• Industrial‑Grade High Speed Steel for Durability – These countersink drill bits are crafted from premium M2 high‑speed steel with a rotary cutting design for efficient, clean holes. Tough and wear‑resistant, they handle repeated use in hardwoods, softwoods, and non‑ferrous metals.
• Adjustable Depth Stop with Instant Contact Stop – The upgraded aluminum depth limit ring features a built‑in bearing that stops rotating immediately upon contacting the wood surface, preventing over‑drilling. Easily set your desired countersink depth using the hex screw for precise, repeatable results.
• Complete 4‑Piece Set for Multiple Sizes – Includes four tapered pilot bits: 3/16" x 1/2", 11/64" x 1/2", 9/64" x 3/8", and 5/32" x 3/8". Whether you need fine or general countersinking, this set covers a wide range of screw sizes for woodworking, cabinetry, and DIY projects
• Independent Depth Adjustment for Drilling & Countersinking – Both the drilling depth and countersink depth are independently adjustable via the hex screw and depth stop collar. This flexibility allows you to adapt to different material thicknesses and screw lengths for a professional, flush finish.
• Compact Storage Box & Wide Material Compatibility – All components are neatly organized in a lightweight storage box for quick identification and portability. Works perfectly on natural wood, MDF, particleboard, plywood, aluminum, and other decorative materials—ideal for renovation projects and professional workshops.
