0.1 degree. All heads are heavy stabilized cast-iron and machined to standard. We doubt you will find another set with this kind of quality at this price. The 2.18mm satin ground blades are graduated in imperial on both sides. Both sets come with sturdy storage cases and will get a lot of use in your workshop.
