EZARC Countersink Drill Bit Set | 24 Pack | Tapered HSS Nitride Bits | Depth Stop | Screwdriver Bits | Woodworking | Storage Box

Everything You Need for a Professional Wood Finish. In One Box.

Countersinking is one of those jobs where the right bit makes all the difference — a clean pilot hole, a flush screw head, a finish that looks intentional rather than rushed. This 24-piece countersink drill bit set from EZARC gives you everything you need for the entire job in a single, well-organised storage box. Tapered HSS bits with a nitrided surface for 2x longer life, adjustable depth stop collars for consistent depth every time, screwdriver bits, wooden plugs, an Allen key and an extension shaft. Whether you’re building cabinets, fitting furniture or tackling a DIY project, this kit has you covered from pilot hole to finished plug.
