The Andis 66240 replacement blade set restores the cutting assembly on compatible US-1 and LCL clippers. It includes both the blade and cutter, giving users a matched replacement set when the existing cutting components need to be changed. This is an adjustable blade system with a size range from 000 to 1.

According to the manufacturer package, that range leaves approximately 0.5 to 2.4 mm of hair, also shown as 1/50 to 3/32 inch. The ability to vary the setting supports short cutting and blending work with the same blade set. Carbon-steel construction is intended to provide a durable cutting edge for regular use.

Check the model designation on the clipper before selecting this part: the official fit list names US-1 and LCL. Use the clipper's blade replacement instructions when fitting the set. After installation, remove trapped hair, clean the blades as directed and oil between cuts to maintain their working surfaces. Andis lists a 10-day warranty period for item 66240.
