NT60 Hooking cutter P/N 7406 This is the "Quick Release Chuck" that holds the cutter/blade/bit: 7403 or 7403H. During use, it gets very hot due to friction passed through the bit from the ground.
The DW45 and the Husqvarna® CL400 uses a different Hooking Cutter that requires a hex wrench for changing the bit. Send an email to order 7710.
***Very Important*** Remove the cutter/blade/bit, clean and grease the bit and receptacle in the 7406 with WD-40 or an equivalent anti-seize lubricant after each use. Without cleaning/greasing after each use, the bit will seize and cannot be removed from 7406.
Buy an extra one to keep it on hand because eventually 7406 does wear out!
