The Jonard AHC-10 adjustable hole cutter earns its living cutting clean, dust-controlled circles for speakers, recessed lights, and access holes — and like any cutter, its blades are consumables.
The AHC-10RB is the genuine replacement set: two left-cutting blades and two right-cutting blades (two complete blade sets) that restore factory-sharp performance in a few minutes.

Fresh blades matter more on an adjustable circle cutter than almost any other tool.
Dull edges tear drywall paper instead of scoring it, wander on plywood, and chip acrylic — turning what should be a clean trim-ring-ready hole into patch work. These ultra-sharp OEM blades cut cleanly through plywood, sheetrock, plasterboard, and acrylic sheet up to 1-1/16" (2.7 cm) thick, the full working range of the AHC-10.

At a fraction of the tool's price, a spare set in the case means a mid-job blade change instead of a mid-job hardware run.
If the AHC-10 is on your truck, these should be too.
