This instrument is widely used to evaluate the adhesion of various coatings. A precision-machined wheel with 6 or 11 cutting blades, available with different blade spacings, is mounted in a handle. The test is performed by making two sets of parallel cuts at right angles to each other. The resulting lattice pattern is then either brushed or cleaned using adhesive tape
Depending on the coating thickness and the blade spacing, the results can be classified against a standard scale. The instrument features a long-life cutting tool with six cutting edges and a comfortable wooden handle. When used on a multi-coat system, it can also assess the resistance of individual coating layers to separation from one another
The Cross Hatch Cutters conform to the requirements of ISO 2409, ISO 16276-2, ASTM D3359, ASTM D3302 and BS 3900 E6

Technical Specification
Eight cutting edges: When an edge becomes dull, loosen the nut and the top thrust screw, then rotate the cutter to select a fresh cutting edge
Blade spacing: 1 mm
Number of teeth: 11
Number of squares in the grid: 100
Note: The number of squares depends on the number of cutting teeth: 6 teeth produce 25 squares, while 11 teeth produce 100 squares
