✔️ VERSATILE COUNTERSINK & PLUG CUTTER SET – This professional set includes two adjustable countersink and counterbore cutters in #8 (11/64″) and #12 (7/32″) with HSS M2 tapered drill bits (designed for 3/8″ and 1/2″ screw heads), plus two wood plug/dowel cutters in 3/8″ and 1/2″ diameter. Perfect for creating flush, professional finishes in woodworking projects.

✔️ PRECISION CUTTING & SEAMLESS FINISHES – The adjustable countersink and counterbore cutters allow you to drill clean, precise holes, while the wood plug cutters create perfectly sized plugs or dowels to conceal screw holes seamlessly.

✔️ DURABLE, HIGH-QUALITY MATERIALS – The HSS M2 (6542 grade) drill bits provide exceptional sharpness and longevity, while the Carbon Steel #45 plug and countersink cutters are Black Oxide coated for corrosion resistance, ensuring long-lasting performance.

✔️ PROFESSIONAL-GRADE WOODWORKING TOOLS – Ideal for cabinet makers, furniture builders, DIYers, and professional woodworkers, this set delivers accurate, clean drilling and seamless plug fitting for hardwood, softwood, MDF, and plywood.
