Known for their precise, quality clipping and shearing products, Heiniger#s Coarse Blade Set is designed for general purpose clipping for beef and dairy cattle. The coat length after clipping is about 2-4 mm. The bottom blade has 21 teeth while the top blade features 23 teeth. Compatibility is not a problem either. Heiniger blades will also fit Aesculap, Clipmaster, DeLeval and Norton clippers.
